Frequently Asked Questions

Below you find our collection of frequently asked questions.
If you still are unclear about certain issues related to your tour or our services, we recommend to you to browse through the list and see if you find some answers to your questions here.

Diving Silfra

Can I bring my Go Pro or my waterproof camera on tour?
You are free to take your own photos or video on tour with us, with a go pro or any other camera in an underwater houseing. However we kindly require that your equipment is attached to your body in one way or another, for example with a wrist band. Many of our customers have taken their go pro’s snorkeling and diving without problems related to the cold water, but if your photography equipment comes with instructions of how deep and/or cold you are allowed to take it underwater, we strongly encourage you to follow them thoroughly. We do not take any responsibilty of lost or damaged photography gear that may happen on tour with us.
What if I only want to do a single dive? Does it cost the same as a double dive tour?
Unlike many other dive centers around the world that charge tour prices per tank, our tour price is calculated per tour due to the Icelandic weather conditions. Our tour always includes one dive, but we try our best to do a second dive when conditions allow it. For that reason, there is no price difference if you wish to only do a single dive when there is a possibility of a second one.
When is the best time to go?
Each season has its own pros and cons. Spring and fall are best for those who like to stay out of the crowds. While we dive in small groups, some of the on-land sites we visit are popular among your run of the mill tourist and, frankly, can get a little crowded, although we do know of quite a few out of the way gems. Late spring you´ll see the vegetation come alive and the birds and the bees buzzing by with excitement. The autumn colours of the turning leaves (yes, we have leaves!) are definitely something to behold and the weather is often calm and the air crisp. Summer is the busiest season, and for a good reason. It´s the warmest and most lush time of the year with nature in full bloom.

From a diving stand point, it makes little difference which of the three seasons you visit as the dive sites, visibility and marine life are pretty constant through out, varying more from day to day, than from season to season. The ocean temperatures are warmest, however, in summer and fall – about 8-12°C.
What is the best time of year to dive Silfra?
There is no best or worst time to dive Silfra. Every season and every weather has its advantages. A calm and overcast winter day will be amazing with beautiful reflections in Silfra´s water surface. A windy summer day with waves will cast sun ripples onto the Silfra bottom... a sight you will never forget. Generally in the summer there are more snorkelers & divers at Silfra, so the winters are calmer.
What size / type of SCUBA tanks do you use?
We use steel tanks due to better buoyancy properties. We use both 12 liter and 15 liter bottles. We can also offer both single and double valves. Please let us know in advance which tank configuration you require for the equipment you bring, so we can have it ready for you.
What type of valve/fittings do you have on your SCUBA tanks?
All our tanks have DIN fittings. If you bring a regulator with a Yoke fitting, also known as INT, we can bring an adapter to screw into our DIN valve. Please let us know in advance.
Do you see any life in Silfra?
No, not really. Silfra is a scenic dive and even though there are plenty of fish in Thingvellir lake, we hardly see them in the Silfra fissure itself.
Are the dry suits very tight / uncomfortable?
We use top quality equipment for our Snorkeling and Scuba Diving tours. The dry suits only do a certain amount of dives / time before they get sold and replaced by new ones. This ensures that our guests will always dive/snorkel in top notch dry suits frequently tested, serviced or replaced. However, it is of high importance to provide us with your correct size (height and weight), so we can make sure to bring the best fit for you. If we receive an incorrect size, the guest will receive and incorrect dry suit fit. We assure you that your size information as well as all other personal information stays confidential with us. We also want to point out that if you are sensitive to having something tight around your neck and/or wrists you might feel uncomfortable in a dry suit. It goes with the territory to have a well sealing neoprene neck seal and rubber wrist seals in order to stay dry.
How far do I have to walk with the dive gear?
It lies in the nature of the geography of Silfra that we have our entry point at a different location than the exit point. It is somewhat a drift dive. From the exit point at the edge of the Silfra Lagoon we need to walk back to the car park. The distamce is approx. 250m and the walk can get quite exhausting with full dive gear. If it gets to heavy for you, please ask your guide to help you or just leave some of your gear behind. We will pick it up for you a bit later.
Can I bring my own dive equipment?
Yes, you are welcome to bring your own equipment and will receive a ISK 5.000,- discount of the day tour price when bringing the full set of dive gear excluding tanks & weights. Please make sure that your equipment is serviced and rated for cold water diving. If your equipment fails you compromise your safety and miss the dive.
What dive/snorkel equipment do you use?
Please read details about our dive equipment on our equipment website.
Is it cheaper if I do only one dive?
If a diver decides to do only one dive, no refund is granted unless it is due to a fault of DIVE.IS, e.g. equipment failure.
Do you guarantee 2 dives on the Silfra Day Tour?
We always try to do 2 dives. If the air temperature drops below 0°Celsius / 32°Fahrenheit, we do only one dive due to safety reasons (the equipment will freeze after the first dive). This happens usually in the winter season only.
Do you rent out UW cameras or do you take photos on the Silfra tours?
Our dive & snorkel guides usually carry an underwater camera on the dives and when snorkeling in Silfra. These photos are available for purchase for the price of ISK 2.990,-. The photos will be uploaded as high resolution images on dropbox. Please note that we can not guarantee that photos are taken on every single tour. The reasons are mainly due to safety. Our dive guides often leave the camera behind on the first dive to have the hands free to help the divers. The same can happen on snorkelling tours if the guides evaluates that members in the group need help in the water.
How deep are the Silfra dives?
The maximum allowed depth in Silfra is 18 meters / 60 feet. Depending on the qualifications and experience of the divers, the dive might be shallower for safety and convenience.
How long are the Silfra dives?
Each of the Silfra dives is usually between 30 and 40 minutes long.
Will I get wet when diving or snorkelling?
When diving or snorkelling in a dry suit, you will generally keep dry and warm. We use BARE dry suits and undergarments of the highest quality and have over 50 of them in all standard and non-standard sizes. Our rental dry suits do only a certain amount of dives before they are sold and replaced with new suits. They are inspected after every tour to assure a minimum of possible failure. However, dry suits are often custom-made to fit each and every individual. This is especially the case with regard to the wrist and neck seals sizes. Even though we do our very best to prevent it, in rare occasions it does happen that someone gets wet.
Will I get very cold on this dive?
Our dry suits and thermal undergarments are of highest quality and will keep you warm and comfortable even though the water is just above freezing. Still, we recommend you bring thin long underwear for additional comfort and hygiene. However, it is usually in the winter time that guests who are not well enough dressed for the weather get cold before dressing into our equipment. Hands can sometimes get a bit cold in the end of the dive. Even though we use the best and thickest dive gloves: 7 mm neoprene three finger mittens. It depends on the person and most people don‘t get cold hands at all, but some do. The cup of hot chocolate after the dive will help to warm them up again.
How cold is the water in Silfra?
The water temperature is 2-4°Celsius all year around. This converts to 35-39°Fahrenheit.
How far is it to Silfra from Reykjavik?
It is about 60 km from Reykjavik to Silfra and it takes a little less than one hour to drive the distance by car. If you choose to drive yourself and don‘t know the way, please plan in a buffer so the group doesn't have to wait for you. You can find a map with directions on our Contact page.
Is food included on this tour?
We offer light snacks such as cookies and hot chocolate to warm up after getting out of the water, but this tour does not otherwise include food. However, we do stop at a service station in Reykjavík where you are able to purchase something more substantial.
I use glasses, is that a problem?
You can not wear glasses underneath the dive mask! If you have bad eyesight  you either need to bring your own prescription dive mask or lens inserts with your own matching dive mask. There are opticians in Reykjavik that you would be able to purchase contact lenses with. However, that needs to be at least a day in forehand.
Can I take the PADI dry suit course on this tour?
Yes you can and we strongly recommend it. Please read all about the PADI Dry Suit Diver Specialty Course.
I need to be dry suit experienced / certified in order to participate in this tour?
If you are not experienced in dry suit diving we recommend that you take our PADI Dry Suit Specialty Course. This course provides you with very useful knowledge and training. The course is conducted separately from the Silfra Diving Tour, but you will do at least one of your certifying dives in Silfra. You will enjoy this dive much more and will be able to appreciate Silfra without struggeling with your buoyancy as much. Further you will get the PADI Dry Suit Diver certification, which is a prerequisite for many other cold water dives around the world. However, if you want to just dive Silfra and don‘t do the dry suit course, you can. Please prepare yourself theoretically by studying the www.drysuitdiving.org  website and mentally by knowing you are up for a challenge.
I forgot my certification card. Is there any way to look my certification up online?
If you are PADI or SSI certified we can look you up online. We need you full name (incl. middle name) and your birth date before the tour starts. When you meet our guides you will need to present an ID. If you are certified with any other organization, we are unfortunately unable to look you up. In this case you will not be able to participate.
What type of certification do I need in order to participate in this tour?
You need to be a PADI Open Water Diver or above or proof equivalent certification from another organization. The PADI Open Water Diver certification means that you can dive down to 18 meters without the direct supervision of an instructor, and if you are certified through a different diving organization, your certification must meet that criteria as well.
Do you pick me up at my hotel or do I need to come to a pick up point?
Yes, we will pick you up at your hotel in central/downtown Reykjavik.  Transportation is included in the price of the Diving Silfra Day Tour, but for snorkelers the transportation service costs an additional 5.000 ISK.  If you stay outside Reykjavik, you need to arrange your own transport into Reykjavik, preferably the BSI bus station, where we can fetch you. You can also meet us in the National Park Thingvellir if you have your own transport.
My friend wants to snorkel, can we do the tour together?
Yes, but if you need transportation from Reykjavík we unfortunately cannot guarantee that we will be able to pick up snorkelers in the same van as the divers.  The only way to guarantee that you will travel together to Silfra is if you drive yourselves.  Once at the site, divers and snorkelers are split into separate groups with different guides, but it is a small area and you will surely see each other.  Please note that national park regulations do not allow divers and snorkelers to be in the same spot in the water at the same time.

What is the weather in Iceland like?
During our summer months (June, July & August) it's sunny and warm(-ish) about a third of the time, overcast and wet about a third of the time, and somewhere in between about third of the time. The Icelandic weather famously changes at the drop of a wooly hat, so hope for the best and prepare for the worst – that means bringing your sun screen and shorts as well as your all-weather gear. Even in the middle of summer the temperatures can get low (to below 10°C at night) so a good fleece – or better yet, Icelandic wool – will be essential, along with a hat and maybe some gloves. It's called Ice-land! …the clue is in the name;-). Also, while we tend not to get heavy, sustained rain, our summers can see their fair amount of precipitation, keeping the island green and lush.
Do you see any life in Silfra?
No, not really. Silfra is a scenic dive and even though there are plenty of fish in Thingvellir lake, we hardly see them in the Silfra fissure itself.

Multiple Day Tours

What clothes/equipment do we need to bring on your Multi-Day Dive Tours?
In terms of personal gear, all your regular travel kit, plus some warm, wind and water proof clothing. Even in the middle of summer the temperatures can get low (to below 10°C at night) so a good fleece – or better yet, Icelandic wool – will be essential, along with a hat and maybe some gloves. It´s called Ice-land! …the clue is in the name ;-). Also, while we tend not to get heavy, sustained rain, our summers can see their fair amount of precipitation, keeping the island green and lush. Therefore you´ll need some form of rain protection to keep you dry between dives and on our sightseeing stops.

In terms of dive gear, most of our multi-day dive tour participants bring their own full sets of dive equipment. However, we do have a full range of top of the line dive equipment for hire at reasonable rates. Contact us for a price list.
What are your health requirements for joining your Multi-Day Dive Tours?
As with any dive tour – or indeed any dive – anyone who´s reasonably fit and healthy is usually good to go diving. In case you´re not sure we suggest to consult a (dive) doctor for a check-up before booking a dive tour. At any rate, you will be asked to sign a medical statement and liability release whereby you take responsibility for your own fitness to dive.
My partner doesn´t dive. Can she join me on a multi-day dive tour in Iceland?
Given Iceland´s extreme – and extremely beautiful – nature, we go to great lengths to provide our guest with as many opportunities as possible to sightsee along the way. (That´s also because we are ourselves constantly taken aback by the beauty of this country:-) All our multi-day dive tours include a considerable amount of scenic stops, photo-ops, and travel between dive sites in through stunning landscapes. That said, at the end of the day these are dive tours and it becomes a question of how happy your partner is doing other activities (where available) or just sitting or walking around while we do our dives. In the past we have had many non-divers on our multi-day dive tours who have enjoyed themselves as much – if not more – than their diving partners, including an entire 10 day dive tour with 2 divers and 6 non-divers!
Can I still join your Multiple Day Dive Tours or Dive Expeditions if I haven´t dived in a long while?
Depending on your previous dive experience and level of dive training, if you haven't dived for a period of six months or more and are feeling a little rusty, we would suggest you do a refresher dive course prior to departure. While Iceland is known for it´s crystal clear and calm fresh water dive sites, some of our dive sites are deep, others have strong currents or sometimes low visibility. Those are the reasons we usually do require that our divers have a minimum of 4-10 logged dry suit dives and a total of 30-40 logged dives, depending on the dive tour.
What clothes do I need to bring on a multiple day tour?
Appropriate clothes. In Iceland you need to be ready for the whole range of weather, certainly bring warm clothes and something for when it rains. Don´t forget your hiking shoes and long underwear plus thick wool socks.
What size / type of SCUBA tanks do you use?
We use steel tanks due to better buoyancy properties. We use both 12 liter and 15 liter bottles. We can also offer both single and double valves. Please let us know in advance which tank configuration you require for the equipment you bring, so we can have it ready for you.
What type of valve/fittings do you have on your SCUBA tanks?
All our tanks have DIN fittings. If you bring a regulator with a Yoke fitting, also known as INT, we can bring an adapter to screw into our DIN valve. Please let us know in advance.

Other Day Tours

How long is the cave?
We use 2 different caves on this tour, depending on the time of year and weather / road conditions. Gjábakkahellir cave in Thingvellir is 360 meters long and Leiðarendi cave in Reykjanes is 880 meters long.
How long are we in the cave for?
We are usually underground for 45-60 minutes, depending a bit on the speed of the group.

Snorkeling Silfra

Can I bring my Go Pro or my waterproof camera on tour?
You are free to take your own photos or video on tour with us, with a go pro or any other camera in an underwater houseing. However we kindly require that your equipment is attached to your body in one way or another, for example with a wrist band. Many of our customers have taken their go pro’s snorkeling and diving without problems related to the cold water, but if your photography equipment comes with instructions of how deep and/or cold you are allowed to take it underwater, we strongly encourage you to follow them thoroughly.

Do you offer photos of this Snorkelling Tour?
If you would like to get high resolution under water photos of your Snorkeling Tour, please let your guides know when you meet them. You can then purchase the photos from your guide after the tour.  These pictures are a great souvenir of this extraordinary adventure. Please be aware that we can't always guarantee the photo service. Unfortunately cameras can malfunction and sometimes the guide has other priorities than taking photos. The photos of your Snorkeling Tour plus a "Best of Silfra folder" will be made available to you in high resolution via Dropbox after the Snorkeling Tour. The price for this photo package is ISK 2.990,- additional to the Snorkeling Tour price.
Do you see any life in Silfra?
No, not really. Silfra is a scenic dive and even though there are plenty of fish in Thingvellir lake, we hardly see them in the Silfra fissure itself.
Do I need to be able to swim in order to take part in Snorkeling?
Yes, you do. Even though the dry suits are very buoyant and keep you afloat we have made it a prerequisite for our snorkelers to be  able to swim and feel comfortable in water. This is for your own safety and comfort, as well as the guides' and the rest of the snorkelling group's safety and comfort.
Are the dry suits very tight / uncomfortable?
We use top quality equipment for our Snorkeling and Scuba Diving tours. The dry suits only do a certain amount of dives / time before they get sold and replaced by new ones. This ensures that our guests will always dive/snorkel in top notch dry suits frequently tested, serviced or replaced.

The same can happen on snorkelling tours if the guides evaluates that members in the group need help in the water.
Will I get wet when diving or snorkelling?
When diving or snorkelling in a dry suit, you will generally keep dry and warm. We use BARE dry suits and undergarments of the highest quality and have over 50 of them in all standard and non-standard sizes. Our rental dry suits do only a certain amount of dives before they are sold and replaced with new suits. They are inspected after every tour to assure a minimum of possible failure. However, dry suits are often custom-made to fit each and every individual. This is especially the case with regard to the wrist and neck seals sizes. Even though we do our very best to prevent it, in rare occasions it does happen that someone gets wet.
How cold is the water in Silfra?
The water temperature is 2-4°Celsius all year around. This converts to 35-39°Fahrenheit.
