Snorkel through lava filtered water and walk where lava flowed

Our Silfra Snorkeling & Lava Caving Tour is a great combination tour for those who want to make the most of their time in Iceland.

On this trip you will get to snorkel through one of the world’s most fantastic snorkel and dive sites, Silfra, as well as go hiking through a lava tube that was created thousands of years ago by a river of red glowing lava.

Depending on the time of year and the weather, we will choose either the Gjábakkahellir cave in Thingvellir or the Leiðarendi cave, which is closer to Reykjavik.

Both caves are lava tubes that display the same typical features of this most common type of lava cave in Iceland.  The caves are full of utterly weird and wonderful rock formations as well as a splattering of amazing colors.

Please make sure to bring good shoes, as we will walk over very uneven ground.

Even though at some points inside the cave we will have to climb and crawl a little, this cave tour is an easy one that can be undertaken by everyone who feels comfortable in confined spaces and is fit to take a short hike.

You can read more about the Silfra snorkeling tour here.

Note that snorkelers and divers can join on the caving portion of the tour together.

Frequently asked Questions

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.
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.
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.
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.
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.
What dive/snorkel equipment do you use?
Please read details about our dive equipment on our equipment website.
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.
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.
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.
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.
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.
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.
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.
