Although we understand that many people prefer to snorkel with a full face snorkel mask (also known as a Easybreath mask or Ninja mask), it is regrettably not possible to use them here in Iceland as it is not possible to get them to seal around the hood that you need to wear. This would result in your mask constantly flooding with water, which would not be an enjoyable experience

We advise that you bring gloves, at all times of the year, to keep your hands warm before you get in and warm them up after you get out of the water. This is especailly important in winter. However, whilst in the water, you will be wearing neoprene mittens that we provide for you.

Unfortunately we do not offer prescription masks, due to the amount of prescriptions we would need to cover. If you use glasses we recommend that you bring contact lenses as the glasses do not fit under the mask. If you do however own a prescription mask, you are of course welcome to use it on the tour.

Unfortunately, we do not offer any life jackets on our tours. All our participants must be able to swims and feel comfortable in water.

Unfortunately we do not offer cameras for rent, we do however offer a very reasonably priced photo package including photos taken by your guide during your tour, and access to our "Best of Silfra" collection. You are however welcome to bring your own waterproof camera.

The photo package can be paid for with either cash or debit/credit card, on site with your guide. If you decide at a later date that you would like to purchase the photos you can contact our office and a payment link will be sent to you, allowing you to pay online.

We are usually underground for 45-60 minutes, depending on the speed of the group.

During our snorkel tour we are in the water between 30 and 45 minutes, depending on the speed that the group travels and how long they want to explore in the lagoon at the end.

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.

Unfortunately it is not possible to wear glasses underneath the dive mask, as the mask would fill with water. We therefore advise that if you are near-sighted (i.e. you need glasses for distance), that you consider wearing contact lenses or bring your own prescription mask with you. If you are snorkelling and have prescription swimming goggles you are able to wear them, but you must also bring a nose clip to close of your nose, so that you are able to use your snorkel. If your prescription is not very strong (up to approximately -4) you may find that the natural magnification of the water will still allow you to see quite clearly. Should you need to purchase contact lenses, there are several opticians in Reykjavik where you would be able to do so.

We offer hot chocolate, tea and cookies after the dives and snorkels, but do not provide any other form of food. There is also drinking water on site. You are however welcome to bring your own food and drink with you and are allowed to consume it in our vehicles. We kindly ask that you have eaten breakfast/lunch before your tour, as you will need the energy it provides. If you have not had a chance to do so, please let our guides know when you are picked up and they can make a stop at a convenience store so you can pick something up.
