  • Fins, made by Poseidon, Apeks,  or Mares. Made of rubber for diving or rubber or plastic for snorkeling.

Good to know

The Suit: The dry suit has tight seals on the neck and wrists that stop water from getting in, which is what you want when diving in glacial water. If you are claustrophobic, tight seals might be a bit uncomfortable, however, do not book the suit bigger than your actual size, as it won’t seal tightly and we will not have a replacement on site. 

You will get wet: participants wear a hood and gloves made of neoprene, a different material than the suit, so your head and hands will get wet under water.

Weather and water: water in Silfra is at 36°F – 39°F (2°C – 4°C)  and originates in Langjökull glacier about 50 km away. Outside temperatures in Iceland can be quite cold too. You will spend up to 5 hours outside on a diving tour so dress accordingly and make sure you have warm thermals, winter coat, hat and gloves during the winter.

Safety Disclaimer: be aware that Diving at Silfra has its own inherent risks and safety measures are treated with the utmost respect. When you join the diving tour, you may be requested to sign an additional liability release. We advise you to listen to your guide’s instructions and behave in a responsible manner. Those tourists who have no prior diving experience are advised to snorkel Silfra instead. Our guides reserve the right to refuse participation to any customer who they believe will not be able to complete the tour because of their physical condition, injury or illness. In such cases, full cancellation charges apply.
