Black & Blue - Silfra Snorkeling + Lava Tunnel

This Iceland snorkeling and caving tour allows you to experience the country from a new angle.

We start a day with the black part of the tour by exploring a lava tube cave close to Reykjavík. We'll head to Raufarhólshellir, one of Iceland's longest lava tube caves. This adventure gives you great insight into the volcanic activities that have formed the country.

After caving, you will have a chance to grab some lunch between the two activities.

Next, we'll meet you at Þingvellir National Park (Thingvellir), where the Silfra fissure is found. Here we will put on our dry suits and get ready to explore the blue. Witness some of the clearest water on Earth as your guide leads you on a fascinating underwater journey.

Participants need to be comfortable in the water and be able to swim. You cannot participate if you are pregnant due to the small risk of cold water entering the suit.

To participate in the tour, you must read and sign the medical statement form in our Snorkeling Handbook before booking. If you have any medical conditions, medical approval from a doctor is required.

Dry suit sizes: While we would like everyone to join our tour, our gear sizes reflect what is available on the market, and it is important guests are within the size parameters. This ensures the safety equipment can serve its purpose and keep guests from getting cold in the glacial water.
