Snorkeling in the Silfra fissure, a fresh water spring located in a crack between the continents of North America and Europe and explore the underground treasure of a lava tube cave.

We pick you up from your accommodation in Reykjavík and then head for the cave where we will start our adventure. We have two lava tube caves that we can choose between depending on the season and conditions; Leiðarendi and Gjábakkahellir. Both caves are classic lava tubes that display all the typical lava tube features; splash and shark tooth stalactites, drip stalagmites and lava falls.

After the caving part, we make our way to Thingvellir national park, the home of Silfra fissure. Before we jump in the water, we gear up with dry suits and get a safety briefing from the snorkeling guides.

Once in the water, the slow current takes you gently through the fissure while you take in the otherworldly beauty displayed in the crystal clear water. You will spend about 40 minutes in the water and the dry suit, as well as the teddy bear suit, will keep you warm and dry in the approximately 3°C cold water.

After a full day of excitement, we drive back to Reykjavík where we expect to be around 5-6 pm.

Snorkeling in Silfra Fissure
As well travelled adventurers, we had an amazing, unique experience snorkeling in Silfra. The guides were very informative and helpful with our wetsuits. We felt completely safe, despite the freezing water. The water was crystal clear with perfect visibility all the way to the bottom. Definitely worth taking the GoPro. An experience of a lifetime.
