Itinerary

Day 1: Raufarhólshellir Lava Cave

Our adventure starts with the black as we explore the hidden world of the lava field under the Þingvellir National Park. The park is located in the tectonic rift valley between America and Europe and littered with quirky, interesting lava caves. Walking down into a cave and discovering the marvels that volcanic activity has created in the past is a trip that everyone can do. The Raufarhólshellir cave is a perfect example of an Icelandic lava tube and is situated in one of the most active volcano areas in the world. After the cave you have time to grab lunch before moving on into the blue and your second adventure.

Day 1: Silfra Fissure
Snorkeling in the Silfra fissure is our second adventure. The Silfra fissure is one of Iceland’s best-kept secrets, an otherworldly scene that is world famous for its heavenly shades of blue. Frequently rated as one of the worlds top ten dive sites, the Silfra offers up to 100 meters of underwater visibility. The crystal clear water in the deep fissure gives you a feeling of being weightless as you float down with the lazy current.  The snorkeling is a relaxing but exotic trip in an environment most will only encounter in their dreams.
