About this activity

This adventure starts with the black as you explore the hidden world of the lava field underneath the Thingvellir National Park. The park is located in the tectonic rift valley between America and Europe and is also filled with incredible lava caves. On this trip you will explore an Icelandic cave and discover the marvels that volcanic activity has created in the past. The 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 exploration you will have time to grab lunch before moving on into the blue for your second adventure...

Part two of this trip includes snorkeling in the Silfra Fissure, an otherworldly scene that is world famous for its heavenly shades of blue. The crystal clear water in the deep fissure gives you a feeling of pure weightlessness as you venture down the lazy current. The snorkeling is a relaxing yet exotic trip in an unbelievably beautiful environment between the two Eurasian and North American tectonic plates.
