What You Can Expect

Day Trip from Reykjavik Small Group Silfra Snorkeling and Lava Caving Adventure

Explore the hidden underworld of Iceland's magical lava tube caves.

Following pickup at your Reykjavik hotel, climb aboard a comfortable, climate-controlled minibus for the 60-minute journey to the UNESCO-listed Þingvellir National Park. 

After a safety briefing and introduction to the area, get fitted for spelunking and snorkel gear, and then follow your guide to the lava fields under the park through Gjábakkahellir cave. Climb through a lava tube and take a 1.5-hour tour of the cave, located in one of the most active volcanic areas in the world. See shield volcanoes, products of lava flows that have left spectacular layers of rock and lava deposits over the years. Please note: In the winter, you will explore Leiðarendi cave.

Before continuing on to Silfra, take a break for lunch (own expense).

At the Silfra fissure, slip on your snorkeling gear and explore the underground pool. Drift between the tectonic plates that separate North America and Eurasia, and check out the most scenic areas of the pool with your guide. 

After a day of exploring Þingvellir National Park, you'll conclude with drop-off back at your Reykjavik hotel.

I really enjoyed the day with people I never met- our tour guide was awesome. The Lava exploration was tricky but my new friend Katrina made it enjoyable. Our tour leader assisted when required in the Lava Caves. Amazing what is underground - tunnels and rock formations are something to experience!
The snorkeling was just simply amazing as well. Simms was the tour guide and assisted in every aspect - challenging getting into a dry suit for the first time I am a little fluffy but the rewards on snorkeling was worth the efforts! I cannot explain the feeling of the adventures - Amazing
