Hot Spring Snorkeling and ATV

Swim in a glass of champagne, drive through the lava fields

Hot springs & Lava fields

This tour offers a once-in-a-lifetime opportunity to observe how the power of the Earth has shaped Iceland through the centuries!

This is a selfdrive experience, we will meet your at Seltún - Krísuvík and drive you to the unique Lake Kleifarvatn. The drive from Reykjavik is only 30 minutes, but you will feel like you have landed on another planet. The black sand beach where you will gear up for your snorkeling tour is a great feature itself, but it is nothing compared to the scenery you will find once you look under the surface of the lake.

At first you will see the white and yellow sulfur deposits and the beautiful designs they draw on the bottom of the lake. As we swim farther from the shore, the environment will start changing around us. That's when you will see (and feel!) the gas bubbles emanating from the lake's floor. Now you will be swimming in an actual caldera, something you can only do in Iceland! The feeling has often been described as "swimming in a glass of champagne".
After the snorkeling tour, you will get out of your gear and enjoy some light refreshments on the shore of the lake.

At this point we will make our way to the Seltún geothermal area, where we will walk among the boiling mud pots and observe the mesmerizing geothermal activity that characterizes the area.

After your visit of the Seltún area, you will make your way to our trusted partners for your ATV tour. The drive takes your through historic lava fields, the old harbour area of Hópsnes and its shripwrecks and old town foundations.

Immediately after this you will get to a more scenic and slightly more adventurous mountain track toward the peak of Mount Hagafell. The peak offers a spectacular 360° view over the blue Lagoon, the Svartsengi volcanic crater formations, Mount Fagradalsfjall, Eldey island and more!

At the end of the ATV drive you have an option to end your day with a relaxing visit at the Blue Lagoon (entrance fee not included). as the ATV tour is located about 5 minutes from the Blue Lagoon.

If someone in your party doesn't snorkel but wants to join the ATV tour, you can book them in from this page.

Humbling, Exhilarating, Moving, Inspirational!

[...] I can only say that as soon as my head entered the water and my eyes and breathing adjusted, I was in a completely different and totally magical world of wonder and breathtaking beauty! There are not enough words to explain how awesome this gorgeous place is, this hidden and unexpected wonder that lies beneath the surface and between the tectonic plates; the rifts, cliffs, the vibrant and unexpected colours, everything about beautiful Silfra was truly remarkable! We were advised that too many facial expressions were not a good idea as they allow water to enter your face mask, but I could not stop smiling!! It was something that I will remember for the rest of my life! Once we'd reluctantly dragged ourselves out of the water, we made the short walk back to the van to get changed back into our clothes, and were rewarded with hot chocolate and cookies, and very well received they were too! I would absolutely recommend this fabulous adventure to everyone, but please be mindful of the instructions they give you. You WILL need long thermal underwear for extra warmth, even though you are given a base layer for under the dry suit. You WILL need extra thermal socks (I wore 3 pairs!) and you Will need to be confident in water because this isn't just any old snorkel. For an experience of a lifetime, contact this great company and enjoy every single bit of it!
