Hot Spring Snorkeling Tour

Snorkel Above Geothermal Bubbles in a Volcanic Lake

Hot Spring Snorkeling

Where few have been before

Snorkeling in bubbling hot springs is usually impossible as the water is far too hot, but the hot springs at the bottom of Lake Kleifarvatn provide us with the opportunity to do just that. Lake Kleifarvatn lies in stunning volcanic landscape just 30 minutes outside of Reykjavík and only 20 minutes from the active volcanic area in Reykjanes peninsula. Talk about a unique tour!

This selfdrive tour starts at Seltún, a nearby high temperature geothermal area on land. In Seltún we will walk along the boiling mud pots and colorful sulfur deposits. Your guide will tell you about the area you are in as well as brief you on the snorkeling tour and Kleifarvatn.

Standing at the lake shore and changing into your dry suit, you will probably catch a whiff of the sulfur emitted from nearby hot springs and the total silence will let you forget that you are anywhere near civilization.

The underwater hot springs in lake Kleifarvatn have only recently been discovered and are about a 150 meter swim from the shore. Upon entering the lake you can see the white and yellow sulfur deposits on the lake floor. When we swim closer, you’ll begin to sense the environent around you changing as you approach the gas emanating from below the lake’s floor.

When you get to the hot spring area you will be able to snorkel directly over bubbling calderas. We’ve heard this sensation described as similar to ‘snorkeling in a glass of Champagne’—the fact that you are snorkeling in a caldera is also impressive enough!

When back on land we will enjoy some bubbling refreshments at the shore.

Glittering pearls in lake Kleifarvatn

We have been travelling to Iceland for several years and were looking for a special experience to get a little closer to the land of fire and ice. The choice fell on the snorkeling tour in lake Kleifarvatn - and we were not disappointed! There is something very special about snorkeling in a lake that lies in a volcanically active zone. Our guide Ramiro was just great - he explained everything to us and gave us a lot of knowledge about the area and the lake. The underwater world of lake Kleifarvatn is simply amazing - hot springs are bubbling at the bottom, and the countless air bubbles give you the feeling of swimming through a curtain of glittering pearls - a really special experience :)
Thanks again to Ramiro - he took a lot of time for our questions and took good care of us. We would book the tour again at any time!
