Bubbling Sands Snorkeling Tour in Iceland

Discover one of Iceland’s hidden gems on the Bubbling Sands Snorkeling Tour in Litlaá, also known as the “Little River.” Located near the northern coast of Iceland, just south of the Arctic Circle, this geothermal river offers a unique snorkeling adventure unlike anywhere else in the country.

Litlaá was formed in 1976 after the Krafla volcanic eruptions. Warm geothermal springs mix with colder water from nearby Lake Skjálftavatn, creating a comfortable snorkeling temperature of 12–17°C year-round. Unlike most rivers in Iceland, Litlaá is shallow with a gentle current, more like a lagoon, making it safe and enjoyable for snorkelers of all levels.

What makes this river truly magical are the bubbling volcanic sands at the bottom. Heated water rises through the sediments, creating mesmerizing patterns and ripples beneath you as you float along. Mixed with the sands are bright green algae fields and abundant snails, which have earned the lagoon the nickname “Snail Lagoon.” Litlaá is also one of Iceland’s top trout rivers, so you may spot fish gliding through the clear waters.

This adventure is part of the famous Diamond Circle sightseeing route, just 30 minutes from Húsavík (Iceland’s whale-watching capital) and close to Ásbyrgi Canyon. Other nearby attractions include Goðafoss waterfall, Dettifoss waterfall, and Lake Mývatn, making this snorkeling experience a perfect addition to your North Iceland itinerary.
