Litlaá, meaning “Little River” in Icelandic, is located near the northern coast of Iceland, just south of the arctic circle. This is an unusual place to find a 12-17°C river, but the geothermal activity keeps it a nice warm temperature.

This intriguing river was formed in 1976 following the volcanic eruptions of Krafla. The hot water comes from springs that are unusally warm. The river then mixes with colder water from the nearby Lake Skjálftavatn which makes it a very pleasant 12-17°C river to snorkel in.

The river is so shallow that it is almost like a lagoon. The current is very slow, allowing you to explore the different parts of the lagoon, making it perfect for snorkeling.

The river’s floor is full of mesmerising dancing volcanic sands and multicoloured sediments leaping from the bottom. The heated water erupts from below the bottom causing beautiful designs and ripples in the riverbed while you drift along the surface above. This has been described by the phrase "Bubbling sands" and is a sight best seen with own eyes.

Mixed in with the bubbling sands you will see beautiful fields of green algea which are mesmerising to look at. The underworld at it's best.

The lagoon has sometimes been called snail lagoon due to the number of snails living there. It is also one of Iceland's greatest trout rivers. So, you will most likely catch a glimpse of some wildlife during your snorkel.

This location is on the Diamond circle about 30 minutes from the whale-watching town of Húsavík and a short distance from Ásbyrgi canyon, making this the perfect Diamond circle selfdrive tour. Other destinations on the Diamond circle include Goðafoss (waterfall of the Gods), the infamous Dettifoss waterfall and the beautiful Lake Mývatn.
