About Strýtan - geothermal cone

Strýtan is a diving spot in the North of Iceland, located in the beautiful Eyjafjörður. We go out from a small town called Hjalteyri which is just out of Akureyri, the capital of North Iceland. Strytan is a totally unique dive site, as it is the only known underwater hydrothermal vent in shallow enough water to dive it. This geothermal cone rises the 70 meter deep seafloor and streches all the way up to 15 meters, making it accessible for recreational diving.

Strýtan was only discovered in 1997 but it has been in formation for over 11.000 years. When the hot water from the vent comes in contact with the cold ocean minerals precipitate and cones of magnesium and silicate are formed. So in a way Strýtan is still beeing formed since about 100 liters of water are gushing from it every second.

The limestone chimney is the home of various species that only thrive in these special circumstances making this diving place extraordinary. Large groups of cod and pollock are commonly seen. The star of the show is the friendly wolffish Stephanie! This dive site if also good for macro like nudibranchs and shrimps, and there is plenty of cold water soft corals to observe.

The top of the cone sits at 15 meters, and the bottom is about 70 meters deep. Visibility ranges from 5 – 20 meters depending on season, tide and weather. It is a 15 minutes boat ride to get to Strytan, and you will be diving from a RIB.
