Silfra Fissure at Thingvellir National Park
The Silfra Fissure separates the Eurasian and North American tectonic plates. Diving through it is an experience not to be missed. The water clarity on this freshwater dive is unbelievable, and the experience is breathtaking. There’s no marine life; however; it’s all about the view and the experience. It’s a popular site and can be busy. In summer, it’s possible to dive it under the midnight sun.
The Silfra Fissure is around 45 minutes’ drive from Reykjavik. Expect water temperatures of 2-4°C (35-39 °F).
Arnarnesstrýtan and Strytan Hydrothermal Chimney
These are the only hydrothermal chimneys accessible to recreational divers. Hydrothermal chimneys are usually so deep that the only way to see them is in a submarine. The hot water billowing from the chimneys is 79°C (160 °F), and there’s plenty of life. Expect to see wolfish, cod, nudibranch, clams, starfish, and maybe even whales. The chimney at Strytan rises some 50m and is a sight to behold.
These sites are in the far north of Iceland at Eyjafjordur Bay, around 5 hours by road from Reykjavik.
Puffins and Guillemots significantly outnumber the human inhabitants of the arctic island. From the 1st June to 22nd July you can enjoy diving with these birds as well as plaice, pollock, and cod. Swim amongst the kelp in the impossible clear arctic water.
Grimsey Island is Iceland’s northernmost island.
Kleifarvatn is a large lake 30km from Reykjavik surrounded by colored hills and unusual lava formations. Topside the vistas are stunning and underwater hot water springs bubble. The pressure causes a vibration felt throughout your body. It’s a unique experience. In summer expect temperatures of 14°C (57 °F). You still need a dry suit to dive here.
Gardur is an ocean dive rich with algae and kelp forests which attract marine life to their nutrients. Gardur means garden which will give you an idea of the site’s richness and diversity. Expect macro critters as well as cod, pollock, herring, flatfish, monkfish, and more.
It’s an hour south of Reykjavik and close to the airport.
