Diving by country

What is diving in Cold Water like?

Cold-water diving trades warmth for things the tropics cannot offer. Silfra in Iceland is a rift between two tectonic plates with visibility in the tens of metres, snorkellers swim alongside orca pods hunting herring in the fjords off Skjervøy, and divers go beneath icebergs with penguins and leopard seals on the Antarctic Peninsula. Water here runs from below freezing to around 20 °C.

Britain and northern Europe are wreck country. The German battleships scuttled at Scapa Flow in 1919 still lie on the seabed, the Rondo in the Sound of Mull stands almost vertical from 15 m to 50 m, and the brackish water of the Gulf of Finland keeps three-hundred-year-old ships standing with their masts up. Grey seals are the other draw, approaching divers at the Farne Islands and following them around Lundy Island.

Best diving in Cold Water for wrecks, big animals, beginners, macro and liveaboards

One destination per theme, picked from the species, dive types, access and site records on each destination page.

When is the best time to dive Cold Water?

The busiest stretch is July–August: in August, 47 of the 97 destinations here are in peak season.

The leanest months are April and November, when Lago Nahuel Huapi & Bariloche and Stockholm Archipelago & Dalarö are still at their best.

Gothenburg Archipelago, Gotland & Fårö, Gulen & the Sognefjord and 17 more rate good or better in every month.
