Testlatlints Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Testlatlints Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Testlatlints Rock might not be on every diver's radar, but for those who make the journey to Alaska, it offers a real taste of cold-water diving. The rocky reef here is draped in a surprising density of red soft corals, creating a vivid contrast against the often-grey Alaskan light. We've spotted massive sunflower stars clinging to the rocks, alongside the peculiar Spotted Ratfish gliding past. Keep an eye out for the resident Big Skates, too. It's a site that appeals to divers keen on unique invertebrates and a bit of wild solitude.
