Tanu Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Tanu Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Tanu Rock is a pretty typical Alaskan shore dive, offering a solid slice of the local temperate water experience. The rocky substrate here is home to a surprising number of invertebrates, like sunflower stars and those big green sea urchins, which we always enjoy spotting amongst the giant kelp. You’ll also likely see a few different salmon species, depending on the season, and sometimes we’ve been lucky enough to spot schools of Pacific herring moving through. It's a reliable dive for getting a feel for the region’s cooler waters.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
