Protected Area
Sawmill Bay
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Bligh Reef offers some of Alaska's richest reef diving. Water ranges 5-15°C, warmest July, August, September.
Bligh Reef isn't your typical coral reef; think cold water and rugged beauty. We've often spotted Orcas cruising the surrounding waters, and the nooks of the reef hold giant octopus. It's a raw, wild place best suited for experienced divers comfortable with unpredictable Alaskan conditions. If you're after something truly different, Bligh offers a stark, memorable dive.
Safety Notes
