Roller Reef
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Roller Reef offers some of Alaska's richest reef diving. Water ranges 5-15°C, warmest July, August, September.
Roller Reef, off the coast of Alaska, offers a surprising glimpse into cold-water reef systems. We've found the corals here hardy, clinging to the rocks and providing shelter for a variety of northern species. It's a site best suited for experienced drysuit divers keen to explore the unique ecosystems of the North Pacific, often battling strong currents. Expect to see wolf eels peering from crevices and substantial aggregations of rockfish.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
