Rouse Reef
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Rouse Reef offers some of Alaska's richest reef diving. Water ranges 5-15°C, warmest July, August, September.
Rouse Reef sits in the cooler Alaskan waters, a spot where you really feel like you’re diving somewhere a bit wilder. We’ve found it’s less about big pelagics and more about the intricate details. Think nudibranchs tucked into anemones and those vibrant green sea urchins clinging to the rocks. You’ll spend your bottom time cruising alongside rock walls, keeping an eye out for Red Rock Crabs scuttling past. It’s a good option for divers who appreciate a quiet dive, keen on searching for smaller creatures like the Pacific Glass Shrimp, rather than expecting a flurry of action.
