Winnifred Rocks
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Winnifred Rocks offers some of Alaska's richest wreck diving. Water ranges 5-15°C, warmest July, August, September.
Winnifred Rocks offers a solid Alaskan dive, a rocky site that won’t blow your mask off but delivers some fascinating smaller finds. We’ve found the real stars here are the invertebrates – think sunflower stars sprawled across the rocks, four-spined squat lobsters tucked into crevices, and the delicate fronds of northern sea ferns swaying in the gentle surge. Keep an eye out for spotted ratfish cruising the edges, their distinctive profiles always a treat. It’s a good spot for a relaxed exploratory dive, especially if you’re keen on macro life and enjoy the cooler water environments.
