Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Pleasant Island Reef offers some of Alaska's richest wall diving. Water ranges 5-15°C, warmest July, August, September.
Pleasant Island Reef offers a glimpse into Alaska's cooler waters, with a focus on larger marine visitors. We've often spotted Gray Whales migrating past, and Orcas are a frequent sight, sometimes even Common Seals. While the coral reef itself isn't the star, it provides a backdrop for observing these powerful creatures. It's a spot for patient divers who prefer watching big animals to intricate reef scenes.
