Mallard Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Mallard Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Mallard Rock gives you a real taste of Alaskan diving. It’s a rocky spot, with visibility that can swing from 5 to 15 meters depending on the day and the plankton blooms. We’ve seen red salmon and coho pushing through here, especially during migration season, and the Giant kelp can be really impressive, forming dense underwater forests where you can spot Big Skates resting on the bottom. Look closely in the nooks and crannies for Prickly sculpin and the occasional California Spot Prawn. It's cool, temperate diving, often with some current, so it’s best for divers comfortable in colder water and a bit of a push.
Safety Notes
