HMS Majestic - Alonissos Marine Park
McKay Reef, up in the Pacific Northwest, offers a classic cold-water dive. We’ve seen it when the visibility really opens up, allowing for good views of giant sunflower stars spread across the rocks and Dungeness crabs scuttling into crevices. You'll likely spot schools of shiner perch darting between kelp stalks, and sometimes, if you're lucky, a big skate gliding by. It’s a solid dive for those who appreciate the unique, rugged beauty of the region’s cooler waters.
