Oktopusas - Bornholm
Harrison Reef in Alaska offers a glimpse into a very different kind of cold-water diving. While we don't have hard data on depth or difficulty, our team found the conditions here to be typical of Alaskan shore dives – expect chilly water and prepare for a bit of a current. The real draw is the unique collection of North Pacific life; we’ve spotted Calico and Coho salmon, and the kelp forests often hold Red Rock and Dungeness crabs. Keep an eye out for the Common Loon or Marbled Murrelet diving from above. It’s a great spot for divers keen on temperate marine biology and a quiet, uncrowded experience.
