About Arachne Reef

Arachne Reef is a boat-access cold-water reef in Boundary Pass with a shallow top and abrupt drop-offs on every side. The site rewards a controlled boat drop timed to slack or near-slack water, because current can build quickly. Expect a classic Pacific reef profile with octopus, crab, rockfish, and other hardy cold-water life.
