Benson Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Benson Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Benson Rock offers a quintessential Alaskan dive, raw and invigorating. We’ve found decent visibility here, especially in the calmer summer months, letting you really appreciate the rough-hewn rock structures. Keep an eye out for the big skates gliding across the seabed and the ubiquitous red rock crabs scuttling between crevices. It's a solid dive for those who appreciate colder water, a bit of adventure, and want to see some serious Pacific Northwest species in their natural, rugged habitat.
Safety Notes
