Why dive here
With 35+ marine species recorded in the area - including humpback whales, orcas and seals & sea lions - Keystone Jetty offers some of Pacific Northwest's richest reef diving. Water ranges 7-17°C, warmest July, August, September.
Keystone Jetty is a solid shore dive in the Pacific Northwest, perfect for divers comfortable with a bit of a current. You'll likely spot giant pacific octopus lurking in the rocks, alongside wolf eels peering from their dens. It's a great spot for getting your cold-water skills honed, or for a relaxed Sunday dive if you know the tides. We find it suits photographers and macro enthusiasts particularly well.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
