Why dive here
With 35+ marine species recorded in the area - including humpback whales, orcas and seals & sea lions - Spring Bay offers some of Pacific Northwest's richest reef diving. Water ranges 7-17°C, warmest July, August, September.
Spring Bay. Ah, Spring Bay. If you’re looking for a quiet, introspective dive that still delivers, this is it. We often head here when the more famous spots are choked with boats. Drop in and you’re immediately enveloped by the gloom, which sounds ominous but actually lends a real sense of adventure. The real stars here are the shrimp, not the flashy nudibranchs or big fish. You’ll find Alaska shrimp, sidestriped shrimp, and ocean shrimp tucked into every crevice, plus the spindly four-spined squat lobsters clinging to the holdfasts. Keep an eye out for the pale moonsnails, they’re surprisingly elegant. The eelgrass beds here are some of the healthiest we’ve seen, swaying gently and providing perfect cover. It's a site that rewards slow, deliberate diving, perfect for macro photographers or anyone who just wants to get lost in the details.
Safety Notes
