Why dive here
With 35+ marine species recorded in the area - including humpback whales, orcas and seals & sea lions - Henderson Point offers some of Pacific Northwest's richest diving. Water ranges 7-17°C, warmest July, August, September.
Henderson Point is a sleeper hit for us. It’s not flashy, but it’s reliably fascinating and we often find ourselves lingering longer than planned. The site drops off gently, making it really accessible for newer divers, though experienced eyes will pick out plenty of intrigue. We love the sheer variety of life here. You’ll weave through eelgrass beds, feeling the cool water shift around you, eyes peeled for those camouflaged Slender Sole flattened against the sandy bottom. Keep an eye out for Red Rock Crabs scuttling between rocks, and we've had some memorable encounters with giant octopuses tucked into crevices – always a thrill. Dive this during a slack tide, if you can. The currents here can push you around a bit, especially when the deeper water starts moving. You’ll want time to really slow down and appreciate the smaller stuff, like the delicate Star ascidians clinging to the rocks or the way the Pacific Glass Shrimp almost disappear against the silty bottom. This is a site for the patient observer, someone who enjoys finding the beauty in the subtle rather than the spectacular.
