    StandoutDramatic pinnacle topography

    Dyer Rocks isn't your average Pacific Northwest dive. It's a proper pinnacle, rising from the depths, and the current can really rip here, so pick your slack tide window carefully. When it's calm though, it's one of our favourite spots for a reason. The walls are just covered in life; think massive colonies of sunflower stars crawling over every surface, and the most vibrant green sea urchins tucked into crevices. We’ve seen California spot prawns hiding in the cracks, their eyes glinting in the torchlight, and the roughpatch and horned shrimp are everywhere if you slow down and look closely. We love the feeling of being out in the open, even if it's only a boat ride from shore. Keep an eye out into the blue; we’ve had dogfish cruise past us here, and while rare, Orca have been sighted on occasion. This is a dive for those who appreciate the robust, unapologetic beauty of cold-water ecosystems and don't mind a bit of a current for the reward. It’s a site that feels wild and untamed, offering a glimpse into the raw power of the Pacific.
