    Edmonds Underwater Park, or "EUP" as we often call it, is a genuine standout in the Pacific Northwest. Forget about sun-drenched reefs; here, it’s about the hunt, the thrill of spotting something extraordinary in the murk. We love the quirky, cold-water critters that call this place home. Descend into the kelp and you’ll find giant pacific octopuses tucked into crevices, their eyes watching you with unnerving intelligence. Look closely on the pilings and you'll spot nudibranchs, particularly the striking Puget Sound King Crab. Our favourite time to dive EUP is during a high slack tide, preferably on a sunny weekend morning when the light penetrates just enough to make the anemones glow. You’ll weave through artificial reefs, old boats, and even a sunken dock. Keep an eye out for the resident wolf eels, they're surprisingly personable once you get to know them. The park can get busy, especially the closer parking spots, so we'd suggest arriving early. It’s a site that rewards patience and a keen eye, perfect for photographers and anyone who loves discovering the unusual.
