Ten Mile Point. Now this is a spot we keep coming back to. Forget those stories about the Pacific Northwest being all gloom and low visibility. On a good day, and you do need to pick your days here, Ten Mile Point offers something truly special. We love the drift along the wall, usually starting north and letting the current carry you. Keep your eyes peeled for those sneaky Snake Pricklebacks tucked into crevices, their bodies almost camouflaged against the rock. What really sets it apart for us are the invertebrates. You'll often find Horned Shrimp clinging to the hydroids, and if you’re patient, the elusive Arctic Eualid Shrimp can be spotted too. It’s a macro photographer's dream, honestly. We’ve spent entire dives just hovering, watching Red Rock Crabs scuttle across the seafloor, or finding tiny California Spot Prawns tucked into anemones. The kelp forests sway gently, filtering the light into ethereal shafts, and when the light is just right, the whole place shimmers. It’s a dive that rewards slow exploration and a keen eye, perfect for divers who appreciate the subtle beauty of temperate waters.
