    Mouat Reef is exactly what we picture when someone says "Pacific Northwest diving" – a real kelp forest adventure. We love dropping in here, particularly on a sunny afternoon when the light filters down through the canopy. The sheer volume of shiner perch is always astounding, a shimmering curtain that sometimes feels so thick you could swim right into it. Keep an eye out for blackbelly eelpouts tucked into the crevices; they're masters of camouflage, but rewarding to spot. What makes Mouat special isn't just the resident critters, but the seasonal visitors too. Watching pink salmon push through the kelp in late summer, with spiny dogfish cruising alongside them, is an unforgettable show. We've even been lucky enough to see common seals darting through the fronds, sometimes seemingly just playing in the currents. It’s a site that rewards repeat visits, always something new happening.
