During my first dive in the cove, I thought that my fins were repeatedly getting caught in the kelp; turns out, there was a playful harbor seal nipping at them, and I missed it! My favorite dive of the two is Otter Cove. There is a great canopy of kelp over the rock 'reef' in 40-50 feet (you have to swim a ways to get there). Huge biodiversity here. Harbor seals, diving cormorant birds, sea lions, sea stars, kelp crabs . . . Great dives when there's no South swell.
