San Juan County Park is nice, but Limekiln Lighthouse State Park is exceptional. Park in the lower lot and use a wheelbarrow to tote your gear 0.15 mi. down a gated road to a picnic table at the lighthouse. Entry is a small crevice immediately left (south) of the light. When the kelp isn't heavy this is an amazing dive. You'll get cold from not moving around much because there is so much to see. Best done at slack or during ebb tides with low exchange, because southerly currents hit the point and move away from shore, swirling clockwise in the small bay south of the point. 40 min after exiting on my last dive, Orcas were in the small bay. Watch for container ships in Haro Strait, they can kick up a few (short lived) rollers. This is the dive on the cover of Northwest Shore Dives. It may spoil you!
