Hi tkaelin,
This was the first time I had been down to this spot, and the first time my son had been in the water since October, so we had a very conservative plan. Parked in Lot #2. It's a short walk across the grass and down the embankment to the small cove with the little pebble beach. The slope is fairly steep, but not too bad, just watch the loose rock that is all over. I had heard that the best diving is within 50 yards of the beach, so that's pretty much where we stayed. Underwater, the topography is very similar to above - rocky with some neat ledges, shelves, overhangs and some cool swim thrus. The was not much current, as we dove the high slack, but the was a good amount of surge. Temp was 64, and viz was 6-8feet. We basically just swam around the cove we splashed in and the areas just north and south of the entry point. I don't think we ever got more that 75 yards from shore. Most of the cool stuff was close in. Lots of bass and tautogs, some sea stars, and a few tiny lobsters. Plenty of colorful seaweed and other plant life. It was a nice dive! Much easier to park than Cape Ann.
