My brother and I did two nice long shallow dives at Pebble Beach recently. Found the parking to be easy and abundant, as far as Cape Ann goes. It was a sunny warm day with a small amount of wave activity, and we dove at low tide and just after. There were lots of other divers in the water or getting ready to go in. However, we met only three or four u/w. We were lobstering and did surprising well for the popularity of the site. It's easy access and, with the amount of other divers who were also hunting, divers on both sides of us came back with 4 or 5 in their catch bag each. Viz was good with small surge. It's a long, but not impossible swim to the rocky reefs. I recommend this site for beginner and intermediate divers as well as advanced divers trying out new equipment.
