Parson's Landing is a protected Catalina cove with beach camping, shoreline snorkeling, and relaxed shore diving once you get there. The cove sits on a sand-and-gravel beach with rocky edges to either side, so it feels more like a secluded island camp than a technical dive. The tradeoff is access: you usually hike, kayak, or arrange a boat arrival, but the payoff is calm water and a classic Catalina backcountry feel.
