Inside the Cove: The sheltered water inside the cove. Waves are small here, but sediment that washes in tends to stay, so it often reads murkier than the water outside.

Outside the Cove: The water just past the mouth of the cove, along the reef and kelp. Most of the diving happens here, and it is the number the page headlines.

Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

About Two Harbors

Two Harbors is the other town on Catalina, a small village at the Isthmus on the west end of the island where the land narrows to about half a mile between Isthmus Cove on the front side and Cat Harbor on the back side. The year-round population is around 200. The village has one general store, the Harbor Reef restaurant, a dive shop, a campground, a small kayak rental, and a sailboat anchorage. Everything closes early. The Catalina Express runs a separate ferry line from San Pedro, the Safari Bus crosses the island from Avalon, and most Catalina locals reach the village by private boat.
