There’s Columbia Deep and Columbia Shallow. Columbia Deep starts just after Devil’s Throat with a dramatic drop-off. Watch for large groupers and turtles. Current is usually mild here, but it’s a vast area, so you could do several dives to cover the entire area. Depth is 80-100 feet. We saw a seahorse once at about 80 feet. Columbia Shallow is only 20-40 feet deep, but it’s an incredible area with lots of coral sealife. Great area for snorkeling, too . . .but you have to get there by boat.
