Secret Harbor - North - St. Thomas & St. John
Secret Harbor – North makes for a gentle introduction to St. Thomas diving. It’s a shallow spot, topping out at 6m, which means plenty of bottom time for newer divers or those looking for a leisurely snorkel. You’ll find healthy patches of coral here, with plenty of small reef fish flitting about. We’ve seen juvenile French angelfish darting between the coral heads and a surprising number of parrotfish munching away. It's a comfortable spot to get your fins wet.
