Cow and Calf

Cow and Calf Rocks is a rocky dive site off St. Thomas, in the U.S. Virgin Islands, suited to beginners and intermediate divers. The site sits within a protected marine park and features an intricate network of wide swim-through tunnels and a large archway formation known as "The Cathedral," where light streams down through the rock to the reef below. A notable feature called the "Champagne Cork" swim-through gently carries divers back out onto the reef. Maximum depth is about 40 ft (12 m), with the shallowest areas around 25 ft (8 m), making it accessible for a wide range of experience levels.

Marine life at Cow and Calf Rocks includes schooling French Grunts and Caribbean Reef Squid sheltering among the rock formations, with the site described as holding an abundance of reef fish throughout its tunnels and archways.
