Neptune's Finger

Neptune's Finger is a wall dive site within the Cabo San Lucas Marine Park, located at Land's End where the Pacific Ocean meets the Sea of Cortez. The site consists of two coral reefs: a vertical wall and the largest sandfall in the marine park. The minimum depth is 80 feet (25 metres), with the sandfalls visible at 130 feet (40 metres) and a maximum depth of around 107 feet (32.6 metres) at the wall itself, which drops steeply into deep water. The site is protected from Pacific weather and reached by a short boat ride of around five minutes.

The reef holds a broad range of marine life. Resident species include turtles, groupers, machetes, goatfish, and schools of tropical fish. Neptune's Finger is also a reliable spot for larger pelagics: manta rays, schooling devil rays, yellowtails, and amberjacks pass through regularly, and Mola Mola (ocean sunfish) have been recorded here. White tip reef sharks are also sighted at the site. Schools of sardines form bait balls in the November–January period, and the site can be productive from May through August as well, with the marine park open year-round.

The site is rated for advanced open water divers, and a deep diving specialty is recommended given that meaningful sections of the dive—particularly the sandfalls—are reached well below 100 feet (30 metres). Boat traffic is noted as a hazard.
