About Neptune's Finger
Neptune's Finger is a renowned dive site located in Cabo San Lucas, Mexico, at the southern tip of the Baja California Peninsula. Its name comes from a distinctive rocky pinnacle that extends approximately 8 meters (26 ft) above the water's surface. This iconic formation marks a unique underwater landscape that has served as a navigational landmark for decades. The site is a premier destination for scuba diving due to its blend of geological wonders and diverse marine ecosystems, embodying the rich marine life of the Sea of Cortez. Beneath the waves, the site features a complex topography, including two distinct coral reefs and multiple shallow pinnacles adorned with various coral types. A prominent vertical wall drops dramatically to depths exceeding 152 meters (500 ft), making it suitable for technical diving and offering a dramatic backdrop for exploration. Divers will also encounter the largest sandfall within the Cabo San Lucas Marine Park, a mesmerizing natural phenomenon where sand cascades down the seabed. The pinnacles extend all the way to the surface, providing excellent opportunities for extended safety stops. Marine life at Neptune's Finger is abundant and varied. The shallow areas are particularly notable for macro subjects, including numerous nudibranchs. Along the wall, large schools of snapper are common, and a butterflyfish cleaning station provides interesting viewing. Visiting turtles are frequently sighted, and during the mobula and cow nose ray seasons, large schools of these rays are known to pass overhead. Other pelagic species such as tuna, bonitos, barracudas, and sardines are regularly encountered, alongside eagle rays, mantas, and guitarfish. Sharks, whales, and dolphins are also common sightings in the general area. The site is accessible to Open Water or CMAS* certified divers. While diving is possible year-round, calmer seas and clearer visibility are more prevalent during specific months. Divers can expect to explore unique geological formations and a rich diversity of marine life across various depth bands, from shallow reef tops to deep wall sections, typically making it a multi-faceted dive experience.

Conditions & Currents
Currents are usually mild, which makes this a relaxed dive suitable for most certified divers. Dive profiles here run between roughly 4 and 152 metres, so plan your gas and no-decompression limits around the deeper part of the site. It is usually briefed as a dive for beginner divers. It can be dived from a liveaboard or a day boat, depending on where you start the trip. Tide, wind and season all shift the picture from day to day, so the crew's briefing on the boat always overrides any general description.
Why dive Neptune's Finger from a liveaboard?
Neptune's Finger is one of Mexico's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
