About Blow Hole

Blow Hole is a prominent dive site situated along The Corridor, an 18-mile stretch of coastline between Cabo San Lucas and San José del Cabo in Mexico. This area is renowned for its vibrant marine encounters, benefiting from the unique conditions created by the Pacific Ocean meeting the Sea of Cortez. The site is a hotspot for observing larger marine species, making it a significant location for divers seeking diverse wildlife in the region. The underwater topography at Blow Hole features rocky reefs, evolving into walls and sand channels that are rich with life. Divers typically explore depths ranging from 8 meters (26 feet) down to 30 meters (98 feet), or potentially 15 meters (49 feet) depending on the specific location. These varied structures provide ample opportunities for exploration, from observing reef inhabitants on the rocky formations to navigating the sandy expanses. The site is celebrated for its potential encounters with a variety of marine life, including boxfish, pufferfish, and trumpetfish. You might also spot pork fish, gorgonian fans, and white tip sharks patrolling the area. While seasonal, the region is known for large pelagic encounters, with whales and dolphins being common sightings, alongside turtles and sharks. This makes Blow Hole an exciting dive for those interested in diverse aquatic ecosystems and the chance to witness larger marine animals. Access to Blow Hole is exclusively by boat, typically a 20-minute journey from the marina in Cabo San Lucas. The dive is considered suitable for various certification levels, including Open Water and Advanced Open Water divers, allowing a broad range of experience to explore its depths. Divers can anticipate a single dive or include it as part of a multi-dive excursion in The Corridor.

Conditions & Currents

Information on specific current strength and direction at Blow Hole is not explicitly detailed in the provided sources. However, the broader Cabo San Lucas Marine Park area, which is nearby, is generally characterized by calm seas and minimal current, though this specific site is outside the marine park. The dive is accessed exclusively by boat. Divers should be prepared for boat entry and exit. Visibility, thermoclines, and specific surge conditions are not mentioned, but the region typically offers good underwater clarity. Given the reported depths, an Open Water Diver certification is a minimum requirement, with Advanced Open Water recommended for deeper exploration. Divers should always consult local dive operators for the most current conditions and planning.

Why dive Blow Hole from a liveaboard?

Blow Hole 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.
