Conditions & Currents

San Rafaelito offers diverse current conditions, making it suitable for varying experience levels. The protected side of the rock formation experiences calm conditions, ideal for novice divers seeking a relaxed underwater experience. In contrast, the more exposed sections may have mild currents, which contribute to a richer marine activity by bringing in nutrients and drawing pelagic species. Visibility typically remains clear, though it can vary with currents and plankton blooms. Divers should be mindful of sea lion activity, particularly during mating season, when territorial bulls may display more assertive behavior. Entry and exit are typically boat-based, ensuring easy access to the dive site.

Dive profile & how the dive runs

Your dive at San Rafaelito begins with a boat entry directly to the site, allowing immediate immersion into the clear waters around the rocky islet. The dive typically involves circumnavigating the formation, starting on the more protected side for easier entry and gradual depth progression. You will explore the volcanic rock walls, observing colorful gorgonians and sponges. Depths are generally moderate, making it comfortable for extended bottom times. Pay close attention to the playful sea lions that frequent the area, often interacting with divers in the shallower sections. As you complete the circuit, the dive ascends gradually, allowing ample time for a safety stop amidst schooling fish before returning to the surface for boat pickup.

Underwater photography

San Rafaelito offers fantastic opportunities for both wide-angle and macro photography, especially with the frequent sea lion interactions. For capturing the playful sea lions and the scenic volcanic rock formations, a wide-angle lens is highly recommended. These curious creatures often approach divers, allowing for engaging close-up shots without needing to pursue them. When photographing sea lions, maintain a respectful distance and avoid direct flash, relying on natural light or continuous video lights. For macro enthusiasts, the reef's crevices and substrate hide moray eels, octopuses, and diverse small fish, requiring a macro lens to capture their intricate details. Given the site's warm, clear water and moderate depths, buoyancy control is crucial to avoid disturbing marine life or kicking up sediment, ensuring clear shots.

Getting there & logistics

Access to San Rafaelito is primarily from La Paz, Baja California Sur, Mexico. Divers typically fly into La Paz International Airport (LAP) or into Los Cabos International Airport (SJD) and then transfer to La Paz. Most dive operators in La Paz offer day trips to San Rafaelito, which often includes two dives, equipment, snacks, and drinks. Private boat charters are also available, providing more flexibility for small groups. Trips are generally a half-day or full-day excursion, saving time and fuel compared to longer trips to more distant sites like Los Islotes. Marine park permits are usually arranged by the dive operator and are essential for diving in this protected area.

Safety & environment

While San Rafaelito is considered beginner-friendly, divers should always carry appropriate dive insurance that covers medical emergencies and evacuation. The nearest recompression chamber is located in La Paz, making evacuation relatively straightforward compared to more remote sites. Site-specific hazards are minimal, but divers should be aware of potential strong currents in more exposed areas and always follow their dive guide's instructions. When interacting with sea lions, maintain a respectful distance and avoid touching them, especially during mating season when bull sea lions can be territorial. Always ensure your dive operator holds the necessary marine park permits and that the boat captain is properly licensed for safe and responsible diving practices.
