Conditions & Currents

Currents at Los Islotes are generally limited to medium strength, making it accessible for most diver levels. However, conditions can vary, so divers should be prepared for gentle to moderate water movement. Visibility consistently remains excellent, typically ranging from 20 to 30 meters, often reaching up to 35 meters in peak conditions. Water temperatures fluctuate seasonally, from a high of 30°C in September to a low of 16°C in February, potentially necessitating thicker wetsuits during cooler months. While thermoclines can occur, surface conditions are often calm due to the sheltered nature of the Sea of Cortez, though winds can cause chop. Divers should always conduct a boat entry and exit, maintaining situational awareness of boat traffic around the islands.

Dive profile & how the dive runs

Diving at Los Islotes typically involves a boat entry directly into the water near the rocky islets. You can opt for two main dive routes: a southern, shallower exploration or a northern, deeper route. The southern dive often includes an interesting cave system. The northern dive offers potential encounters with pelagic species in deeper waters. Most divers prefer to stay shallow to interact with the sea lions, often circling the islands at depths of 8 to 15 meters, moving through archways and swim-throughs. The sea lions themselves will approach and play, often initiating interaction. A typical dive time is limited to 45 minutes to ensure respectful interaction and to avoid over-stressing the animals. Safety stops are generally performed in the shallower reef areas, often still surrounded by playful sea lions.

Underwater photography

Los Islotes presents exceptional opportunities for wide-angle photography, capturing the playful California sea lions in their natural habitat, often against the dramatic backdrop of the rocky islands or schooling fish. A wide-angle lens (e.g., 8-15mm fisheye or 16-35mm rectilinear) is ideal for these interactions. Consider using strobes to bring out the vibrant colors of the angelfish, corals, and other reef life, especially in deeper sections or within the caves. For sea lion interactions, be prepared for fast-moving subjects; high shutter speeds and continuous autofocus will be beneficial. Respect the animals' space, letting their natural curiosity guide interactions, rather than chasing them. Buoyancy control is paramount, particularly in shallower areas, to protect the delicate golden cup corals and maintain clear visibility.

Safety & environment

Los Islotes is generally considered safe for all levels of divers, but interactions with wild sea lions require caution. While juvenile sea lions are playful, adult bulls can be territorial, especially during breeding season. Divers should maintain a respectful distance from the rocks where bulls reside. The nearest recompression chamber is located in La Paz. Comprehensive dive insurance is highly recommended, covering emergency medical care and evacuation. In case of an emergency, evacuation would be by boat back to La Paz. Always follow your dive guide's instructions regarding conduct and interaction with marine life, ensuring both diver and animal safety. Be mindful of currents, which can be moderate, and always plan your gas supply accordingly.
