Dive Site: La Muela

About La Muela

La Muela, often referred to as 'Molar Tooth', is a distinctive rock formation emerging from Refugio Bay on the northern side of Angel Island within Mexico's Sea of Cortez. This site serves as an excellent introduction to the region's underwater environment, often utilized for initial check-out dives for liveaboard guests. Its shallow depths make it accessible and enjoyable for a wide range of divers. The topography around La Muela consists of a rocky bottom providing diverse habitats. While primarily known for its shallow check-out opportunities, the surrounding areas of Angel Island feature walls covered in gorgonians and hydroids, alongside numerous rock outcroppings, bays, and coves. The site is a microcosm of the rich biodiversity found in this part of the Sea of Cortez. Marine life here includes a variety of macro subjects such as bluespotted jawfish, which inhabit burrows in the rocky substrate, and several species of stingrays. Fine spotted moray eels are also commonly sighted. The broader Angel Island area is frequented by California sea lions, and pelagic species like whale sharks, sperm whales, pilot whales, dolphins, manta, and mobula rays can be encountered seasonally. Diving La Muela typically involves boat access, often from a liveaboard exploring the Midriff Islands. The conditions are generally calm, making it a comfortable dive. It’s an ideal spot to adjust gear and buoyancy while observing the thriving marine community in relatively shallow, protected waters.

Conditions & Currents

Conditions at La Muela are typically serene, making it suitable for check-out dives and less experienced divers. The site is located within Refugio Bay, a protected anchorage at the northern end of Angel Island, which generally shields it from strong ocean currents. While the broader Sea of Cortez can experience varying current strengths, this specific bay usually offers calm waters. Visibility is often excellent, especially during the summer and fall months, enhancing the viewing of macro life and reef inhabitants. Entry is typically from a skiff or tender, allowing divers to easily access the site's shallow rocky bottom without significant current challenges.

Dive profile & how the dive runs

A dive at La Muela typically begins with a skiff transfer from a liveaboard, followed by a straightforward entry into Refugio Bay's calm waters. The dive proceeds along the rocky bottom surrounding the La Muela rock formation, focusing on shallow depths ideal for buoyancy checks and gear adjustments. Divers explore the burrows and crevices for macro life such as bluespotted jawfish and fine spotted moray eels, while observing various stingrays on the substrate. The route is generally relaxed, allowing ample time for observation of the diverse reef ecosystem. The dive concludes with a gradual ascent from the shallow depths, followed by a safety stop. Exit is typically back to the waiting skiff.

Underwater photography

La Muela is well-suited for macro photography, especially with its resident bluespotted jawfish often found peeking from their burrows. A macro lens will capture intricate details of these shy subjects, as well as the various stingrays and moray eels encountered. Wide-angle photography can also be effective if California sea lions are present, capturing their playful interactions against the rocky reef backdrop. Natural light is often sufficient in the shallow, clear waters, but external strobes or video lights will enhance color and detail, particularly in shaded areas or for macro subjects. Practice good buoyancy to avoid disturbing the fragile habitats.

Getting there & logistics

Access to La Muela is typically part of a liveaboard itinerary exploring the Midriff Islands of the Sea of Cortez. Trips commonly run from Saturday to Saturday, including multiple days of diving. Passengers often embark from Puerto Peñasco, Mexico, after transferring from Phoenix Sky Harbor International Airport in Arizona. These liveaboard expeditions provide a comprehensive diving experience, combining La Muela's introductory dives with explorations of other sites along Angel Island, offering opportunities for both reef diving and encounters with pelagic species like whale sharks and sea lions.

Safety & environment

While La Muela is a relatively shallow and calm dive site, general dive safety protocols apply. Divers should ensure their equipment is in good working order, perform buddy checks, and maintain conservative dive profiles. The nearest recompression chamber would be in larger population centers like La Paz or Puerto Peñasco, requiring significant evacuation time in an emergency. Therefore, comprehensive dive insurance covering medical emergencies and evacuation is crucial. Divers should be mindful of their surroundings, particularly when sea lions are present, to observe without disturbing. All liveaboards will have trained dive masters to lead dives and assist divers, ensuring safe conduct throughout the trip.
