Dive Site: Cenote Car Wash (Aktun Ha)

About Cenote Car Wash (Aktun Ha)

Cenote Car Wash, also known as Aktun Ha, is a renowned dive site located just outside Tulum in the Riviera Maya. This cenote gets its name from a past era when local taxi drivers would conveniently wash their vehicles in its accessible waters. Today, it offers an easy entry point for divers, featuring a large, open-air pond-like area surrounded by lush jungle vegetation. The crystal-clear water allows visibility to the bottom from the surface, creating an inviting environment for all divers. The dive begins in the open water section, which is about 5-6 meters deep and teems with freshwater fish and aquatic vegetation like water lilies. A prominent fallen tree towards the cavern entry point provides a dramatic visual, with sunlight filtering through its roots, creating an impressive light show when viewed from inside the cavern. As divers progress into the cavern, they encounter striking dripstone formations that adorn the underwater landscape. Buoyancy control is essential due to varying depths and features within the cavern system. During the summer, after the initial rains, the shallower waters develop a milky cloud due to organic material. Diving beneath this layer reveals an astonishing spectacle where the water takes on different hues, from yellow-green to almost red, depending on the sunlight's intensity. This natural phenomenon makes for a unique and memorable dive. Cenote Car Wash is also a popular training ground for cave divers, offering convenient facilities and serving as an access point to "The Room of Tears" for those with advanced cave diving certifications.

Conditions & Currents

Cenote Car Wash, like most cenotes, is characterized by an absence of currents, waves, and wind, as the dive takes place in an underground or semi-enclosed environment. This provides a consistently calm and stable underwater experience, making it ideal for divers who prefer placid conditions. Visibility typically remains outstanding, often exceeding 25 meters, due to the crystal-clear freshwater. While surface runoff from heavy rains might briefly affect clarity at the immediate entry point, conditions deeper down are consistently pristine. Water temperature remains stable year-round, between 24-26°C (75-79°F), removing concerns about thermoclines at recreational depths. Divers can expect an easy entry and exit, focusing on buoyancy control to protect the delicate formations and plant life within the cenote.

Dive profile & how the dive runs

Your dive at Cenote Car Wash (Aktun Ha) typically begins with an easy entry into the large, open-air basin. Descend into the clear freshwater, immediately noticing the abundant aquatic vegetation and intricate tree roots that line the edges. The dive often follows a circular or out-and-back route, guiding you from the brightly lit open section into the more ambient light of the cavern zones. You'll progress slowly, exploring the fascinating rock formations and keeping an eye out for the resident freshwater crocodile and various fish species. Depths generally remain shallow, around 10-14 meters, allowing for extended bottom times. The turnaround point is often dictated by air consumption or reaching the more enclosed cavern areas. Ascent is gradual, allowing you to enjoy the transition back to the open water, with your safety stop easily conducted in the clear, shallow areas near the surface.

Underwater photography

Cenote Car Wash offers excellent opportunities for both wide-angle and macro photography, thanks to its varied environment. For capturing the expansive open-water sections, the striking root systems, and the overall ambiance, a wide-angle lens is ideal. Be prepared for strong natural light in the open areas and transition to more subdued lighting within the caverns. Strobes can be beneficial for illuminating details in the darker sections and bringing out the colors of aquatic plants and fish. Practice excellent buoyancy control to avoid disturbing the fine silt bottom and delicate root structures, ensuring clear shots and preserving the site. If you're hoping to photograph the rare freshwater crocodile, a zoom lens might be useful from a respectful distance.

Safety & environment

Diving in Cenote Car Wash, while generally considered safe and beginner-friendly, requires adherence to standard cenote diving protocols. Always dive with a certified guide experienced in cavern diving due to the overhead environment.
