Breathe beneath Cozumel’s blue and meet the reef on a one‑tank Discover Scuba at Chankanaab Park. Ideal for first‑time and certified divers alike, this guided intro dives through coral gardens, an ancient cave mouth and underwater sculptures.
The boat slips into glassy water and the island exhales salt. In Chankanaab National Park, a short shore entry dissolves the boundary between land and sea: bright mangroves give way to a corridor of coral where parrotfish nibble and a sculpted figure stands sentinel beneath the surface. On a Discover Scuba one‑tank dive here, your world narrows to the hiss of your regulator, the rush of breath, and the slow choreography of reef life.

Be at MJ’s Dive Shop at Chankanaab Park 15 minutes before your scheduled time to complete waivers and fit masks and BCDs without rushing.
Apply a mineral or reef‑safe sunscreen before arrival—regular chemical sunscreens harm corals and are discouraged in the park.
Drink water before your dive and skip alcohol for 24 hours prior to reduce dehydration and risk of decompression issues.
A lightweight waterproof pouch keeps your phone, money and park wristband dry while you’re gearing up or relaxing after the dive.
Chankanaab was historically a Maya coastal site; the park preserves both archaeological references and modern marine conservation initiatives.
The park enforces no‑touch rules, encourages reef‑safe sunscreen, and supports local reef monitoring programs to protect coral and fish populations.
Protects your skin and the coral—apply before arrival to minimize chemical run‑off.
