The hang

Akumal Bay is the turtle beach of the Riviera Maya. The beach is free; the main turtle field in the bay is guided only, with a licensed cooperative, at most six people per guide, about 45 minutes in the water, life vest on, no touching and no chasing. In 2026 the licensed circuit runs about $25 to $40 a person, roughly 8am to 5pm, and there are no guided tours on Mondays, a rest day for the reef. A colectivo from Playa del Carmen costs 40 to 50 pesos and drops you at the pedestrian bridge; parking is about 100 pesos a day. If someone on the highway sells you an official entrance ticket, keep walking.
