A PADI five-star centre on Akumal bay, running the guided turtle snorkel, reef and night dives, cenote dives inland, the full course ladder to instructor, and a catamaran for people who would rather stay on top of the water.
They also sell the archaeological day trips — Cobá, Tulum, Chichén Itzá — which from Akumal are all comfortably close.
