Acapulco’s cliff divers may be more famous, thanks to the resort city’s longer history of tourism, but Mazatlán’s divers are equally well-conditioned and daring, flinging themselves with grace and courage from the top of a cliff and into the churning waters of the Pacific below. They do this after climbing the cliff face, so the feats of athleticism are on full display. They make their living from tips, so be generous with yours.
