Cancun's Best BeachesCancun has two distinct beach "zones," one on the northern side, one on the eastern side. Those on the northern side tend to be less intensely aquamarine in color but calmer and shallower, better for families traveling with kids. Beaches on the eastern side have more beautiful water but the currents tend to be unpredictable, so swim with care. On the northern side, Playa Juventud is popular for snorkeling and Playa Tortugas is a favorite of local families. On the eastern side, Playa San Miguelito may be small, but it boasts a special feature: a peek of a nearby Mayan site. Playa Delfines typically lives up to its name, as dolphins are often spotted here.
