Direct answer
Yes — Tulum is the only Mayan site on the Caribbean coast, with cliffs over a turquoise beach. Go right when it opens (8am) — by 10am tour buses arrive and it's mobbed. Allow 1.5–2 hours. Combine with Playa Paraíso beach below. Entry ~95 pesos plus 60 pesos shuttle (or walk).
Tulum's ruins are the only Mayan archaeological site directly on the Caribbean coast — pyramids and temples perched on a cliff above turquoise water. They're smaller than Chichén Itzá but uniquely photogenic. Get there for the 8am opening; by 10am the tour-bus crowds make it miserable. Allow 1.5–2 hours plus 30 min to walk down to Playa Paraíso below.
