One of the most important sites in Tulum is its Mayan ruins, located on a cliff facing the Caribbean Sea; with warm starry nights and clear turquoise waters lies the only archaeological site that sits on the seashore. It is the most photogenic site in the region and perhaps the whole country.
Under the cliff is Paradise beach, considered one of the best beaches in the Riviera Maya, from which excursions are organized to the famous Mesoamerican Reef Barrier. The Sian Ka'an Biosphere Reserve measures half a million hectares and covers all possible scenarios: beaches, coral reefs, rainforest, dunes and natural wells.
