Boca Paila Peninsula, Peninsula in Quintana Roo, Mexico

Boca Paila Peninsula is a narrow strip of land about 50 kilometres long in Tulum municipality, Quintana Roo, separating Boca Paila Lagoon from the Caribbean Sea. It is the only land connection between the fishing village of Punta Allen and the town of Tulum, linked by a dirt road, and it overlooks the Great Mayan Reef.

The peninsula lies within the Sian Ka'an Biosphere Reserve, a UNESCO site, and forms the only land link between the fishing village of Punta Allen and Tulum, joined by a dirt road. Part of it is protected as the private Boca Paila Preserve, where 1% of the land holds 8 luxury residential estates.

This location is best reached by water or in vehicles suited to unpaved terrain. Conditions can vary greatly depending on the season, especially during the rainy months.

The bridge over the lagoon outlet to the Caribbean is a known spot for sport fishers and fly-fishers. Within the Sian Ka'an Biosphere Reserve, 103 mammal species and 336 bird species have been recorded, and about 1% of the Boca Paila Preserve section is privately owned, holding 8 luxury residential estates.
