About Isla Contoy


Isla Contoy is a small uninhabited island that belongs to the municipality of Isla Mujeres in the state of Quintana Roo, Mexico.

Protected by the Mexican government since 1961, it was declared a National Park in 1998 and it is also known as “The island of birds”. South of the island  the “Ixlache” reef is located right where the 2nd biggest reef barrier in the world starts.

Isla Contoy is run by the non-government organization Amigos de Isla Contoy A.C. and supervised by the SEMARNAT (Secretary of environment and natural resources).

The Word “Contoy” can come from 2 different sources, Kom which means low and To’oy which means shelter describing the low depth waters around the island or the vocable Ponto which means Pelican.


Based on findings made on the island like ceramic ítems it has been calculated that the island would have been occupied since 300-200 bc, even before consolidation of the mayan culture, in the period known as “preclassic superior”. The island was a part of the ancient pre-hispanic maritime route that linked the Laguna de Terminos with all the Caribbean islands that covered all the Yucatan peninsula’s coast.

During the colony its surrounding waters were witness of naval battles between galleons and pirate ships as well as shipwrecks. The first oficial news out of the island comes from John L. Stephens back in 1892 who specially mentioned the presence of a large number and different kind of birds, other sources mentioned that, during the 50´s, the island was temporary inhabited by turtle camps, this activity remained for a while and it represented an important activity for the locals up to 20 years ago.

During Porfirio Diaz presidency, in the late 1800’s and early 1900´s, the lighthouse for the island was constructed. Back then the Island was already called “Island of birds” and it began to be recognized as a sanctuary.
