Chiquibul National Park is Belize's largest national park. It is 1,073 km² (414 square miles). The park is located in the Cayo District of Belize and borders Guatemala. The park is home to a diverse range of plant and animal life, including jaguars, scarlet macaws, keel-billed motmots, kinkajous, and many other species.
The national park is also home to Caracol, a Mayan city that was once one of the largest cities in the Maya world. Caracol was abandoned in the 10th century, but its ruins remain an important archaeological site.
It has Belize's largest breeding population of scarlet macaws. New insect and crustacean species have been discovered in the park. The biological diversity of the park has not yet been fully explored. In 1993, a botanist from Missouri Botanical Garden collected more than 130 plant species previously unreported in Belize. Three of these species had never before been reported in Central America.
