St. Herman's Blue Hole National Park is a national park located just off the Hummingbird Highway in Cayo District of Belize, near Belmopan, the capital city. It is over 500 acres (2 km²) in area, and contains two cave systems (St. Hermans and Crystal), various natural trails, and the cool jungle pool from which the park gets its name. The park is managed by the Belize Audubon Society.
This inland "blue hole" is not to be confused with the offshore Great Blue Hole, also in Belize.
