Inland Blue Hole
The St. Herman’s Blue Hole National Park is among the many popular inland attractions in Belize. It is located just off the Hummingbird Highway in the Cayo District.
Perfect for a refreshing swim, this spot features an underground river that converges into a crystalline pool surrounded by lush greenery. It is a limestone cave formation filled with water that reflects an incredibly blue color – hence the name. This geological formation is part of the massive Belizean cave system that has been largely unexplored.
The park is over 500 acres (2 km) in size, and contains tow cave systems (St. Herman’s and Crystal), various trails, and the cool jungle pool from which the park gets its name. This area is also home to a variety of wildlife, and trees are labeled for identification. Over 200 bird species was discovered here.
The Government of Belize acquired the land for the park in the 1960s and ’70s. It was officially declared a national park on November 23, 1986.
*Note: This inland “blue hole” is not to be confused with the offshore Great Blue Hole at Lighthouse Reef Atoll.

Guanacaste National Park

The history of Guanacaste National Park is both fascinating and unique. Notably, the park derives its name from a massive Guanacaste tree that avoided being logged due to its trunk splitting into three bases, which diminished its value as timber.

Managed by the Belize Audubon Society, the park is primarily operated as a bird sanctuary. In addition, the park showcases two distinct types of forest, which provide habitats for a diverse array of animals. It is home to over 100 bird species, making it a haven for bird enthusiasts and wildlife lovers alike.

Animals, including the white-tailed deer, jaguarundi, kinkajou, nine-banded armadillo and countless others are observed by visitors. Bird species including, the he Lesson’s motmot, black-faced antthrush, smoky-brown woodpecker, black-headed trogon, red-lored amazon and magnolia warbler are just a few of the species seen.
