Standing on the edge of the Belizean jungle, it's hard to imagine the wonders hiding inside. Or maybe it's all too easy to imagine them—what lurks within? Whether you're excited or a tiny bit fearful, it's best to go “back of bush” with a knowledgeable guide who can identify the flora and fauna of this unique habitat. Colu's guide, born and raised in the area, brought local wisdom to bear on their trek as he pointed out medicinal plants and helped her learn to use her senses to “read” the river and its surroundings. Visitors to the jungle—which counts five distinct ecosystems—should be on the lookout for howler monkeys (you may have been tipped off by the river’s name!), as well as colorful toucans, manatees, tapir, and silent, stealthy creatures, such as ocelots and jaguars.
