Macal River Jungle Camp - Set high on the river's lush banks, close to the ancient Mayan ruins of Tipu and Xunantunich, is the Macal River Jungle Camp. Scattered throughout tropical rainforest are ten casitas, or small bungalows, each on a raised platform with airy peak-roofs, full screens and containing two comfortable beds. Each casita has a private sheltered porch for quiet relaxation and peaceful views into the undisturbed jungle habitat.
