Walking 5-10 minutes south of the main road in Manzanillo will bring you to a small hanging bridge that serves as the entrance to Gandoca-Manzanillo National Wildlife Refuge. There are two main trails from this entrance: one that's half beach and half jungle and one that goes deeper into the greenery of the park. The reserve property stretches across not just Manzanillo, but also across Punta Uva and Playa Chiquita, though most of the trails are in the Manzanillo area. Go early in the morning for the best chance to spot shaggy sloths and black howler monkeys. Should you decide to have a picnic on one of the beaches along the trail, beware the charms of the white-faced capuchin monkey. Their innocent-looking faces may sway you into tossing a snack their way, but once fed, half a dozen will likely swarm your lunch grounds, and they won't be polite. As a general rule, don’t share your lunch with the wildlife.
