Up the hill and about 200m east of the beach, La Selva is a small but well-maintained wildlife refuge, with monkeys, iguanas, alligators, coatimundis and other critters. You can use your ticket twice: come in the morning before the heat of the day, then return around sunset when the nocturnal creatures wake up. This is a private venture, so the price of admission pays to protect and rehabilitate these animals. Warning: wear open-toed shoes at your own risk (fire ants).
