The reserve is the habitat of herons, innumerable land turtles, screeching peacocks, shy deer, elusive green monkeys, brilliantly colored parrots (in a large walk-in aviary), a snake, and a caiman. The animals run or fly freely, except for the snake and caiman, so step carefully and keep your hands to yourself. Late afternoon is your best chance to catch a glimpse of a green monkey. COST: $11.50.
