Manuel Antonio National Park will fill your expectations of what Costa Rica is in a 100%. White-faced monkeys playing and jumping around. Sloths just chilling out on the trees. Howler monkeys and their powerful noise. And awesome views of the Central Pacific coast just to say some of the dozens of things to experience here.
Remind that an official guide with an spotting scope is primordial in this park to do not miss any hidden lizards, frogs, spiders and sloths. Private tours for families or couples are a good deal to avoid big groups which are normal in this busy park.
Other activities such as catamaran, rafting, canopy, mangrove forest, night tours and others come with an special discount for booking them with an official guide. Bring your swimming staff!
