After visiting 5 national parks I can confirm this one is the one with more wild life, its just 3km walk path but you can see a lot of monkeys, lizards, birds, frogs, crabs, insects, paca, bats and more! Hotels and tour guide will force to have a paid guide but you can do a walk in without because all people inside the park will show you where any animal was. Also the park has exit to the beach and you can walk there too, last entry is at 3pm!
