Mario's kids are visiting us from Canada so we went to Manuel Antonio to see the wildlife and spend some time on the beach. Manuel Antonio is a national park. It is well worth the trip and the price of a guide. It is not a zoo so each time you go you see different animals. The guides carry telescopes and set them up so you can see the animals clearly. They are very knowledgeable. We saw many different species of bats on this trip.
Not being one of my favorite animals, there are no pictures :).
You don't need a telescope to see the monkeys. They run along the beach stealing food and fun things from the tourists. The parks discourages contact with them, but they don't seem to care.
You need to secure everything if you hang out on the beach. We saw them steal a cracker from a toddlers hand!Still they are really cool to watch. I never get tired of seeing them. The kid's got a kick out of them too.
You usually can catch sight of a sloth or two as well. This baby was hanging out in a tree very close to the trail. I missed the shot where he looked right at us, but the smiling face is unforgettable.
