To see a Capuchin monkey in Manuel Antonio, is really not hard. They have become so accustomed to people that they are even not scared of flash thunderstorms, but always look if they can not catch anything to eat. If they have success and the donor is caught he must leave the park. It has to be like that.
After we were approached several times on the way to the park if we want to participate in a guided tour, we are glad not to have any guide beside us. For sure they know where the animals are (because of hiding can hardly be spoken).The guides have binoculars and communicate by radio with other guides. If you behave quiet and look closely at the trees, you can discover the capuchin monkeys, and (rarely) sloths but just as well.
Moreover, it is much calmer, if you are not running with a billion other people in the park.
That‘s perhaps why we find some howler monkeys high up in the branches and when we have a look in the brake, we can see a sort of a crake and even two agoutis. The place of an iguana, we saw at the beach, showed us another vacationer.
While wet weather, it isn‘t exiting at all, to climb up to the lookout point El Mirador. Of here you can see the bay and the sea very well. But by humidity, the way is marshy and slippery. So it‘s much nicer to go over the Sendere Punta Catetral, to circle the peninsula (with view over the upstreamed islands) and afterwards to walk along the Sendero El Perezoso, the trail of sloths, straight to the higher exit.
