A stunning national park on the Pacific coast, Manuel Antonio has it all: nonstop beautiful beaches, lush tropical rainforest, and oh, the wildlife and flowers, everywhere you look. Monkeys abound on these beaches, and they are not timid around people. This is the place (the only place, thankfully), where a monkey pooped on my head. Ah, the memories... The Viewpoint Trail hike is an uphill climb to this lookout (mirador) with outstanding views of the coastline.
