I’ll list Manuel Antonio as one of my favorite Costa Rica beaches, because I spent the most time here. When you get here you will see why. Imagine world class horse shoe beaches nestled in between monkey and sloth filled jungles, and an ocean with year-round warm waters, and you’ll begin to see the appeal. The are the popular beaches, such as the main one next to the national park, and then there are hidden, not-so-well known ones such as Playa Biezans, that only a local can show you.
