We did a tour through the park and saw many sloths, monkeys, birds, & other wildlife. Note that you have to have a guide to enter the park and it is best to go in the morning so the animals are more active. The hotel provides round trip transportation and a tour or there are many other companies that offer tours as well.
The hotel will drop you off where the beach pathway is in a golf cart or you can walk 1/4 mile outside the hotel. The trail to get to the beach is quite rocky and uneven. While this beach is beautiful, it does lack some of the amenities of Manuel Antonio beach. If you're looking to rent a couple kayaks or beach chairs and are ready for a little adventure, this is a well worth it stop.
