I am just going to warn you that when you get off the main road it is dirt and bumpy (we just laughed the whole time). The park is worth the drive. We saw less than ten people the whole time we were there. The hike is pleasant. The bridges are fun to walk over and the swim at the base of the waterfall was refreshing (bring towels and a change of clothes). We made the hike so we hit the waterfall towards the end. Would recommend getting there early - we had rain (didn't bother us though). Might have a better chance seeing more wildlife.

We did the self guided walk by day with our teenage children who loved the bridges and platforms in the trees, we saw lots of wildlife and were really pleased to see a 'poison dart frog'. We only met one other group of people there near the end, so had the place to ourselves. You need decent footwear as the paths and bridges are tricky in places, the walk took us about 2 hours in all, as we didn't go into the waterfall pools. We waited around and had the guided nightwalk also, which was a great experience. We saw loads of things you never see by day and we were so lucky as we saw 2 types of the 'red eyed tree frog' one of them jumped onto our daughters coat!. Great value and well worth the drive from Manuel Antonio.

Don't forget to get a guide, if not you won't see animals! You can see snakes and frogs! Take a bath in the waterfalls, its a great experience!

Fantastic Park! Affordable, self-guided tour that included canopy bridges, waterfall, swimming, and beautiful wildlife and scenery. We didn't have a guide and were still able to spot many butterflies, frogs, snakes, lizards, and other insects. The bridges were awesome! The waterfall was beautiful and swimming beneath it was refreshing in the Costa Rican humidity. We basically had the park to ourselves and were able to take our time exploring along the trail. Great experience and highly recommended!
