This waterfall is such a rush! The rocks block the water most of the way across the top, so that there is a huge divet where all the water rushes, and you just position yourself there and let it launch you off! It is crazy and soo fun!
We went to Uvita a few years back, just as it was beginning to become more developed, and had an amazing time. We stayed at the Tucan Hotel (it's more like a hostel) and immediately made friends with the owners and their children. Their boys were adventurous little rascals, and showed us this awesome waterfall waterslide a short walk up the road from the hostel (uh, and yes, they demonstrated for us how to do it). There was just a bar/restaurant there at the time (which had amazing food), Cascada Verde, and apparently they have some guest rooms now too. A once in a lifetime experience!
