We did the half day Rio Balsa Class II & III rapids with Desafio. It was first-rate from start to finish. The driver picked us up promptly, there was plenty of help at the river, & the meal afterward was great. As an example of their attention to detail, during the mid-trip fruit break, one of the rafts was turned upside down for a table & the fruit was sliced right there by the guides & arranged quite artfully. Our guide, Diego, made the trip safe & fun for us, especially our 10-year old who was pretty scared at first; he had her laughing & paddling away by the end. This is a great trip for those new to white water rafting
