I must start by saying that the experience is a must for any visitor. I came down to the island to visit family during the holiday break [honestly, to escape the first half of the New England winter] and bought this package. I was expecting it to be the same old boring bring your tube and float down the wasted river. To my surprise it was the complete opposite. The staff really knows that exclusivity is their best asset. You pay for an amazing experience within a private property and a small group. If your group is not a family or friends group, you will end up with a new family. The intimacy of the trip and the dynamics of the of it all allow for the creation and strengthening of bonds. Betzy, Emmanuel, Humberto, and Mimi ARE amazing and knowledgeable guides that worry about every little detail but most importantly the safety of you and your group. Being an expat boricua and a biology aficionado, I learned a lot of things from our culture and nature including: distinguishing native bird calls, adjacent cave systems, medicinal plants, and bat behavior behavior. Once you plunge through the cave into the river their ARE A LOT of bonding exercises that you I could mention but rather have you experience. They are fun and learning experiences that allow you to get to know and trust better your family, friends, or new acquaintances. In the end, when you are all soaked, tired and muddy, you can relax by taking a very relaxing and cleansing shower in their so called nature showers. This are very primitive showers where you stand on sturdy wooden palettes at the edge of a 300+ ft cliff with nothing but mother nature surrounding you [AMAZING]. Don't let the previous review about false information deter your decision to go on this trip, it is much better than the tubing experience and this one really is bilingual. Explora is a very professional and solid company, maybe the person forgot to specify that he/she wanted to do the caving adventure, which is a 2.5 hr water cave exploration in the Camuy munipality. That is our next trip as well as the new Level 3 adventure in the making. We are really looking forward to doing future business with Explora and joining them in their new trips. Very satisfied and recommend it completely.
