We took a rubber raft with a guide. We are a family of five,with the youngest kid is almost four. The rafting was perfect for us. The guide was professional and the equipmentt very good. They gave us a dry-bag for our valubles and even a ride back to the starting point where we parked the car. Excellent experience.

Maria was very responsive to my questions before arriving. They have high quality equipment and know what they are doing, which is very important. They made sure all the safety equipment (helmets and life vests fit properly before going out on the water). I recommend taking a light sweater/ rain jacket and putting it in the water tight container that goes with you in the raft since the weather changes so radically.
In addition, we would have enjoyed the trip more if our guide had spoken better English. His English was really minimal and that was a pity as we would have liked to have known more about the park and surrounding area.
I also highly recommend renting mountain bikes at the end of the rafting experience and riding back through the National Park to the starting point! Beautiful area!
