This was one of the cooler things we did in Costa Rica. All in all it's a tarzan swing, 10 ziplines (some really long and beautiful), rappeling down the forest, and climbing the inside of an old ficus tree. You're able to opt out of things if they're too intense, but I recommend doing it all! The guides were all super friendly and knowledgeable and we felt incredibly safe and secure at all times. Highly recommended!
