The zip line adventure near the top of Mombacho volcano was a lot of fun. One of the best parts of it (no kidding!) were the staff. Funny, engaging, knowledgeable, and very concerned with safe operation of the zip line at all times. I am kind of afraid of heights (!) but promised by son I'd get through it with him. I was surprised at how safe I felt, and the slightly panicky adrenaline rush was actually pretty fun. A great way to challenge yourself, and lovely views. Flew right by a toucan at one point. Pretty cool!
