T, it was located right up in the hills above San Juan del Sur and called Da Flyin Frog Canopy tour. I thought the price was more than reasonable. It was safe as can be, and I am kind of a chicken for things like that. That, along with the 3 hour sunset cruise for $20, with all the rum (Flor de Cana, yum) and local Tona cervezas one would want, with only a handful of people. I heard they have another good zip line right outside of Managua. Loved the country so much, I have to go back!
I would love to do a zip line near Arenal, very beautiful there as well.
