surprised. There is one of the best or longest zip lines in the world there I think - done a couple of different zip lines if that is your thing. We also did a tubing down the irrigation canal through tunnels - can't remember what that is called. I think we took a tour where we walked into a large lava tunnel as part of one of the zip line tours.

Helicopter ride is $$$$$, but very unique experience. just check out the price before you announce it to your family. None of these suggested activities are inexpensive.
