Zip lines are incredible fun for the whole family. My wife and I tried it in Whistler last May. It was a top notch operation promoted team building for the more nervous folk and they also taught you about the local ecology of the Northern Pacific rain forest and the importance of running a 'green' operation in the mountains.

If the local ones there are half as much fun, it will be a great use of your leisure dollars.

With great power comes Awesome irresponsibility.
