A lot of cavers have a GPS unit, and many of them are also Geocachers, so we will have a Geocaching course for anyone that is interested. The course features many different kinds of caches, and will be a challenge for novices as well as more advanced geocachers.

It's a lot like hunting for Easter eggs, but you can do it any time. Adults like the challenge and the exercise, and kids love it too!
