Geo Caching

Some call it a sport, some say it's a treasure hunt. We think of it as a real-world adventure!

Our counties three offical Geo-Trails will challenge and engage you in your pursuit to locate over 50 caches.  The beauty of our area coupled with our history, arts, and culture will surprise and enlighten you as search. Geo-Trail caches can be found at our national, state, county and town parks, as well as at museums, wineries, historical sites and places of natural beauty.  Cachers have come from all ove the USA to take on our trails, and we are proud to have hosted the GeoWoodstock 2015 event!
