Discover your connection to Upper Michigan’s Copper Country through heritage centers, museums, and outstanding recreational areas in this geo-trail developed by the Copper Country Trail National Byway. The Copper Country Trail National Byway is a 47-mile stretch of US-41 from Houghton to Copper Harbor in the Keweenaw Peninsula of Michigan that follows the underground copper lode that is basis of our exciting and turbulent history.
Geocaches have been hidden at 17 participating sites throughout the Keweenaw Peninsula. All of the sites on this geo-trail represent the rich cultural and natural mosaic that the Copper Country is. The first 300 participants to locate at least 13 geocaches will receive a custom Copper Country Geo-Trail lapel pin.
To receive a lapel pin, participants must download the Copper Country Geo-Trail Passport and follow the directions.
