Bonanza Mine is a 7.8 mile lightly trafficked out and back trail located near Copper Center, AK that offers scenic views and is rated as difficult. The trail is primarily used for hiking, trail running, and backpacking and is accessible from June until September.
This is in Copper River region, but over 100 miles southeast of Copper Center within the Wrangell St.Elias National Park. From the footbridge in Mc Carthy, hike on the road a half mile east, head north. Around a turn to the airport, less than a mile, take Old Wagon trail on left. It parallels the road.
Total about 4.5 miles to the mines in Kennicott.
Go past the mill buildings along the wagon trail on east side of glaciers. Cross two strams, with footbridges, to hike to abandoned Erie mines, another few miles.
Good mountain biking for first 6 miles, gentle slope up. Then, becomes too narrow with glacial till and sharp inclines off trail. Access trails to climb on glacier. At Jumbo Creek can get under glacier, but it's hazardous on warm afternoons especially.
