This is the most popular route to Harney Peak – be prepared to encounter many people, especially in the summer.
Hikers begin on a roadbed that leads to a fire tower built by the Civilian Conservation Corps, now on the Register of Historic Places.
The trail is steep, but the rewars include stunning views of four states.
