With 260 miles of hiking, biking and horseback riding trails, Hoosier National Forest is a favorite among adventure seekers. Even rock climbers can find suitable rocks and cliffs within the park.
Brush up on your map and compass skills in the Orienteering Area, an established course with 25 markers; then swing by Hemlock Cliffs to explore waterfalls and rock shelters within a box canyon.
There are also two scenic highways and several historic sites in this 202,000-acre forest. Note that trail tags are required for mountain bikers and horseback riders and parts of Hemlock Cliffs are off limits to climbers.
