The trails of Lewis and Clark Caverns State Park allow the visitor to enjoy and experience many aspects of the park above and beyond the caverns themselves. There is over 3000 acres of terrain in this park and almost 1600 vertical feet. The trail system covers about 10 miles and over 1000 feet in elevation change. The two main trails are rather strenuous with considerable elevation gain or loss, but there are others that provide a more relaxing walk through the park.

For those looking for a less challenging hike, the short Nature Loop Trail located at the upper picnic area is a pleasant quarter mile walk with signs to identify some of the flora. This short trail offers some of the best wildflower viewing in the park. From the campground the Fishing Access Trail can take you a leisurely 1.3 miles down to the riverside for fishing, swimming or just a reflective moment by the historic Jefferson River. The trail picks up less than 100 feet.
