Big Bone Lick State Historic Site

The Discovery Trail is a 4.5 mile trail mosaic comprised of all the park’s hiking trails combined into continuous circuit. Collectively, the trails pass through grasslands, woodlands, a woody savanna, the salt-sulfur springs, and the bison viewing area.”

Discovery Trail

The Discovery Trail begins at the Megafauna diorama, just behind the visitor’s center.  The trail meanders along Big Bone Creek past interpretive panels that impart the prehistoric drama that unfolded around the salt/sulfur springs during the last Ice Age.  The trail is open daily from dawn to dusk.


Orienteering is a woods navigation sport wherein participants use map and compass or GPS to navigate an established course.  Big Bone Lick’s orienteering courses were the site of the 2012 U.S. Intercollegiate and Interscholastic Championships as well as the 2015 Kentucky Outdoor Adventure Games.  The park currently offers two permanent, woodland orienteering courses.  A beginners’ course covering 2.7 km and an intermediate course covering 4.5 km, both featuring 10 checkpoints.

Mid to late spring is accented by the arrival of the Ruby-throated Hummingbird and a host of colorful warbler species. In summer, an assortment of hawks pinwheel high overhead during the day and the haunting calls of owls echo through the forest at night. Fall ushers in opportunities to see migrating communal flocks as they flit and dart about, searching for tidbits and morsels to fuel their journey. After the leaves have fallen, the starkness of the barren landscape affords unhindered views of over 50 species of birds that over-winter in the park. Altogether, Big Bone Creek Trail is likely the premiere locale within the park for year-round birding.

Spacious campground features 62 campsites with utility hookups, grills, a swimming pool and playground. Showers, rest rooms, and laundry facilities are available at a central service building.
