Panther Den Wilderness, Protected wilderness area in Union County, Illinois.
Panther Den Wilderness is a protected natural area in Union County featuring dense forests, sandstone rock formations, and deep ravines. The terrain includes steep slopes and rocky obstacles that make hiking varied and demanding.
Congress designated this wilderness area in 1990 as part of a broader effort to protect natural landscapes throughout Illinois. This recognition followed decades of conservation work to keep the land from being developed.
The name "Panther Den" refers to the big cats that once roamed these ridges and sheltered in the rock caves. Walking through the ravines, visitors can sense how the natural shelter shaped how both animals and people used this space.
Trails are minimally marked, so visitors should bring maps and a compass along with enough drinking water. There are no modern facilities on site, so self-sufficiency in navigation and planning is necessary.
The sandstone caves and rock crevices here create natural passages and hideaways that hikers can discover while exploring carefully. These hidden spaces become small surprises that add to the walking experience.
