Like most desert wildernesses in Nevada, the Calico Mountain Wilderness has no designated trails. This lack of established trails within this Wilderness heightens the experience and adventure, requiring hikers and explorers to develop backcountry navigation skills and confidence in traversing rugged country. For those up to the challenge, sweeping vistas from the summits of Donnelly and South Donnelly Peaks reward hikers. The Wilderness also offers outstanding opportunities for rock hounding and geological sightseeing within ever-changing rock formations.
