Thunder Basin National Grassland offers expansive mixed-grass prairie landscapes, rich wildlife, and diverse recreational opportunities including hiking, wildlife viewing, and scenic driving in northeast Wyoming.
Thunder Basin National Grassland encompasses over 572,000 acres in northeastern Wyoming, predominantly within Campbell, Converse, and Weston counties. The grassland lies at the transition zone between the Great Plains grasslands and the sagebrush steppe, providing a unique mix of prairie and shrubland ecosystems. This area is notable for its rolling hills, rugged canyons, and wide-open skies. The grassland features diverse habitats that support abundant wildlife such as pronghorn antelope, mule deer, coyotes, raptors, and numerous songbird species, making it a prime destination for wildlife enthusiasts and birdwatchers. Historically, the area was used for cattle grazing and has remnants of old homesteads and historic routes, including sections near the historic Bozeman Trail. Thunder Basin's management emphasizes multiple use, including cattle grazing balanced with conservation efforts. Visitors can explore a variety of recreational activities including hiking, mountain biking, horseback riding, and fishing in small reservoirs. The grassland's open landscape offers excellent opportunities for stargazing and photography. Several trail systems and scenic drives traverse the area, including the Thunder Basin National Grassland Main Road, offering access to remote backcountry experiences. The National Grassland is managed by the U.S. Forest Service as part of the Medicine Bow-Routt National Forests, focusing on preserving its ecological integrity while providing outdoor recreation access. Its relatively low visitation compared to national parks offers solitude and natural quiet for visitors.
