Thunder Basin National Grassland invites RV travelers into the heart of northeastern Wyoming’s Powder River Basin, where a semi-arid prairie unfolds between the Big Horn Mountains and the Black Hills. The landscape’s gentle elevations from 3,600 to 5,200 feet create a sweeping horizon perfect for dispersed camping, OHV exploration, and scenic drives. Here, wide-open spaces and quiet nights offer a genuine escape, where you can soak in the immense sky and the simple rhythm of the land. It’s a working grassland managed by the US Forest Service, and its remote character rewards those seeking solitude without frills.
Best season — Late spring through early autumn, when prairie wildflowers bloom, bird activity peaks, and roads are generally dry. Summers can be hot and windy; spring and fall offer mild temperatures for hiking and wildlife watching.
