Discover the tranquility of wandering alone through ponderosa forests and around rocky peaks. If you're after wide open skies, head a few miles west to the Thunder Basin National Grassland, where more than a half-million acres of prairie are home to dozens of distinctive North American mammals and birds. Hike, fish, hunt, camp... or just breathe the clear Wyoming air.

Flying V Trail

This series of connected trails starts about eight miles north of Newcastle off U.S. 85, just above the historic Flying V Lodge. The mix of single-track, two-track, and skid trails is currently about nine miles long, but it’s continually expanding thanks to the efforts of dedicated volunteers. Popular with mountain bikers, the trail system is also open to hikers. It criss-crosses a 500-acre area of thickly-forested hillsides around the ghost town of Cambria, a company coal mining town that boomed between 1890 and 1928.
