RV Parks In Buffalo, Wyoming

44.3483° N, 106.6989° W

Quick Overview

Buffalo sits at the base of the Bighorn Mountains in north-central Wyoming with several RV parks and campgrounds serving travelers on the I-90 corridor, including some free camping options. The Johnson County seat is one of the most historically significant small towns in the West, known for the Johnson County War of 1892 -- a violent conflict between wealthy cattle barons and smaller ranchers that became a defining episode in the mythology of the American frontier. The Bighorn Mountains rise steeply to the west, with Cloud Peak at 13,167 feet anchoring the Cloud Peak Wilderness and providing alpine recreation that rivals any mountain range in the Rockies. The Jim Gatchell Memorial Museum in downtown Buffalo houses one of the finest collections of frontier-era artifacts in the state, with an emphasis on the Johnson County War and the regional Native American and ranching heritage. Clear Creek flows through town providing fishing and a pleasant green corridor, and the Bighorn National Forest campgrounds and trailheads accessible from Highway 16 west of town offer mountain camping, hiking, and fishing in settings that range from ponderosa pine foothills to alpine meadows above timberline. RV camping near Buffalo provides an excellent base for exploring both the mountains and the high plains, with the Powder River basin stretching east into cattle country that still operates much as it did a century ago. The Occidental Hotel in downtown Buffalo, where Butch Cassidy and other famous figures of the frontier era stayed, has been restored and operates as both a hotel and museum that captures the town's colorful past. The Bighorn Scenic Byway (Highway 16) over the Bighorn Mountains to Ten Sleep on the west side is one of Wyoming's most spectacular mountain drives. The Powder River basin stretching east of Buffalo remains working cattle country where vast ranches operate much as they have for over a century, providing a living connection to the frontier ranching heritage that the local museums document.

Traveling to Buffalo by RV

I-90 runs through Buffalo connecting to Sheridan about 35 miles north and to Gillette about 70 miles east. Highway 16 heads west over the Bighorn Mountains, climbing through Crazy Woman Canyon before crossing 9,677-foot Powder River Pass. From Casper, Buffalo is about 120 miles north on I-25 and I-90. The interstate handles all RV sizes easily through the plains terrain, while Highway 16 west into the Bighorns includes mountain grades and curves that larger rigs should approach with attention. Fuel and supplies are available in Buffalo, with additional services in Sheridan. The Bighorn National Forest campgrounds are accessible from Highway 16, with the first campgrounds appearing about 15 miles west of town. Cloud Peak Wilderness trailheads are accessible from forest roads that branch off Highway 16 and other forest roads, with conditions varying from good gravel to rough tracks. Cell service is reliable in Buffalo and along I-90 but becomes unreliable once you head west into the Bighorn Mountains on Highway 16, particularly in the canyon sections and at higher elevations. Winter typically closes Highway 16 over Powder River Pass from November through May depending on snow conditions.

Nice hosts in a clean campground. We will be back. Hint: the dryers in the laundry need new heating elements - go elsewhere if you're doing laundry.
