Tongue River Reservoir Campground

Decker campers are around an hour’s drive from Lodge Grass, where you can find a supermarket for stocking up on supplies. There’s also a gas station here if you need to fill up your RV rental and a health clinic in case of any emergencies. While camping at the Tongue River Reservoir Campground, be sure to visit the Rosebud Battlefield State Park, which lies around 25 minutes’ drive to the north. It preserves part of a battlefield involved in the 1876 Battle of the Rosebud, where Lakota Sioux and Cheyenne tribes attacked United States Army forces under the command of General George Crook. It marked a turning point in the Great Sioux War when Native American tribes were being forced onto reservations. There’s an information kiosk where you can learn more about the battle before walking through the site’s rolling prairie framed by ridges and the Rosebud Creek. Continue driving northwest, and you’ll arrive at the Little Bighorn Battlefield National Monument, which is located near Crow Agency. It preserves the site of the 1876 Battle of the Little Bighorn between George Armstrong Custer’s 7th Cavalry and combined Lakota, Northern Cheyenne, and Arapaho forces, and acts as a memorial to those who fought and died during the battle. Wander between the monuments honoring the U.S. troops, Crazy Horse, Lame White Man, and Noise Walking at the location where these warriors fell, then explore the Custer National Cemetery that forms part of the national monument. Camp in an RV near Decker and make a day trip to the Yellowtail Dam, which was constructed across the Bighorn River in the 1960s. Aside from regulating the flow of water for irrigation purposes, the dam, its reservoir, and the river are now popular recreation destinations and one of the finest wild trout fisheries in the United States. Stop in at the Yellowtail Dam Visitor Center to browse the exhibits about the dam’s construction and the unique geology of the area while learning about the life of Robert Yellowtail, a Crow tribal leader after whom the dam was named. Whether you want to explore the historic battlefields of Montana or discover its natural wonders, book an RV in Big Horn County and start planning your next vacation.
