The 54± deeded acre Castle Rock River Ranch includes about a third of a mile of Stillwater River frontage for trout fishing, pine-covered hills, towering rock formations, and meadows. The property is in two parcels contiguous to 80± acres of State Land and 680± acres of BLM land. A one-bedroom, one-bathroom, 1,572± SF log and rock main home, and one-bedroom, one-bathroom, 509± SF log guest home sits on the property's northwest side, right on the river. The property also includes a 30'x60' log and river rock horse barn and stable, a horse shelter, a wood round pen, and four horse pastures, perfect for the equestrian. Sitting just east of the majestic Beartooth Mountains, the property is just down the road from Custer National Forest, which includes one of the wildest and most beautiful blocks of roadless land in the United States, the Absaroka-Beartooth Wilderness, home to Montana's highest peak, Granite Peak, measuring 12,807± feet. Yellowstone National Park borders the Absaroka-Beartooth Wilderness and extends south beyond Jackson, Wyoming. Encompassing an estimated twenty million acres of some of the wildest country in the world, the Greater Yellowstone Ecosystem is one of the most wildlife-rich areas on earth. Not surprisingly, hunting in this area is tremendous due to the amount of big game, including very high-quality elk.
