Encampment River Wilderness
Here in the northernmost extension of the Southern Rocky Mountains, the Encampment River flows north out of Colorado, past the town of Encampment and into the North Platte River. Along part of the river's canyon lies Wyoming's smallest Wilderness, approximately 16 square miles, a strip less than one mile wide in the southern portion that widens to about five miles near the northern boundary. Throughout the canyon, the river runs from wild rapids to peacefully placid stretches, and is home to brook, rainbow, and brown trout (the fishing can be worth the hike). Sagebrush grows on the open slopes, and the canyon is full of riparian vegetation.
