"Eagle Creek, a major tributary of the North Fork Shoshone River, drains a large area across from the southeast border of Yellowstone National Park. The trail along this stream passes beneath tall peaks and ridges, goes through huge and glorious Eagle Creek Meadows, and eventually climbs all the way to Eagle Pass. At the pass you are right on the border of Yellowstone Park and a stone’s throw from Eagle Peak, which at 11,358 feet is the highest point in the park. In addition to its scenic treasures, the trail boasts the same assortment of abundant wildlife as the park, including grizzly bears, so act accordingly. Most of the 16.5 miles to the pass are quite gentle and relatively easy, with the majority of the elevation gain coming in the last couple of miles. The biggest potential obstacles are a couple of difficult stream crossings, so save this trip for later in the summer."
