This is one of Yellowstone’s most popular day hikes for good reason. The climb up to 10,243 feet is challenging but gradual, the peak’s slopes are known for a rainbow of wildflowers in summer, and the view from the summit is practically unmatched. You might spot bighorn sheep, black bears, or grizzlies up here—in fact, grizzlies tend to congregate on the slopes in fall to munch on whitebark pine nuts. The top approach begins from Dunraven Pass and follows a wide trail up above the tree line with ever-expanding views. From the top, you’ll see the Grand Canyon of the Yellowstone, the Hayden Valley, Specimen Ridge, Slough Creek, and even the Tetons on a clear day. There’s also a lookout on the summit, which provides welcome shelter from the often-whipping winds. You can also hike it from the Old Chittenden Road, a slightly shorter (5 miles round-trip) but steeper trail. Much of this hike is exposed to the elements, so don’t attempt it if there’s a chance of lightning.
