Let the crowds wait for Old Faithful: Experience the rugged side of Yellowstone National Park by trekking past steaming creeks and old-growth lodgepole en route to the sprawling Heart Lake and the regal Mount Sheridan on this 23.1-mile out-and-back.

From the trailhead, hike northeast along Heart Lake Trail. The path weaves through lodgepole forests (singed in the 1988 Yellowstone fires), passing the occasional fumarole and hot spring along the way. After 7.3 miles on the flat, well-maintained path, you’ll hit the Heart Lake Ranger Station before reaching the shores of the colossal lake just minutes later. At the Y-junction, follow Heart Lake Trail around the western edge of the lake and spend the night at one of the lakeside campsites (reservations required).

Day two: Tackle the hardest section of the trip—a 3.5-mile scramble up Mount Sheridan. The route starts with a switchback climb through a fallen lodgepole field and ends with a traverse through Engelmann spruce along the mountain’s ridge. At the summit, take in sweeping panoramas of Heart Lake, as well as glimpses of Yellowstone, Lewis, and Shoshone lakes; the Absaroka and Teton ranges are perched majestically in the background. When you’ve had your fill, turn around to begin the trek back to your campsite and the trailhead.

Location: 44.31826, -110.56042

Enter an old-growth forest crammed with 40-foot lodgepole pines; continue pushing eastward.


Location: 44.310491, -110.532932

Continue feasting on increasingly awe-inspiring views while you tread carefully between trees and a harrowing hillside on the shoulder-width (and completely exposed) ridge.


Location: 44.266381, -110.529888

Before crossing this ankle-turning rock field, take in northern views of the spiny ridge you just traversed. The summit lies just 0.1 mile ahead.


Location: 44.266106, -110.52922

Crest Mount Sheridan’s 10,308-foot summit, and enjoy mind-blowing, 360-degree panoramas of Yellowstone.

Gazing northward, you’ll catch glimpses of the sprawling Yellowstone Lake in the background, while Lewis Lake and Shoshone Lake are visible to the west.


Location: 44.265359, -110.528662

The Heart Lake Trail runs parallel to Witch Creek for much of the journey to the lake.

Witch Creek

Location: 44.302587, -110.519996

Likely given its eerie moniker for the ghostly vapors that it emits, Witch Creek follows the Heart Lake Trail as it weaves toward the lake.

Steaming Stream

Location: 44.298094, -110.515822

Mountain Bluebird

Location: 44.297509, -110.509423

Burn Damage

Location: 44.268915, -110.535218

Though the scars of a forest fire may be unsightly, they are actually beneficial to the environment, enabling reforestation and regrowth.
