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.

HLS014
Location: 44.277836, -110.526066
The switchbacks end here as you gain the ridgeline. Leaving behind fallen lodgepoles, you’ll weave between sweet-scented Douglas fir and towering Engelmann spruce as you grab your first aerial views of Heart Lake and the expansive flatlands to the east.
HLS015

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

Begin taking in stunning panoramas as you continue your ascent.
Barren Hillside
Location: 44.269053, -110.535296
Just hundreds of feet after taking in panoramas of a fertile green valley, you’ll catch drastically different views, like this vista of a barren, fire-scarred hillside peppered with burn-stunted trees.
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.
Mount Sheridan Hut
Location: 44.267764, -110.532757
Perched at the summit of Mount Sheridan, this hut serves as a beacon for hikers hitting the mountain’s home stretch.
High-Alpine Environment
Location: 44.267677, -110.532373
