Gardner River, Yellowstone National Park: Glacial Valley, Boiling River Geothermal Feature, and Sheepeater Canyon

Q: Is it worth the 6-mile hike just to see a lake?

The Gardner River offers multiple payoffs: dramatic canyon views, Osprey Falls, and access to thermal inputs; the hike to Osprey Falls is worthwhile for the payoff of the fall and the geothermal context.

Q: Can I bring my dog to the thermal area?

Dogs are restricted in sensitive thermal and wildlife areas; keep pets on designated trails and away from geothermal features to prevent harm.

Q: Will my 65-year-old mother be able to walk to the viewpoint?

Yes, some viewpoints are roadside pull-offs; others require short to moderate hikes. Plan a route with accessible overlooks and allow extra time.

Q: Is the water actually blue, or is that just in photos?

Water color varies with mineral content and turbidity; some stretches appear bluish in bright light, while sediment after storms can dull the hue.

Overview

About This Attraction

A river winds through a basalt canyon and broad subalpine meadow, with Sheepeater Cliffs looming above. Gardner’s Hole sits like a natural amphitheater as the stream carves downstream toward Gardiner. This is erosion in action—water wearing rock and shaping the landscape over time.

Best Time to Visit

Late June through October; morning light enhances Osprey Falls and canyon walls; golden hour along the cliffs adds warmth to the basalt tones.

Visitor Tips

Look for flow lines and striations on the Sheepeater Cliffs as a record of long-term rock fracture and rock-water interaction.
Stay back from edges; rock along the riverbank is friable and can crumble.
Water is cold and can rise quickly after rain or snowmelt; plan exits before weather shifts.
Bear spray and sturdy footwear are essential; travel with others when possible.
In winter/early spring, traction cleats may be needed; access points shift after the 2022 floods.
