Frequently asked questions

How long is the Black Canyon of the Yellowstone hike and how many days does it take?

The Black Canyon of the Yellowstone route is 34.75 km, or about 21.6 miles, with 813 m of climbing. Most hikers treat it as a multi-day point-to-point backpacking trip, typically spread over 2 to 3 days because of the distance, canyon terrain, and river corridor travel.

Where does the Black Canyon of the Yellowstone hike start and where do hikers park?

The route is commonly accessed from the Tower Junction area in Yellowstone National Park, on the park’s northern road network. Parking is generally at designated trailhead areas near Tower Junction rather than roadside pullouts, and overnight vehicle parking is not allowed just anywhere in Yellowstone, so trailhead logistics need to be planned carefully.

Do you need a permit to backpack the Black Canyon of the Yellowstone trail?

Yes. Because the Black Canyon of the Yellowstone is a multi-day backcountry hike inside Yellowstone National Park, overnight trips require a Yellowstone backcountry permit. Camps must be in designated backcountry campsites rather than informal spots, which makes advance trip planning important during the main summer season.

Are dogs allowed on the Black Canyon of the Yellowstone hike?

No. Pets are not allowed on Yellowstone hiking trails or in the backcountry, so dogs cannot go on the Black Canyon of the Yellowstone route. That rule applies throughout the park’s trail system, with the usual exception for qualified service animals under park regulations.

Is the Black Canyon of the Yellowstone hike hard?

The route is rated medium, but it is still a serious backcountry hike at nearly 35 km with 813 m of elevation gain. The challenge comes more from the overall length, the point-to-point format, and the remote canyon setting than from any single steep climb.

What are the main landmarks on the Black Canyon of the Yellowstone hike?

The trail follows the Yellowstone River through the Black Canyon of the Yellowstone, with steep canyon walls and long stretches of rugged river scenery. One of the standout landmarks on the route is Knowles Falls, reached roughly 10 km into the hike, where the river drops over a rocky ledge inside the canyon.

What is the best time of year to hike the Black Canyon of the Yellowstone?

The usual hiking season is summer into early fall, when Yellowstone’s backcountry trails are most reliably snow-free. Conditions can still change quickly, and Yellowstone posts current backcountry conditions and wildlife-related closures, so the best window is often mid-summer through early fall after seasonal access has stabilized.
