About Knowles Falls

Knowles Falls sits within the boundaries of Yellowstone National Park and is managed by the National Park Service, making it a quietly scenic stop in the park’s Montana portion. While not one of Yellowstone’s marquee attractions, the falls reward visitors who seek a more secluded stretch of river and forest — perfect for photographers and hikers looking to escape the busiest overlooks. Yellowstone, established in 1872 as the first U.S. national park, protects wide-ranging landscapes, and Knowles Falls is a subtle example of the park’s less-visited natural character. Access to the falls is along a 2.4-mile out-and-back trail that climbs roughly 350 feet and is rated moderate, so it’s a doable half-day outing for most hikers who are comfortable with uneven footing and some route-finding. If you’re camping nearby, Eagle Creek Campground in the Custer Gallatin National Forest lies about 7.6 km from the trailhead and makes a convenient basecamp for a multi-day visit.

The Setting

Knowles Falls sits at 5,502 feet within Yellowstone National Park, fed by the Gardner River, in the high mountains of Montana.

Nearby Falls Worth Visiting

Osprey Falls (150 ft) lies 7.1 miles to the southwest. Also nearby: Wraith Falls (79 ft, 5.4 mi) and Undine Falls (60 ft, 5.2 mi).

Trail & Hike Details

The Approach

The moderate 2.4-mile out-and-back trail gains 350 feet of elevation on the way to the falls.

Trail Description

Trail stats: 2.4 miles total (out-and-back), approximately 350 feet of elevation gain, difficulty: moderate. The route is an out-and-back hike through park-managed terrain in Yellowstone National Park (NPS). There is no USFS trail number for this route because the feature and access sit on National Park Service land rather than a U.S. Forest Service unit. Trail conditions can be variable: expect uneven footing and sections that require basic navigation, so bring a map, wear sturdy footwear, and allow extra time for slower footing. The nearest formal campground is Eagle Creek Campground (Custer Gallatin National Forest), about 7.6 km away, for those planning an overnight stay; beyond that, services are limited, so carry water and be prepared for backcountry conditions.

What to Expect

Visitors can expect a tranquil and remote waterfall surrounded by natural beauty. The area is relatively undeveloped, so amenities are minimal or nonexistent.

Accessibility

The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.
