Recreational Activities Knowles Falls

There are plenty of things to do at Knowles Falls, from camping along the way in backcountry campsites to hiking, horseback riding, white water rafting, and birdwatching.



If you’re wondering “can you swim in Knowles Falls?” the answer is unclear. Hikers have not reported swimming here specifically, but it is likely that some have.

The parks service page states that the Boiling River Swim Area (temporarily closed) and Firehole Swim Area are the only permissible swimming locations within Yellowstone NP.

It is never recommended that you swim in a waterfall due to the intense undercurrent that can sweep you away. Instead, it’s better to swim in milder rivers, streams, and lakes in the area, and obey all restrictions of the park and surrounding locations.


Yellowstone offers many boating opportunities throughout the park. The park itself has vendors within the boundaries with rentals, or you may bring your own in, or rent from a local outfitter. Boating tours are available from many companies, as well.

Trail Routes

There is one primary route to reach Knowles Falls. The trail begins at Blacktail Deer Creek Trail which adjoins it, or you can head out from Eagle Creek Campground.

Blacktail Deer Creek Trail to Knowles Falls

The Blacktail Deer Creek Trail is a point-to-point trail of 8.2 miles, leading past Knowles Falls.

Along the trail, you’ll see meadows as you climb your way toward the beautiful waterfall. The trail starts climbing half a mile from the road (there’s parking there), passing fenced-in areas which are elk enclosures.

For two miles, you’re met with the beautiful meadows filled with wildflowers all summer, then you join the Blacktail Deer Creek, going down about 800 feet to the bottom of the Black Canyon of Yellowstone.

There will be a small waterfall a few yards off the trail, and farther on a unique rock wall opposite the creek, which is a columnar basalt, which forms from the cooling of lava flows.

Eventually, you’ll come to a steel suspension bridge, which you’ll cross, and join the Yellowstone River Trail. Shortly after joining the trail, you’ll reach Crevice Lake. Finally, at the 5.5 mile marker, you’ll reach Knowles Falls.

  • Distance: 8.2 miles
  • Elevation gain: 1410 feet
  • Difficulty level: Challenging
  • Trail type: Out and back
