Lewis Falls Trail

Overview

Lewis Falls is a quick, scenic pull-off on the Lewis River, just north of the park’s South Entrance. The waterfall drops roughly 30 feet and is easily viewed from the bridge and nearby pullouts. This is more of a leg-stretcher than a true hike—short, photogenic, and on most itineraries only worth a few minutes.

Trail Details

The signed path is a 0.1-mile total out-and-back with about 29 feet of gain. Expect a brief, well-defined stroll to an overlook with guardrails. A recent rehabilitation project improved footing and clarified the route, helping curb the off-trail scrambling that used to chew up the riverbank. You can also walk the bridge for a different angle—just be alert to fast traffic.

What You’ll See

You’re here for the falls: a broad, foaming drop on the Lewis River, framed by lodgepole forest. It’s a good photo stop, especially if you like to play with shutter speed. Anglers take note: the Lewis River corridor is known for brown and brook trout—worth keeping in mind if you’re planning a separate fishing day.

Is It Worth It?

Yes—as a quick stop when you’re driving the South Entrance road. It’s not a destination hike, and it’s over in minutes, but it’s a lovely first taste of Yellowstone scenery and an easy win for photographers.

Best Time to Visit

Morning light is best, when the rising sun hits the face of the falls; later in the day portions can fall into shadow. Summer brings steady roadside traffic and brief crowd pulses; aim for early or late for fewer people. In winter, the South Entrance road closes to regular vehicles, so plan oversnow travel if you want to see it then.

Tips and Notes

• Park only in designated pullouts on either side of the bridge and watch for vehicles when crossing the road.
• Conditions can change—construction or snow may temporarily limit access.
• Stay on the rehabilitated path and behind railings to protect the riverbank and for your own safety.
