Nebraska's Tallest Waterfall
Tucked into a fern-lined side canyon along the Niobrara River, Smith Falls drops about 63 feet, making it the tallest waterfall in Nebraska. It is the centerpiece of Smith Falls State Park, a small but beloved park about 15 miles east of Valentine off Highway 12. The falls are spring-fed, so they run clear and cold all summer, and the surrounding canyon stays green and shady even when the prairie above is baking in July heat.
For many visitors the falls are the highlight of a river day. If you are paddling, you can pull off at the park and walk up to the falls before continuing downstream. Our Niobrara River float weekend itinerary builds in a stop here.
Getting There and Fees
Smith Falls State Park sits on the south side of the Niobrara River. From Valentine, drive east on Highway 12 for roughly 15 miles, then turn north on Smith Falls Road and cross the river. Because it is a Nebraska state park, you need a valid state park entry permit on your vehicle, which you can buy at the entrance or online. There is a separate fee for crossing the day-use area if you arrive by river.
The Trail to the Falls
Reaching the falls is easy. From the parking area you cross the river on a swinging pedestrian bridge, then follow a flat, well-maintained boardwalk and path roughly a quarter mile up the side canyon to a viewing platform at the base of the falls. The round trip is short enough for young kids and grandparents alike. Take your time on the boardwalk to spot ferns, birch, and the rare paper birch stands that survive in these cool canyon microclimates.
- Distance: about 0.5 mile round trip from the parking lot.
- Difficulty: easy, mostly boardwalk and packed path.
- Time: 20 to 40 minutes with photos.
- Best light: midday to early afternoon, when sun reaches into the canyon.
Camping and Facilities
Smith Falls State Park offers primitive and tent camping along the river, which makes it a favorite basecamp for paddlers. Sites are first-come or reservable depending on the season, and the park has vault toilets, drinking water, and a small concession that rents tubes and runs shuttles in summer. Camping riverside means you can hear the Niobrara at night and get to the falls before the day crowds arrive.
Tips for Your Visit
A few things make a Smith Falls trip smoother:
- Arrive early on summer weekends, as the small lot fills fast.
- Bring water shoes if you plan to wade near the plunge pool.
- Do not climb on the falls or off-trail, since the canyon is fragile and protected.
- Pack out everything, as services are limited.
Pair It With a River Day
Most people fold Smith Falls into a larger Niobrara outing rather than visiting on its own. Spend the morning canoeing from Cornell Bridge, stop at the falls, then settle into a riverside campsite or head back to Valentine for dinner. See the full two-day plan in our Niobrara River float weekend guide.
