The Smith Falls Trail at Smith Falls State Park leads to Nebraska's tallest waterfall, a 63-foot (19-meter) cascade fed by a spring seep high on the canyon wall above the Niobrara River. The park is located near Sparks, approximately 15 miles east of Valentine via Highway 12 and then a well-signed gravel access road to the parking area. A Nebraska State Parks entry permit is required and can be purchased at the park entrance station or in advance online through the Nebraska Game and Parks Commission.
The trail is 0.6 miles round trip with minimal elevation gain of approximately 80 feet (24 meters), making it among Nebraska's most accessible waterfall hikes. From the parking area, visitors cross the Niobrara National Scenic River via a pedestrian bridge before the boardwalk path winds through a ferny canyon ecosystem. This microclimate supports a rare northern relict plant community — mosses, maidenhair ferns, and cool-adapted species that persist year-round in the spring-fed canyon air, contrasting sharply with the drier upland surrounding the river corridor.
Smith Falls itself plunges into a mossy amphitheater at the base of the canyon wall. The spray zone immediately below the falls is scenic but the wet rock surface is slippery; footwear with grip is advisable even though the overall difficulty is very low. A viewing platform near the base provides a safe vantage point.
The Niobrara River canyon here is a nationally recognized biodiversity hotspot where five distinct forest types converge, supporting abundant birdlife including red-headed woodpeckers, great blue herons, wild turkeys, and a variety of migratory songbirds. Canoe and kayak outfitters based in Valentine offer river float trips that can be combined with the waterfall hike for a full day of Niobrara corridor exploration.
There are no water sources on the trail itself; restrooms are available at the state park campground near the trailhead. The trail is open year-round, though spring snowmelt raises river levels and can make the wading ford alternative inadvisable — the pedestrian bridge remains usable in most conditions.

- Rare northern relict fern and moss community in the spring-fed Niobrara River canyon microclimate
- Pedestrian bridge crossing over the Niobrara National Scenic River to access the trail
- Biodiversity hotspot where five distinct Nebraska forest types converge in the river canyon
- Short boardwalk route accessible to most visitors, with a viewing platform at the waterfall base
Tips for visiting
- Wear footwear with good grip — the spray zone at the waterfall base is consistently wet and the rocks are slippery
- Apply bug spray before entering the canyon from June through August; the lush, moist environment supports dense mosquito populations
- Visit on weekdays to avoid summer weekend crowds; the short trail can bottleneck at peak times
- Consider combining the waterfall hike with a Niobrara River canoe float — outfitters in Valentine rent equipment and arrange shuttles
- Check river levels in spring before planning to use the wading ford; the pedestrian bridge is the safer crossing option at high water
When to visit
Late May through September offers the most reliable trail conditions; spring visits risk higher river levels from snowmelt. Early morning on weekdays is the quietest time, and the canyon light is most attractive in the hours before noon.
Accessibility
The trail includes boardwalk sections and a pedestrian bridge, but the overall route is not wheelchair or stroller accessible due to the river crossing approach, uneven terrain, and the slippery spray zone near the waterfall base. Visitors with significant mobility limitations will find the waterfall inaccessible.
Frequently asked questions
How tall is Smith Falls?
Smith Falls drops approximately 63 feet (19 meters), making it the tallest waterfall in Nebraska. It is fed entirely by a spring seep from the canyon wall rather than surface runoff, so flow remains relatively consistent throughout the year.
Is there a fee to visit Smith Falls State Park?
A Nebraska State Parks vehicle entry permit is required. Annual permits and day-use passes can be purchased at the park entrance or in advance online through the Nebraska Game and Parks Commission website.
Is the trail accessible to visitors with mobility limitations?
The boardwalk sections near the falls are relatively smooth, but the trail as a whole is not certified wheelchair accessible due to the river crossing, uneven terrain on the approach, and the slippery spray zone near the waterfall base.
What wildlife can be seen along the Niobrara canyon?
The canyon corridor supports red-headed woodpeckers, great blue herons, wild turkeys, and various songbirds. White-tailed deer and beaver are common. The convergence of five forest types in the canyon makes it one of Nebraska's most biodiverse wildlife corridors.
Can visitors swim at Smith Falls?
Swimming is not permitted at the waterfall. The Niobrara River in the surrounding area offers designated recreation zones, and tubing and canoeing with outfitters based in Valentine are popular activities.
