Getting there

Upper Mesa Falls sits about 10.0 miles northeast of Ashton in Fremont County. Navigate to the coordinates 44.18797, -111.32995, which mark the waterfall itself; the trailhead or parking area may be some distance away.

Open directions in Google Maps or Apple Maps, or view the map on the Upper Mesa Falls listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

Ownership in Idaho varies by region. Shoshone Falls is a city park in Twin Falls, while canyon falls around it mix city, state, private and federal land. Jump Creek Falls is on Bureau of Land Management land. In the mountains, most falls sit in national forests such as the Caribou-Targhee, Boise, Payette, Salmon-Challis, Nez Perce-Clearwater and Idaho Panhandle. Expect long gravel roads, seasonal closures and patchy cell service in central and north Idaho. Hazards include cold, swift snowmelt rivers, unstable basalt and canyon rims without railings, and slick rock in spray zones. Wildfire activity and smoke can close areas in late summer. Carry a paper map and plan fuel stops in remote counties.

What to bring

This checklist is tailored to Upper Mesa Falls based on what visitors report and the conditions typical of Idaho. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 44.18797, -111.32995 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Camera and a small tripod. Visitors have shared 1,865 photos of it; a tripod lets you shoot silky water in low light.
• Warm layers. Northern and mountain weather changes quickly; spring and fall mornings can be near freezing.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Snowmelt makes late spring the peak season across Idaho. In the Snake River Canyon, Shoshone Falls usually runs fullest from about April into early June; later in summer, upstream diversions for irrigation can reduce it to a fraction of its spring volume. Mesa Falls and the Panhandle falls generally peak in May and June as mountain snow melts. Central Idaho's higher-elevation falls may not be reachable until roads and trails clear of snow, often in late June or July, and flows remain decent through midsummer. Late summer and early fall bring lower water, smoke from wildfires in some years, and fall color in the northern forests. Winter is quiet; some canyon falls form ice, but many mountain roads are closed or unplowed. 466 Google reviews make it a well-known stop. Weekday mornings are the quietest time to visit.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

Henrys Fork and Eastern Idaho. On the western edge of the Yellowstone region, the Henrys Fork of the Snake flows off a high volcanic plateau and over two major drops. Upper Mesa Falls has a viewing platform close to the brink, and Lower Mesa Falls is seen from an overlook downstream, both along a scenic byway through lodgepole pine forest. South of Idaho Falls, Fall Creek Falls in Bonneville County spills over travertine ledges directly into the Snake River in Swan Valley. Caribou County, in the mountains of the southeast, rounds out this region. Snow lingers at these elevations, and access roads can be closed or unplowed in winter.
