Mesa Falls Scenic Byway, Idaho

Upper Mesa Falls

Beginning in Ashton, Idaho, Mesa Falls Scenic Byway is a 30-mile drive leading along the Henrys Fork of the Snake River. Located just off Highway 20 along Idaho 47, the byway takes visitors through the Caribou-Targhee National Forest area on a round-about trip to see freshwater falls, bubbling streams, and scenic views of the Teton Mountain Range.

One of the main attractions of the byway is the Upper and Lower Mesa Falls, two of Idaho’s last undisturbed waterfalls. Both waterfalls can be accessed by driving short forest roads that lead to viewing platforms that overlook the rushing water. The turn off for the Upper falls will also lead to the Mesa Falls Nature Trail and the Interpretive Center, where visitors can learn about the area’s history and wildlife.

At the beginning or end of the drive, depending on where you start, is Harriman State Park, a wildlife refuge. Within the Greater Yellowstone Ecosystem, here visitors can camp, hike and fly fish in the Henrys Fork. There are also many opportunities to see wildlife like trumpeter swans, elk, sandhill cranes and many varieties of waterfowl.
