The Mesa Falls Scenic Byway begins at the junction of U.S. 20 and Idaho 47, the northern termination of the Teton Scenic Byway in Ashton, Idaho. From Ashton, the route travels through the Warm River area towards its main attractions, Upper and Lower Mesa Falls.
At 114 feet and 65 feet respectively, the Upper and Lower Falls offer equally spectacular views in a beautiful forest setting. Both falls can be viewed in full, Lower Falls from a quarter mile distance, Upper Falls is enhanced with pathways, with pathways, stairs and viewing platforms. These improvements lead visitors to the brink of the falls, close enough to feel the power of the cascading water. Some of the pathways and viewing platforms are universally accessible. The historic Big Falls Inn at Upper Falls has been restored to its original splendor and it is now open seasonally (approximately May 15th thru October 1st) as an interpretive center.
Though the byway is less than an hours diving time, viewing the falls, touring the interpretive center, enjoying a picnic lunch and making stops to view wildflowers can easily fill half a day.
