Cave Falls & Bechler Area is the Hidden Part of Yellowstone that is actually in Idaho. The Bechler region is the “wettest part of Yellowstone. It is dubbed “Cascade Corner” because of the many water falls. Here you can easily see Cave Falls and if you’re up to it take a 3 mile round trip hike to Bechler Falls or a 3.2 mile hike to Terrace Falls. Be sure to check in at the Bechler Ranger Station to pick up a map and trailhead information.
Travel back to West Yellowstone on Idaho 47 or from Ashton on US 20. This trip is best taken after July 1st because part of the route travels on a gravel road that is minimally maintained.
