Highlight: Cave Falls
Formed by lava flows from the Yellowstone caldera thousands of years ago, the Fall River is appropriately named after its many waterfalls. What is unique about these falls is not their height, but rather their width. Cave Falls, located within Yellowstone National Park, spans 140 feet of the river and offers breathtaking views of the upper and lower falls. And, if two waterfalls aren't enough, there is a hiking trail to Bechler Falls upstream on Bechler River. This trail offers numerous campsites, fantastic views of the Grand Tetons, and access to an isolated and less-traveled section of Yellowstone National Park.

1. Cave Falls Trailhead (0 mi)
The trail begins where the pavement ends at the intersection with FR 242, Porcupine Guard Station. Beyond this waypoint is Targhee National Forest. The first section of this trail is a nicely graded dirt road but watch the speed. The potholes are very hard to see with the shadows of the trees stretching across the road.
