Cave Falls

Overview

Cave Falls is Yellowstone’s broadest waterfall—a low, roaring curtain roughly 20 feet high and about 250 feet across on the Falls River. It feels wild and remote, far from the park’s main loops, and rewards the effort with solitude and that satisfying big-river sound. The “cave” that once gave the falls its name has collapsed, but the namesake cascade remains a quiet gem of the park’s southwest Bechler region.

Getting There

Access is from Idaho, not from Yellowstone’s main road system. Expect 14–20 miles of rough gravel/dirt road near the end—generally passable in summer for 2WD when conditions are good, but slow going. Cell service typically drops out once you’re in the mountains, so plan logistics and navigation ahead.

What You’ll See

This is a drive-up waterfall with a short walk to viewpoints at river level and above. The Falls River spreads over a broad volcanic ledge, creating that unusually wide sheet of water. It’s a peaceful place to linger, listen, and photograph without the crowds that swarm the park’s taller canyon falls.

Trails and Nearby Hikes

From Cave Falls, an easy riverside walk leads to Bechler Falls—about 2.6 miles round-trip with modest elevation change. The broader Bechler trail system also radiates from this corner, connecting to longer routes toward classic backcountry cascades. Note that a nearby Fall River ford is wide and dangerous and is not recommended.

Amenities

You’ll find a small parking area, vault toilets, and a handful of picnic tables right by the falls. There’s no running water at the picnic area; potable water is available seasonally via a yard hydrant at the nearby Cave Falls Campground. No overnight camping in the picnic area, and use only provided fire grates if present.

Activities

Anglers appreciate the cool, clear Falls River for approachable trout fishing. Some visitors wade along calmer margins, but the water is cold and swift—use caution at all times. This spot also serves as a practical trailhead for day hikers and backpackers exploring the Bechler “Cascade Corner.”

Wildlife & Safety

This is true backcountry habitat. Bears are possible along the road and trails; carry bear spray, hike in groups, and make noise. According to the National Park Service, park waters are swift and cold, river crossings are hazardous, and swimming is not recommended. Keep a safe distance from all wildlife and secure food at all times.

Best Time to Visit

Late summer into fall is the sweet spot for the Bechler region; earlier in the season trails can stay wet into September. Even in peak season, Cave Falls is typically quiet. Plan extra travel time for the gravel approach and enjoy a picnic before or after the easy walk to Bechler Falls.
