Union Falls

5.0Free

Experience Yellowstone's stunning second highest waterfall deep in the backcountry.

Standing at 250 feet tall, Union Falls is the second-tallest waterfall in Yellowstone National Park, formed where Mountain Ash Creek and Union Falls Creek converge. Tucked away in the park's remote southwest Bechler backcountry, this spectacular cascade plunges over a dramatic cliff into a lush canyon. Reaching Union Falls requires a strenuous multi-mile hike involving stream crossings, offering an uncrowded and unforgettable wilderness adventure.

Quick tip: Pack water shoes for river crossings, carry bear spray, and start early to complete the demanding 15-plus mile round-trip hike.
