Description

Constrained by a deeply cut chasm during high water, the Boulder River flows over a 100-foot precipice, creating the spectacular Natural Bridge Falls. At low water, the river used to flow under a natural rock bridge, but in July 1988, the bridge that gave the area its name, collapsed.

Paved pedestrian trail provides great views and interpretive geologic information.

Reviews

Great Day Hike

The Natural Bridge Falls is a great accessible trail. It is ideal for families, seniors, beginner hikers and plus size hikers. The loop is less then a half mile round trip. The views are spectacular. It's an excellent lunch stop on your way into the Gallatin National Forest.

This visit was done in late March. Most of the path was clear of snow except on some densely tree covered areas. Water flow was less then it is in May and June. Temperature ranged in the high 30's.
