Natural Bridge Falls Fishing Access Site is a Forest Service day-use area located 25 miles south of Big Timber where the Boulder River flows over a spectacular 105-foot limestone falls.

The site features handicap-accessible vault toilets, paved trails, interpretive signs, and river overlooks, with a sturdy bridge crossing for access to downstream viewing areas.

The site is free to visit and open 24 hours year-round, though no camping is permitted at the falls itself; nearby Forest Service campgrounds are available along the Boulder River Road.
