Greycliff Mill

Greycliff mill is a 1760 barn with a water powered gristmill serving espresso, BBQ, shakes and pastries. It’s a neat place to stop just east of Big Timber, MT and very close to the Big Timber/Greycliff KOA.

Natural Bridge Falls

Natural Bridge Falls is a stunning natural landmark located in the Boulder River Valley, near Big Timber. The falls were named for the natural limestone bridge that once spanned the Boulder River. Over time, the river carved its way through the rock, creating a spectacular natural bridge. However, in 1988, the bridge collapsed due to natural erosion, leaving behind a beautiful waterfall and a dramatic canyon.

Even though the natural bridge no longer stands, the site remains breathtaking. The Boulder River cascades down a series of rocky steps, creating multiple waterfalls. Depending on the season and water levels, the falls can vary in intensity, from a gentle flow in late summer to a roaring torrent during spring runoff. One of the unique aspects of Natural Bridge Falls is that during periods of lower water flow, the Boulder River disappears into the limestone rock above the falls and re-emerges downstream. This phenomenon creates a natural underground river, adding to the site’s mystique.
