This spot along the Cedar River Trail is a great spot to stop and view the river or take a break just below the overpass for South Jones Road.

The Foothills Trail parallels the Carbon River for many miles, but your view is often obscured by foliage. Here you get a clear view of the river from the trail, as well as the verdant flora overhanging its banks.
