Old Mill - Mason Creek Loop - 6.5 Miles Round-Trip

The Staunton Ranch, Old Mill and Mason Creek trails form a 6.5 mile loop through Staunton State Park. This moderate, diverse hike features historic buildings, large aspen groves and open views. Hiker-only sections reduce traffic on this route, which is particularly nice in the fall when aspens turn.

The hike begins on the Staunton Ranch Trail to the first Mill Creek trail split (.05 miles). Keep left on the Staunton Ranch Trail and begin clockwise travel on the loop.

The Staunton Ranch Tail passes the Chase Meadow Trail (.98 miles : 8,559’) and heads west towards granite rock formations with views of the Staunton Cabin District to the south (1.5 miles : 8,661’).

It passes several cabins and grows rocky up to a bridge over Black Mountain Creek to the second intersection with the Old Mill Trail (1.82 : 8,653’).

Turn right on the hiker-only Old Mill Trail, which steepens past a climbing access route to the Old Mill Site (2.57 miles : 9,092’). Enjoy intact remains of this historic collection of cabins, ranch and lumber facilities. The area is ringed by aspens with good views of needle-like granite rock formations above.

Turn right from the bunkhouse onto the multi-use Mason Creek Trail (2.6 miles : 9,110'), which passes under towering pink and gray granite cliffs before climbing away into a dense lodgepole forest.

Keep straight and drop through an aspen grove and meadow past two splits for the Bear Paw Trail (3.55 and 4.28 miles) back to the creek (5.12 miles : 8,835’). There are several easy water crossings on the next half mile.

The trail descends through mixed forest back to the Staunton Ranch Connector Trail (6.2 miles: 8,320’). Turn right and follow signs back to the Ranch Hand Picnic Area to complete the loop (6.5 miles : 8,310’).
