Milwaukee Road Rail-Trail (Thompson Park) Description

Just a few miles south of Butte, the Milwaukee Road Rail-Trail through Thompson Park offers a fun journey through two tunnels and across a trestle on the former Chicago, Milwaukee and St. Paul Railroad.

This section of railroad was one of the first in the country to be electrified; Thomas Edison even came out to Butte to ride the Milwaukee Road. The relics of this past are highlights of the trail. One of the tunnels is 550-feet long, while the other is 1,110 feet. Bring your mountain bike, headlamp and taillights for the adventure!

The trestle is a stunner, too, at 600-feet long and rising 130 feet above the valley floor. The trail ends just 100 yards from the 2,300-foot long Pipestone Pass tunnel, which is closed to the public, but you can walk up to its entrance.

If you wish to stay longer, the park offers a network of 25 miles of non-motorized trails for hiking, horseback riding or mountain biking. During the winter, the trail is also groomed for fat bicycling.

Parking and Trail Access

Take State Route 2 south of Butte for approximately nine miles. After passing Continental Drive, look for a "Recreation Area" sign and turn right onto a dirt road. Climb to the summit at Sagebrush Flats. The northernmost access to the trail can be reached from the Sagebrush Flats parking area via a trail that says "Milwaukee Road 800 feet."

To access the southernmost end of the trail, continue driving up SR 2 through multiple tight switchbacks to the summit of Pipestone Pass. Park at the top of the pass in a large pullout with a Thompson Park sign. Park at the top of the pass in a large pullout with a Thompson Park sign. This site also accesses the Continental Divide National Scenic Trail to the north and south. Take the trail heading south toward Limekiln for about 200 feet where it will junction with the trail access to the Milwaukee Road Trail-Trail. The access trail will bring you to the entrance of the closed tunnel at Pipestone Pass.
