The mining structures at the end of the trail are remains from the Boston Mining Company, active in the late 1800s.
The trail leads into a natural glacial cirque, which protects the remains from heavy wind and provides a unique microclimate.
The area was once home to the town of Mayflower, established during the gold and silver boom of the late 19th century.
The gulch features a 'Big Hill' section near the start that is historically significant as a supply route for early miners.
The high elevation of the trail means visitors are often above the treeline, offering unobstructed views of Fletcher Mountain and Atlantic Peak.
Mayflower Gulch Trail is a 6.2-mile round-trip hike located in the Tenmile Range near Frisco, Colorado. The trail ascends toward a historic mining camp, the Boston Mine, which features preserved wooden cabins and mining equipment ruins set against a cirque of peaks. Visitors encounter an elevation gain of approximately 1,574 feet, reaching a high point of 12,175 feet. The path follows an old mining road before transitioning into a more rugged mountain trail. The gulch is known for its high-alpine wildflowers in mid-summer and expansive views of the surrounding peaks. The remains of the mine, including structures and abandoned machinery, provide a tangible connection to Colorado's 19th-century silver mining era. The site is part of the White River National Forest. The terrain consists of loose rocks and steady inclines suitable for intermediate hikers.

Bring multiple layers of clothing, as weather conditions above the treeline change rapidly regardless of the season.
Start your hike early in the day to avoid the common afternoon thunderstorms typical of Colorado high-altitude environments.
Carry at least two liters of water per person to manage the effects of high altitude and dry mountain air.
Attempting the trail without proper footwear or during the shoulder seasons when snow obscuring the path remains a significant hazard.
Trail access is often limited by heavy snowpack through late June; winter access may require snowshoes or backcountry skiing gear.
Practice Leave No Trace principles by staying on designated trails, packing out all trash, and refraining from touching or entering the historic mining ruins.
