How to Access Armstrong Trailhead
A local favorite, Armstrong is a 3.8-mile-long trail classified as intermediate in difficulty. Access to the trail is gained by way of a 0.1-mile walk on Silver Star Access, which also opens into Dawns, Spiro, and Silver Spur. Once on Armstrong, travelers can connect directly to Dawns and Mid-Mountain. Dawns is a comfortable 1.8-mile trek back down to Silver Star Access with additional outlets to Spiro and Silver Spur, while Mid-Mountain (a challenging 23-mile point-to-point behemoth) connects hikers and bikers to dozens of other trails throughout the Wasatch Back.
During the summer, the trail is awash in the colors of delicate Utah wildflowers, including Indian Paintbrush, Thistle, Black-Eyed Susans, and Columbines—to name a few. In the fall, the trail blazes with the fiery leaves of the quaking aspen, making Armstrong a favorite among photographers and “leaf peepers.” Regardless of the season, Armstrong loops in and around scrub oak and evergreen forests, passing the sleepy landmarks of old mining relics along the way.
Come one come all! Armstrong is highly popular with two and four legged locals (expect to share the trail with dogs and even horses just as excited to share be outside as you!). Since Park City is designated a Gold Level Ride Center by the International Mountain Biking Association (IMBA), you can also expect to see a fair share of bikers. However, Armstrong restricts mountain bikers to uphill travel only. Keep an ear open and remember trail hierarchy: horses, hikers and bikers.
Pro tip: Approach the edges of clearings carefully. You may catch a glimpse of mule deer, which frequently graze on the open ground of bare ski runs.
