Access from Spiro Trail or from Silver Star Resort (parking very limited, try taking the bus).
The length of this trail varies depending upon the use it sees. Armstrong Trail is an easement graciously granted by the Armstrong family and the Park City Mountain Resort. Please respect private landowners and stay on the trail! Use extreme caution when approaching/traversing ski runs and, again, respect private land rights.
During summer months, Armstrong trail climbs through scrub oak, quaking aspen and evergreen forests to the Mid Mountain Trail at about 8,000’.
