Trillium Trail

The Trillium Trail at Boyce Mayview Park in Upper Saint Clair, Pennsylvania is an easy 0.5-mile one-way trail that features wildflowers during the Spring like endless Trillium and an abundance of Trout Lily. The trail also features an obstructed view of the Chartiers Creek.

Hike Description
This hike begins at the eastern trailhead for the Trillium Trail and heads west along the trail before reaching Birds Meadow Drive. Hikers will find the trail, most times of the year, does not have much to see other than a small obstructed view of Chartiers Creek below. During mid-April, this trail is popping with wildflowers, so much so that I personally have never seen so many Trillium in one place. We found literally hundreds of thousands of Trillium growing up and down the slopes of the hill along this trail. Along with Trillium, hikers should be able to find plenty of yellow Trout Lily growing off the trail as well.

Eventually the trail will reach the Duckbill Trail - a loop that encompasses a large swamp area - here, stay left two times in a row to hike back uphill toward the Queen Maple Trail, where this trail ends.
