The start of spring brings a unique opportunity for a hike: The trillium-rich trails at Tryon Creek Natural Area. Accompanying the return of the robins and song sparrows, these beautiful three-petal flower are starting to bloom. The blossoms begin white and then change to a deep reddish purple as they age. These flowers are only found in moist forest settings, and mark the beginning of the new season.

The trail initially goes uphill, and then heads down to Bunk Bridge, which crosses picturesque Park Creek. In about 0.5 miles you will reach the intersection with the Middle Creek Trail. This part of the park is less travelled, and you can hear owls hooting in the misty forest.

Turn right at this intersection, and go briefly downhill to Beaver Bridge, which spans Tryon Creek, offering more pleasant views of the water. After you cross the bridge, travel 0.2 miles to another intersection with the Big Fir Trail. Continue through the forest another 0.3 miles, enjoying the trillium, until you return to the Old Main Trail. Turn left and proceed 0.15 miles to return to the Nature Center.
