Tips from the Community

July 27, 2024, Uplands Trail

The Uplands Trail is a short, .7-mile, relatively easy path; however, it is rocky and uneven in some areas. The trail provides access to the Mountain Top and Log trails and offers nice elevation changes along the way. While on this route, you'll see plenty of wildlife, including deer, fox and several bird species, as you immerse yourself in the beautiful forest with trees over 100 years old.

This is all that's left of the stonework building that was once the pottery for Moravian settlers. The building later served as a cloth-making and weaving workshop, and as housing too.

The South Mountain Trails are a mix of terrain and difficulty, so worth checking for more info before riding here. The trails are generally packed earth, but are stony in places. It is a beautiful preserve, rich in wildlife and with many large boulders.
