A New Trail System in Princeton

Mercer County is full of open spaces and hiking trails, but if you’re looking for a fresh adventure with new views, head to the Gardner Center Trails — the county’s outdoor destination, that is also educational.

Where to Find the Trails

Located at the Mercer County Gardner Center, this 23-acre woodland space in Princeton features six hiking trails ranging from easy to moderate difficulty. The property offers over 6,000 feet of walking paths, making it ideal for families, nature lovers, and casual hikers.

Trail Overview

Four easy trails — Falling Timber Trail, Longwood Trail, Picnic Fire Pit Trail, and Poor Farm Trail — are each under 0.2 miles and connect to other routes on the property. The Mountain Laurel Trail is a moderate 0.4-mile trail with a few rocky patches, while the longest trail, the Gardner Center Trail, stretches 0.5 miles and loops around the entire center.

A Historic Site with Roots in Forestry

The Gardner Center was formerly the U.S. Forest Service’s Forestry Sciences Laboratory, built in 1963 to honor President John F. Kennedy. For decades, the site served as a hub for forestry research, where scientists collected tree samples and planted species for long-term study.

In 2020, the Mercer County Commission acquired the property to preserve both its ecological and historical significance. The original stone-bordered trails remain intact, and informational signage shares details about the site’s legacy.
