Embark on a scenic mountain biking adventure through the rolling hills and pastoral landscapes surrounding Hacklebarney State Park from Far Hills. This route, while not entering the park's rugged glacial valley, offers a blend of paved and unpaved sections, taking you through picturesque "horse country" with views that change from open fields to tree-lined roads. Expect a rewarding experience for those who appreciate varied terrain and a good workout.
Planning your ride requires noting that mountain biking is generally not permitted on the trails within Hacklebarney State Park itself; this 27.6-mile (44.4 km) loop utilizes surrounding roads and gravel paths. With 1438 feet (438 metres) of elevation gain and an estimated duration of 3 hours and 6 minutes, this moderate route is best tackled by riders with good fitness. Starting from Far Hills, ensure you're prepared for some unpaved sections that may require dismounting.
The Hacklebarney State Park area is known for its diverse habitats and a rich history, including its past as a 19th-century iron ore mine site. While the park's interior is a haven for hikers and anglers with its hemlock-lined ravine and the brisk Black River, this cycling route provides a different perspective of the region's natural beauty and challenging topography, offering a blend of natural beauty and historical context in the wider Far Hills area.
