This Montour Trail and South Park Loop cycling route offers a dynamic experience, blending the smooth, generally flat crushed limestone of the Montour Trail with the more challenging, hilly terrain of the South Park Montour Spur Trail. You'll pedal through remote woodlands, past rolling farmlands, and alongside Montour Run, enjoying features like the McDonald Viaduct and the cool, lit Enlow Tunnel before tackling the steeper grades of the connector trail through mixed forests and a quiet valley. Keep an eye out for the Duck Pond as you navigate the varied landscapes.
Planning your visit is straightforward, as the Montour Trail provides numerous trailheads with parking, seasonal water fountains, and picnic shelters.

Wider tires are recommended for the crushed limestone sections, and it's best to cycle during pleasant weather to fully appreciate the ride.
This route is a fantastic option for cyclists looking to combine the classic rail-trail experience with a more rigorous workout, offering a taste of both the Montour Trail's extensive network and the unique challenges of the South Park area.
