It's no secret that Cumberland Valley is an outdoor mecca for hiking, biking, birdwatching, and fishing. With over 200 miles of trails, your next adventure is only a stone's throw away. This is even true in many of our downtowns, where urban living and wildlife converge. One great example is the LeTort Nature Trail.

About the Trail

The LeTort Nature Trail is a 2.3-mile out-and-back trail following a small section of the Old South Mountain Railroad bed that stretches from downtown Carlisle to Mount Holly Springs. Most of the trail winds along the LeTort Spring Run.

A Trail for Everyone

The Nature Trail is great for kids and adults. It is mostly flat and provides many opportunities for wildlife spotting and general wellness. Those walking or hiking share the trail with bicyclists.

ADA parking is found at the LeTort Park trailhead. The trail, although not paved, is also ADA accessible and there is an ADA fishing dock located near the park.

Either before or after your hike, the kids will appreciate playing at the Fort LeTort playground located inside the park near the trailhead.

History of the Trail

LeTort Spring Run was named after James LeTort, the first European to settle in Cumberland County. LeTort set up a trading post between 1713 and 1719 and operated it for over 20 years. Later industry along the trail included tanneries, mills and a distillery and a modern day quarry. Interpretive signage along the trail explains more about James LeTort, industry along the spring, and the South Mountain Railroad.

Landscape of the Trail

One of the most unique aspects of the trail is that it winds through a variety of settings, showing the evolution of industry and life in Cumberland County. Starting in LeTort Spring Park, the trailhead soon plunges into a wild setting, feeling far-removed from the town with birds singing and wildlife scurrying about. For a short section, you walk along a residential street before you reenter the wooded area. You will then approach an I-81 overpass, followed by Lamberton Middle School's student garden and you will be able to hear Union Quarry long before you see it. In between these spots on the trail you will be surrounded by woods and the LeTort Spring Run.

Birding on the Trail

Fishing on the Trail

Many people associate the LeTort Spring Run with fly-fishing. Known for wild and wily brown trout, this stream boasts 20+ inch trout. These fish are large because they're intelligent and hard to catch, even for the most experienced fly-fishermen, making fishing this stream a bucket-list experience for many.

Future of the Trail

The trail has been maintained by the LeTort Regional Authority since 1973. This group has made many improvements to the trail to maintain and enhance the experience of the many walkers, bikers, and anglers using the trail. One of these improvements was the installation of interpretive signs, with more planned in the coming years. Native plants are being added to the trailheads and new maps are being developed. Long term goals include improving connections to other regional trail facilities including the Cumberland Valley Rail Trail.
