What to do at Natural Lands' Green Hills Preserve

  • Hike the 3-mile combined loop of the green Clarence Trail and the red trail
  • Take the easy 0.8-mile yellow trail
  • Stop at the two marked scenic overlooks
  • Walk through meadows, woodlands, and wetlands along an Allegheny Creek tributary
  • Watch for indigo buntings and other meadow birds

Green Hills Preserve is 201 acres of rolling farm fields, woods, and wetlands in Robeson Township near Mohnton, owned and managed by the land trust Natural Lands. A tributary of Allegheny Creek runs through it. The land had been slated for a 670-house subdivision before it was protected, and it opened to the public in 2012.

We come to walk. Three marked trails start from the small lot on Gunhart Road: the green Clarence Trail, 1.6 miles and moderate, which combines with the red trail for a 3-mile loop; the red trail, 1.3 miles round trip and moderate; and the yellow trail, 0.8 miles and easy. The surfaces are grass through the meadows and dirt in the woods, with grades from flat to steep, and two marked scenic views along the way. There are no restrooms or drinking water, so we bring what we need and carry out our trash.

The preserve is open every day from sunrise to sunset and costs nothing to visit. It is for foot traffic only, and dogs must stay on a leash.

About Natural Lands' Green Hills Preserve

Nestled just outside Mohnton, PA, Natural Lands’ Green Hills Preserve offers a refreshing escape for hikers, bird-watchers, families, and dog owners alike. This 785-acre nature preserve is celebrated for its gently rolling meadows, mixed hardwood forests, and open fields, all connected by a network of well-maintained, clearly marked trails. Whether you’re seeking a brief hour-long outing or a longer, exploratory hike, Green Hills delivers an immersive nature experience under the stewardship of Natural Lands, a trusted name in conservation and outdoor recreation.

Trails & Terrain

A major draw of Green Hills Preserve is the variety and quality of its trails. Visitors repeatedly praise the neatly groomed paths, which range from easy, family-friendly strolls to moderately challenging loops. Two of the most popular options include a 1.3-mile loop for those looking for a quick nature break and a 2.6-mile circuit that covers more diverse scenery. Because the trails are clearly marked, hikers can confidently set their own pace, revisit favorite overlooks, or mix and match segments to customize their adventure. The careful balance of open meadows and shaded woodland paths ensures a pleasant outing in virtually any season.

Flora & Fauna

Throughout the preserve, wildflower meadows burst into a kaleidoscope of color in spring and summer, attracting butterflies, bees, and other pollinators in lively abundance. Many visitors delight in pausing among the blooms to watch delicate fritillaries or monarchs flit from flower to flower. The adjacent woodlands teeming with songbirds contribute to an ever-changing symphony of calls—the preserve is frequently singled out as a top local spot for bird watching. Raptors such as hawks, eagles, and vultures circle overhead in the open fields, giving photography enthusiasts and birding novices alike memorable close-up encounters.

Peace & Serenity

One of the preserve’s greatest assets is its peaceful, secluded atmosphere. Even on a mild weekend afternoon, you’ll often find yourself alone on a shaded trail, accompanied only by the rustle of leaves and the distant call of a woodpecker. Families and solo explorers alike comment on the restorative quality of the landscape—a perfect antidote to busy schedules and city noise. On rare occasions, the hum of nearby highways makes itself known at select vantage points, but for most of the trails, the tranquility remains intact, inviting visitors to linger and soak in the natural surroundings.

Unique Features & Dog-Friendly Spirit

Green Hills Preserve is more than just a collection of trails—it’s a community-oriented destination with charming traditions. The NLT code-word vest program challenges hikers to uncover hidden words along each head trail; collect all the code words and you earn a cozy fleece vest, a tangible memento of your discoveries. Dog owners will appreciate the low-traffic, leashed-dog–friendly environment. Many families return regularly with their canine companions, knowing there’s plenty of room to explore without feeling overcrowded.

Amenities & Practical Information

Visitors appreciate practical touches such as the recently paved parking lot, which provides easy access even on rainy days. While there are no formal restroom facilities on the trails, the central trailhead area offers map kiosks and ample space to prepare for your hike. Some guests have expressed interest in additional benches at scenic viewpoints and improved stream crossings after droughts have left a few creeks nearly dry. These suggestions highlight the community’s commitment to helping Natural Lands continually enhance the preserve’s infrastructure.

Preparing for Your Visit

To make the most of Green Hills Preserve, plan for a minimum of 1–2 hours outdoors, depending on your chosen loop. Visitors report that even a brief hour-long hike feels like a true escape into nature. During warmer months, be mindful of insects and ticks—apply appropriate repellents and perform a thorough self-check after your outing. Early spring and fall offer cooler temperatures ideal for longer treks, while mid-summer adventures reward keen eyes with blooming wildflowers and active birdlife. Dogs are welcome on leash; please bring waste bags and be a considerate trail neighbor.
