The Hemlock Trail in Laurel Hill State Park, PA, is an easy 1.8 mile out-and-back hike that leads you through an old growth Hemlock grove.
The trail runs from the parking lot on Laurel Hill Park rd next to Laurel Hill Creek over to Buck Run rd in Laurel Hill State Park.
You can fish along the creek as well and it's stocked with trout, but you need to use artificial lures per regulations and of course, need a state license.
