Family and dog-friendly loop hike mostly along a beautiful stream
Although this is a loop hike, I strongly suggest beginning with the left or lower side of the loop. This will keep the stream on your right side the entire hike. You'll begin by crossing a small stream on a bridge - to the left of the Tucquan Glen sign.
It's an easy hike with part of it along an old logging road. Follow the blue blazes. You'll pass the remains of an old homestead. The gorge will narrow as you get closer to the halfway point and you'll have some beautiful waterfalls over huge rocks.
At the halfway point you'll reach the railroad tracks. Turn right along the tracks and cross the bridge over Tuquan Creek. After another 100 feet or so the trail will head sharply uphill on the right. The stream will be out of sight for the first third of the return trip but the trail returns to it soon.
From Lancaster take Prince Street south through town to where Rte. 324 splits off. Follow Rte. 324 until it meets River Road. Turn left (South) along River road approximately 2 miles to the Tucquan Glen Nature Preserve sign on the right.
Conversely you can get there by following River Road South from Columbia. Tuquan Glen is located between Pequea and Holtwood.
