About This Trail

[Total: 0    Average: 0/5]

Park adjacent to the playground just after the toll gate. Walk through parking lot, passed the bathroom (stop and use it!). Once passed the large pavilion and head downhill. This is a short hike, so not need to rush downhill.
As the trail takes a sharp turn to the right, stay to the right rather than going straight downhill…trust us when we say this can erode and slide. As you head off to the right you’ll be inline with the train tunnel so if it pops out….you’ll know!
As it comes to another turn and the train overlook, turn left and merge back to the main trail. Take the platform steps down and once again switch back to the right to the platform overlook. Take a gander at stream level of the former Union Mill Dam (footer remnants). Return back the same way.

Hey! I started as a BA in 2016 because I was looking for ways to not only connect with other outdoor fanatics but to also find a way to encourage new parents and caretakers the courage and support to find ways to get outside. There is no greater joy than watching a child come alive outside! I am happy to help you find the best- for you- Trails, Parks and Epic Play areas in and around Maryland….and add some fun facts in the mix.
