Seneca Creek Greenway Hike Series Kickoff -- Part 1 of 5: Seneca Creek Greenway Southern Terminus: River Road to Black Rock Mill! A Moderate 6.5 Miles

This hike is located only 25 miles from DC and near Great Falls, MD.

This five-part series takes you along the entire length of the 25-Mile Seneca Creek Greenway, the Schaeffer Farm Trails, and around Clopper Lake for a total approximately 30 miles.

Description for Seneca Creek Greenway Hike Series Part 1: The Trail's Southern Terminus to Black Rock Mill

This is the lower leg of the 25-mile Seneca Creek Greenway Trail, from River Road to Black Rock Mill. From hunting grounds for the Seneca Indians to the powering of gristmills and sawmills, Seneca Creek has long served a variety of human activity. When this first leg of the 25-mile-long Seneca Creek Greenway Trail opened in 1995, it marked a new twist in the stream's narrative. Survival and industry may have driven past uses, but today it is the appetite for recreation and nature-viewing that is fulfilled by this long trail that we break down into sections, including two areas within the State Park area of this trek – the Schaeffer Farm Area and the Clopper Lake loop bringing all legs of this hike to 30 miles.

Initially, Seneca Creek became well known to English settlers, not for the stream itself, but the red sandstone found nearby. It was prized because it was a rock easy to mine. It came out of the ground soft and pliable, but the longer it was exposed to air, it would harden and form a most sturdy and reliable foundation.

The highlight of today's trek is the still visible, and visibly dramatic, stone walls of Black Rock Mill, which is at the end of this one-way hike!

Mid-Atlantic Hiking Group's Seneca Creek Greenway Hike Series Information and Details

Mid-Atlantic Hiking Group's five-part series of day-hikes takes you along the entire length of the beautiful and very biodiverse 25 mile-long Seneca Creek Greenway, Schaeffer Farm Trails, and around Clopper Lake (within Seneca Creek State Park) for a total distance of approximately 30 miles. Dividing the long trail into more doable sections helps make this a more inclusive hike versus only offering it as one very long day-hike. Also, it provides an opportunity for more people to enjoy the plentiful bounty of health benefits of hiking by encouraging participation in part of a series of hikes offered with as close to equal intervals as reasonably possible.

NOTE: Mid-Atlantic Hiking Group will issue a certificate of completion to hikers who complete all five parts of the series!
