Nestled within the scenic corridor of Seneca Creek State Park, this open-air gravel and dirt surface lot provides direct access to one of Montgomery County’s most picturesque trail networks.

Visitor & Driver Tips

The lot operates on a dawn-to-dusk schedule aligned with standard Maryland State Park regulations. As a rustic trailhead lot, spaces are unlined and available on a first-come, first-served basis; visiting early on weekend mornings ensures an easy parking space. Since this is a natural recreation area, visitors must practice Leave No Trace principles and carry out all trash. There are no permanent restrooms, trash receptacles, or running water at this specific pull-off, so plan accordingly by bringing personal hydration and supplies. Exercise caution when turning into and out of the lot, as vehicular traffic on Darnestown Road (MD-28) travels at 40–50 mph.
