Parking is tough at most places along the C&O. Weekdays are best. EARLY on the weekend. Bug repellant during the season. VERY pleasant in spring and fall. Bring your camera .
ADA Accessible and newly renovated in 2019!
Come early aka before 10am to get a parking spot
If u go on the weekend, get there before 8am. The parking lot gets slammed
