Big Woods Hiker-Biker Campsite is a primitive, no-fee campsite located at mile 82. 7 on the C&O Canal towpath in Washington County, Maryland, offering privacy as it sits set back from the main trail with access via a marked path.

The site accommodates up to eight people per night on a first-come, first-served basis and includes a portable toilet, picnic table, and grill, though water (non-potable and located a quarter mile downstream) is only available mid-April through mid-November and must be treated before use.

This walk-in, tent-only site is ideal for hikers and cyclists traveling the canal route seeking a secluded overnight stop.
