Cabin John Creek

Cabin John Creek is a waterway that extends roughly 11 miles through Montgomery County and connects with the Potomac River. The stream flows through several parks and wooded areas that define its valley and preserve its natural character.

The waterway was documented in land records as early as 1715 under the name Captain John's Run before gradually changing to Cabin John Creek. This name evolution reflects the long human connection to this water course.

The creek is woven into residents' awareness of water quality and local ecosystems, with volunteers dedicated to its protection. Communities use this waterway as a place for nature education and family outdoor activities.

A marked trail alongside the waterway offers walking routes through multiple parks and nature areas with different landscapes and features. It helps to scout the route beforehand to find your preferred starting point and best time to visit.

The creek flows beneath the Union Arch Bridge, a historic stone arch structure that carries MacArthur Boulevard and spans the Washington Aqueduct. This engineering feature uniquely joins infrastructure with natural water landscape.
