Towpath Trail closed: Boston to Lock 29
The Towpath Trail is closed from Boston Trailhead to Lock 29 in Peninsula during the August 24–November 20, 2026 work period.
- NPS is replacing the wooden Stumpy Basin boardwalk as planned work before its deteriorating underside becomes a safety hazard; the 1991 boardwalk has reached the end of its serviceable life. The replacement will add space to pull off and enjoy the view.
- NPS also lists a tentative March 29–April 21, 2027 closure for further improvements.
Check current park conditions before traveling.
