While there is an NPS parking lot adjacent to Thompson’s Boathouse at Milepost 0, it is a pay lot and limited to 4 hours. If you are looking for multiple nights of free parking you might consider:
1. Fletcher’s Cove — free, ~3–4 mi to Georgetown
2. Bon Air Park/Westover — potentially free, ~7–9 mi
3. Unrestricted residential street in Arlington — potentially free, but verify signs carefully
4. Rosslyn-area paid parking — very convenient but probably not free
Hopefully others in the DC area can offer some additional local options.
