Potomac Waterfront regattas are held in Georgetown at the foot of the Key Bridge. The races stretch along the new riverfront park, past Washington Harbor and end at/near Thompson’s Boat Center (“TBC”).
Parking can be a challenge depending on how nice the weather is, other Georgetown events and how early you head down to the river.
NOTE: Please keep in mind that Washington DC Meter Patrols are “all-business”. If you park in a spot that is two hours you will risk a ticket if you “feed the meter”. Best practice is to move and find a second spot if you’re staying longer. There are garages along K Street but they can have odd hours so double-check availability and any “special” rates.
