Cruising the Potomac

1
Stay at The Graham Hotel Georgetown, where the restaurant is organic and the rooftop deck's broad views of the city will give you the lay of the land.
2
Strike out west on M Street for a twenty minute walk across the bridge to Foggy Bottom's Blue Duck Tavern where you'll enjoy a farm-to-table brunch of classic American country dishes. The service is excellent, so be sure to ask your servers about where they source their produce and artisanal cheeses.
3
After brunch, walk south down to the water where you can rent kayaks at $12 an hour at the Thompson Boat Center. Cruise up the Potomac River to Theodore Roosevelt Island, beach your kayaks, and take a stroll around the marshes for some bird-watching.
4
Return to the city for early dinner and drinks at Baby Wale in Mt. Vernon Square, with a huge space, tons of natural light, and a large tree suspended in the dining room. 
5
After dinner head back to Georgetown to catch the sunset on the water at Georgetown Waterfront Park, and enjoy views of Key Bridge and the Kennedy Center.
6
Walk home along the C&O Canal Towpath and enjoy the views of this historic waterway. Get to bed early so you have plenty of energy for tomorrow's hikes.
