For an LA take on Georgetown’s side streets or the C & O, tool around the Venice Canals. Built in 1905 just a few blocks from Venice Beach, these shallow waterways are lined with pedestrian-only paths and more styles of fantastic/weird-ass architecture than you ever knew existed.
When you're jonesing for the Mount Vernon Trail, go run or bike The Strand, a beach path that stretches 22 miles from Santa Monica to Torrance. You’re trading the winding Potomac for the sparkling Pacific, a difference you can note from any of the beachside bars along the way.
When you want a Tidal Basin vibe, head to Echo Park Lake for its fountain, pedal boats, and palm trees. In exchange for the Jefferson Memorial and cherry blossoms, check out the boathouse (which has a lighthouse and the breakfast/lunch Beacon café) and the pink lotus flowers that bloom here in July and August.
