Why you might roll your eyes:
A popular trail, it can be combat biking on nice weekends.
Why you’ll love it:
Washington has lots of great biking options, but where else can you pedal past views of the country’s most majestic monuments? You could walk or jog, but a bike allows you to cover more ground: The 18-mile trail stretches from Theodore Roosevelt Island to George Washington’s Mount Vernon. Much of it hugs the Potomac, so you get views of the river as well as of the Lincoln Memorial and Washington Monument. The path from Old Town to Mount Vernon is calmer, with scenery that includes the cattails and birds of Dyke Marsh Wildlife Preserve. To avoid crowds, bike on a weekday or early on a weekend morning.
