Georgetown Loop is a 6.8 mile moderately trafficked loop trail located near Washington, District of Columbia that features a river and is rated as moderate. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible year-round. Dogs are also able to use this trail.
While I never completed this exact loop all at once, I walked/hiked/jogged/biked the different sections (Rock Creek Parkway south from the National Zoo, the C&O Canal, and the Georgetown University and Dumbarton Oaks areas) many times during my previous life in DC and Northern Virginia. I love Georgetown. It was a wonderful place to spend time both exploring and exercising!
