Windy Run Park

If you take the wooden bridge to the right, you could technically do a loop as the top of the falls as the half way point. Just be careful as it’s steep and rocky if you go that route compared to crossing the river.

My wife and I enjoyed this trail. There is a little challenging spots when climbing and navigating through the rocks in the creeks. Overall we enjoyed it. Only downside is that there were a few places where trash was thrown.

Fantastic hike down a rocky creek, under the GW Parkway to a large waterfall and the Potomac Heritage Trail at the River. It is a bit of traffic noise from the parkway, but the solitude makes up for it

One of the best little hidden gems for a hike in the Arlington area. The trail entrance is at the end of a cul de sac so most days there’s plenty of parking. The trail is really nicely developed for being so close to DC. There’s a stream that runs through the wooded area with footbridges and railings for more difficult spots. The trail takes you under the George Washington Parkway and then to a beautiful ~35 ft. Waterfall that leads down to the banks of the Potomac. At the bottom you can split off in either direction to walk along the river. To the right you’ll have great views of Georgetown and the Key Bridge. Awesome place for a quick afternoon hike without having to go to Great Falls or Shenandoah.

One of my favorite parks in arlington! If you take the trail all the way down there is beautiful little waterfall and the Potomac! It is very much a 'natural' hike so be careful where you step!
