Claytor Lake has a nice trail system for walking or running. There is also lake access for swimming, fishing, paddleboarding, or other activities!
Radford has a cute downtown area with a few shops and coffee spots, as well as the riverway trail along the New River. All walkable from the Highlander Radford Hotel.
Hiking, running, biking, you name it! This is a little further (about 1 hour from Dublin), but worth the trek.
An iconic Virginia hike!
For those more interested in a big city trek, Roanoke is about 45 minutes from Dublin and offers many restaurants, shops, museums, and other activities. This is also an option for a place to stay if you're up for a longer drive.
Couldn't NOT mention Lexington. About 90 minutes away from Dublin, Lexington is forever one of Lainey's favorite spots (and now Braxton's too). Take yourself on a walking tour of Washington & Lee with LexCo coffee in hand, stop at Taps for a burger, and follow it up with a Pure Eats milkshake or donut.
