Where We Live

From hikes and rides atop the peaks of the Blue Ridge Mountains, to navigating the taps of the BrewRidge Trail, Charlottesville boasts both urban culture and rural adventure. The pedestrian mall downtown offers local shopping, a range of restaurants from French fine dining to sushi rolls to take-away crepes, weekend farmer’s markets, and a music scene to suit tastes for both jazz piano and garage rock.
Steeped with history, Charlottesville and the surrounding area offers many landmarks of its own. 

To branch out beyond the local without leaving the city, however, there are museums like the Kluge-Ruhe Aboriginal Art Museum and the Special Collections Library at UVA. And, if you want to get out of town, DC is just two hours away and the state capital, Richmond, is a mere one-hour drive.
