While we were in Vienna,VA we checked out Northside Park. It is a 26-acre undeveloped park with unpaved hiking and walking trails throughout. This Fairfax County park is located just off of the W&OD Trail tucked next to a nice older neighborhood.
Address: Northside Park, Vienna, VA 22180
This park is a great location to take the kids hiking/ walking through the nature trails. Also if you enjoy geo-caching then this is the perfect place for you. Northside Park is a nice natural park found in the middle of Vienna. The family and I will definitely return here to check out all the trails.
