Wilmington is Delaware's largest city and is a lively destination that features the perfect blend of relaxation and fun, and at the Wilmington Riverfront, you can walk the 1.3-mile stretch of the Christina River and stop for a bite to eat at the many restaurants around. Because I-495 and I-95 run through Wilmington's borders, you'll have no problems getting in and out of town once you've used these RV dump stations in Delaware.
