Such long-standing businesses in the downtown area, including Stair's Grocery, Sullivan's Grocery, Clingman's Pharmacy, the oldest continuously operating pharmacy in Illinois, and Hartig Drug, closed their downtown locations. Clingman's and Hartig's relocated to the outskirts of Galena, while Stair's and Sullivan's closed their doors permanently because of competition. In late 2010, Clingman's joined the Hartig's family and moved their pharmacy to Hartig's Drugs location along Highway 20. The Country Fair in Grant Park has been an attraction that has helped increase tourist traffic to Galena as a destination. It is a craft show that attracts thousands of visitors to the area. The once boarded-up Main Street buildings have been renovated since the late 20th century. In 2010, Galena started a campaign called Vision2020, modeled after neighbor Dubuque, Iowa's Vision 2010. A committee worked on outreach efforts with the community to form a vision of what residents wanted Galena to focus on for the next decade: five major concepts have been supported. In 2010, the 32nd annual Halloween Parade attendance was estimated at 15,000. In 2011, TripAdvisor listed Galena among its top-ten "Charming Small Towns".

This area, which includes the far northwestern corner of Illinois, escaped glaciation, while almost the entire state was glaciated, nearly to its southern tip. Because it escaped glaciation, this area is known for its hills, valleys, bluffs and considerable exposed rock.
