Hartwood Acres is probably now best known for its Celebration of Lights, an event that consists of driving through the park at night to view an elaborate display of holiday lights (currently in operation, this year it is slated to run until Sunday, January 9, 2011). Donations are requested for cars traveling through the event (this year’s suggested donation is $12). For this event, visitors must enter via the Saxonburg Road entrance. The event begins at 6:00 PM every night and runs until 10:00 (on Fridays and Saturdays it runs until 11:00).
Hartwood Acres also has a summer concert series that tends to boast a wide variety of acts; these events are held at the amphitheatre near the Middle Road parking lot. These concerts are free, and if memory serves, parking is usually expanded for these events (the Middle Road parking lot is not the largest area imaginable).
