Friends of Fair Park and the Dallas Park and Recreation Department are inviting people to join guided tram tours of Fair Park led by historian Willis Winters on select Saturdays in May, June, July, and August. The free 90-minute tours for Friends of Fair Park members and $10 tours for non-members will explore the history, art, and architecture of the 277-acre park, including murals, buildings from the 1936 Texas Centennial, and the Esplanade fountains. Space is limited and reservations are required.
