Cincinnati Reds fanatics touring the Great American Ballpark and the Reds Hall of Fame and Museum will get an inside look at the team's storied past and present. A knowledgeable guide captains the park excursion, leading visitors to many of the park's greatest sites during the 90-minute tour, which includes visits to the dugout, the field behind home plate, the press box, and the iconic spittoon where famous players deposit chewed-up swear words. The self-guided museum tour typically lasts 45–60 minutes. This year's additions to its exhibit roster include a 2010 retrospective, a Johnny Bench tribute, and a 50th-anniversary flashback commemorating the Reds' 1961 National League Championship. Pitch a few rounds in the interactive Play Ball! exhibit, and take in a Reds history film while seated in the wooden vintage-style grandstand in the Palace of the Fans Theater. The tour's grand finale is the Reds Hall of Fame, where a panoramic photo of 1912's opening day engulfs visitors, as well as the four-sided plaque towers commemorating the Reds' greatest sports-doers and most spirited cracker-jack vendors.

Note on mlb.com fees: An additional convenience charge of $3.50 will be applied to each ticket on checkout.
