Each October, the Cornerstone Kids' Ranch in Ada welcomes visitors to experience tons of seasonal activities. Bring your crew out to choose a pumpkin from the pumpkin patch, take a fun hayride or climb a hay bale castle. Looking for adventure? See if you can navigate your way through an inflatable corn maze or the indoor hay bale maze. There are also inflatable games, train rides, a petting zoo, diamond dig, pedal car racetrack, duck races and carnival games. Pack a picnic and find a cozy spot on the ranch to enjoy your meal or stop by the concession stand to stock up. From Friday through Sunday, pony rides are also available. Also, for an additional fee, there is also gemstone mining, rock climbing and zip lines.
