The aim of this study was to investigate visitor distribution by GPS tracking system at Nakhon Ratchasima Zoo. The samples were 122 participants who received GPS tracking and cycled to visit animals around the zoo. The data were categorized into two groups including demographic and travelling profile and top animal exhibit. The result revealed that the most visitors were family, while the member of half visitors were 3-5 people. Most visitors spent their time with cycling less than 2 hours and lower than 6 kilometers. Visitors scatteringly visited animal exhibits, and they often passed only half of the exhibits. Amongst total exhibits, the 51-75 % of them were popularly visited. The top 3 popular exhibits were giraffe, chimpanzee and tapir, whereas the most exhibit zone that the visitors spent total time were zoo kid zone, reptile, seal show building and chimpanzee zones. The chimpanzee zone was only one exhibit that was full of visitors and got the highest satisfaction score from the visitors, while the zoo kid and the reptile zones were lower score. Overall, visitor behaviors, exhibit appearances and animal types are crucial factors that influence the zoo visitors.
