Background: Providing public access to exercise and play is vital for health promotion across populations. We evaluated the use of and satisfaction at Trojan Park, a multigenerational playground with multiple activity areas and fitness zones in the city of Wellston in St. Louis County, MO. Methods: We used video footage and the System for Observing Play and Recreation in Communities (SOPARC), which is a valid and reliable system for collecting data on physical activity in parks. We then performed intercept interviews to gather user information and measure overall satisfaction with the park. Results: The park received a variety of attendees across age groups, with children and middle-aged adults representing 41.1% and 50.3% of total park users, respectively. During the time observed, 47% of attendees were engaged in moderate to vigorous physical activity (MVPA), 22% were engaged in light physical activity (walking), and 30% were sedentary. We also observed participants spending the most time on the basketball court (38%), playground (28%), and picnic (17%) areas. Park users traveled a wide range of distances to access the park and the overwhelming majority reported a high level of satisfaction. Conclusions: Our findings demonstrate that multigenerational playgrounds with access to various activities and fitness zones may provide social and physical health benefits.
