Local parks offer outdoor spaces for active play; they provide a common attractive space in which grandparents and grandchildren can interact and engage in physical activity. We investigated how multigenerational active spaces, which includes age-friendly outdoor exercise equipment (the Seniors Exercise Park) within six local parks in Victoria were being used by older people, their grandchildren and other age groups. Using direct observations of park visitors over three consecutive months, the number of visitors, activity interaction, type of accompaniment (e.g., intergenerational, family, group), and physical activity level were recorded and reported descriptively. An intercept survey of a sub sample of older visitors was also conducted. A total of 5,373 visitors were observed with 43.3% (n=2,327) children and 10% (n=537) older people. Older people’s most common accompaniments were within intergenerational groups (n=164, 30.5%). Within the observed intergenerational activities, 35% were older people and 45.1% children. Most people from all age groups were observed to be physically active (≥78%). Survey respondents (n=48) reported attending the park alone (47.9%) or with company (e.g., 22.9% grandchildren, 12.5% partner/friend). Approximately a third of respondents reported exercising with their grandchildren in the designated space. A large proportion of older visitors were observed with intergenerational accompaniment in local parks, with most grandparents and their grandchildren observed to be physically active. The availability of active spaces that can be used by multiple generations for incidental movements or play activities may be an attractive setting for both children and older adults to foster intergenerational interaction and physical activity engagement.
