The Open Space Authority helped fund Bay Area Older Adults’ "Environmental Education Park Crawl" program. The project consisted of eight four-hour walks in different parks and one wildlife lecture. Each two- to four-mile walk had an environmental theme that educated the participating adults ages 60 and older about the valley’s parks, natural resources and urban green spaces. It also included lunch, coordination of transportation, parking fees and three trained guides. Participants benefitted in multiple ways: safely walking outdoors in a group is critical in reducing the risk of heart disease, diabetes, colon cancer and depression, and learning about nature promotes cognitive health and reduces the risk of dementia.
