Find something fun, informative, and healthy to do and enjoy in the Regional Parks. Explore the history, culture, and natural resources in Alameda and Contra Costa counties.
Kick off the new year with the 2022 Trails Challenge! Free Trails Challenge 2022 t-shirts and printed guidebooks are now available at most Park District Visitor Centers, while supplies last. Limit of one t-shirt per person who must be present and one guidebook per family. Downloadable guidebooks are also available online.
The Trails Challenge program encourages park visitors to explore new trails by foot, bicycle, horseback, or even in-line skating! Every year more than 10,000 people participate in this FREE self-guided hiking and bicycling program to explore the East Bay Regional Parks and to keep fit outdoors. Trails Challenge is a free program made possible through a partnership between the East Bay Regional Park District, the Regional Parks Foundation, and Kaiser Permanente.
