Every year more than 10,000 people participate in this FREE self-guided hiking and bicycling program to explore our regional parks and to keep fit outdoors. The 27th annual Trails Challenge is sponsored by the Regional Parks Foundation, Kaiser Permanente, and East Bay Regional Park District. 

The Guidebook includes 20 detailed trail descriptions, available for all levels of fitness, from easy to challenging. There are trails open to hikers, bicyclists, dogs, and equestrians, and many are wheelchair accessible. To complete the challenge, hike five of the 20 trails – or 26.2 miles of trails within East Bay Regional Park District. You can also submit your log, online or by mail, by December 1, 2020 and receive a commemorative pin, while supplies lastThe pins will not be available until late June.
