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. The 28th 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 some trails 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 submit your log, online or by mail, by December 1, 2021. Pins are no longer available.

All 20 featured trails are available on the AllTrails app. First download the free app, sign-up and log in, then go to and click on “Copy to my lists”, followed by "Continue in App". The featured trails will show under 'Lists' in 'Plan'. The app indicates where you are on the trail, enabling easy return to the trail if you stray from it. You can also record your hikes, share your photos and comments with other park users.
