Trails Challenge 2019 - Archive


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. Trails Challenge is sponsored by the Regional Parks Foundation, Kaiser Permanente, and East Bay Regional Park District.

The free printed Guidebooks and T-Shirt are available at participating Visitor Centers while supplies last.

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. You can also submit your log, online or by mail, by December 1, 2019 and receive a commemorative pin, while supplies last.

NEW! All 20 featured trails are now 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, and share your photos, comments etc. with others.

In addition to this self-guided program, we offer many naturalist-led hikes throughout the year.
