Welcome to Trails Challenge 2023

EBRPD 2023 Trails Challenge 30 Years Anniversary

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 30th annual Trails Challenge is sponsored by the Regional Parks FoundationKaiser Permanente, and East Bay Regional Park District. 

For the past 30 years, the Park District has promoted healthy recreation and time in nature through its annual Trails Challenge program. The free program connects people to nature through hiking and biking by providing 20 designated trails ranging from easy to challenging. The Trails Challenge is part of the global Healthy Parks Healthy People (HPHP) movement that underscores the connection between a healthy green environment and community health.

The 2023 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 Trails Challenge 2023 offers increased accessibility with trails that have been evaluated and identified as usable by persons with mobility limitations (see pages 7-13).

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, 2023, and receive a commemorative pin, while supplies last.

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 'Saved'. 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 and comments with other park users.
