Trails Challenge

Welcome to Trails Challenge 2025!

For the past 32 years, the East Bay Regional Park District, in partnership with the Regional Parks Foundation, has promoted healthy recreation and time in nature through its annual Trails Challenge program. The free program connects people to nature by providing 20 designated trails ranging from easy to moderate and challenging, including a number of fully accessible trails that have been evaluated and identified as usable by persons with mobility limitations.

To finish the challenge, participants need to walk, ride, or roll five trails or 26.2 miles. Walking, biking, and horseback are all ways visitors can participate.

2025 Trails Challenge guidebooks and T-shirts can be picked up at any East Bay Regional Parks Visitor Center while supplies last. The guidebook can also be downloaded online.

Please visit www.ebparks.org/trails-challenge for more program details including instructions for picking up your free t-shirt and guidebook.

This year's Trails Challenge is made possible with the generous support of our sponsors: Kaiser Permanente and AllTrails

I notice how the hill has many dragonflies on it and how the crisp sunlight melts over the bugs, blending them in with cool shadows while the soft flowers come out from the damp forest floor. -Isla, Camper at Redwood Reinhardt Regional Park
East Bay Regional Parks are one of the best things about the Bay, I want everyone to be able to experience them. - Matt C., Member & Donor
This was the first field trip my students ever went on. The self-esteem, the joy and the fulfillment of being part of this special event supported growth and community life skills for each of my students! – Teacher at Turner Elementary in Antioch, Disability Fishing Derby Participant
