Trails Challenge 2018

Notice: Trails Challenge 2019 will launch on January 2, 2019

Trails Challenge is celebrating its 25th Anniversary! Every year more than 10,000 people use this FREE self-guided program to explore our regional parks and to keep fit outdoors. Trails Challenge is brought to you by a partnership between the East Bay Regional Park District, Kaiser Permanente, and the Regional Parks Foundation.

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

No Registration is needed to participate. Simply pick-up or download the Guidebook and get started! The Guidebook includes detailed trail descriptions for hikes in 20 Regional Parks or Trails. Hikes range 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 trails – or 26.2 miles of trails.

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.
