The Sonoma County Trails Challenge is an invitation to discover your Regional Parks.
The Trails Challenge runs each summer and invites participants to hike, run, bike or ride at least 5 trails featured in the free Trails Challenge guidebook. The guidebook includes park notes, trail ratings, turn-by-turn directions, maps, and suggestions for themed hikes.
Finishers get a free Trails Challenge gift and also could win park memberships and REI trail gear for sharing your #SonomaCountyParks #TrailsChallenge photos.
The 2019 guidebook will be published in early June. In the meantime, you're invited to download the 2018 guide(PDF: 4.63 MB) and keep it as a resource for exploring the parks.
