Parents, you're welcome to fill out trails logs for your children, and we'll send you instructions for also getting a free nature-themed kids' book from the Sonoma County Library.

Keep Hiking

If you're having fun, pick another 5 trails and take the Trails Challenge again. If you hike each of the 15 featured parks in the Trails Challenge guide, you'll cover more than 50 miles! If you log the all-park challenge, you'll be eligible for special giveaways when the Trails Challenge ends.
