Ready to wrap up summer in style and step into fall with a challenge?
Join us for the WILD Trail Challenge, featuring five hikes over five Saturdays that will take you across every trail in the breathtaking Jack London State Historic Park. Each adventure is guided by the experienced staff and volunteers of Jack London Park Partners, who will bring the park’s rich history and stunning natural beauty to life with every step.
Each week, the hikes will increase in distance, difficulty, or for a little extra fun, sometimes both. It’s a perfect way to challenge yourself, connect with nature, and discover corners of the park you’ve never seen.
You can register for individual hikes or go all in and sign up for all five before September 6 to save 20%. Complete the full challenge and you’ll earn the title of true WILD One!
Be sure to wear sturdy hiking shoes and bring plenty of water. You’ll receive an email 48 hours before each hike with trail updates and gear tips to help you prepare.
*Please note that dogs will not be permitted on any of the five hikes. We’ll be traveling through the park’s backcountry trails and protected wildlife habitat. Thank you for helping us keep wildlife safe.
Below you’ll find pricing options and brief descriptions of each hike. We look forward to seeing you on the trails!
