Join the Midpeninsula Regional Open Space District's 50th Anniversary Midpen Explore Challenge to learn more about the preserves in your backyard! Discover the trails, history, flora, fauna and more that can be found in the Midpen preserves with open public access.

Visit all the preserves – either virtually or in person - to complete the challenge! To participate, you must be located within Midpen district boundaries (see a map here) and give the OuterSpatial app access to your location.

To enter virtually, check in from anywhere within District boundaries and scroll through the information to learn about all of the amazing things that are out there for you to discover!

To enter in-person, head to any of the preserves to experience these wonders in the real world and check-in while you're there. At the end of 2022, everyone who has completed the challenge and checked into all 24 preserves (either virtually or in person) will be entered into a random drawing to receive a $30 gift card to the Midpen webstore.

See the full terms and conditions to learn more.

Happy exploring!
