The wildlands and parks on The Irvine Ranch offer something for everyone. Come explore 50,000 acres of open space in the heart of Orange County by signing up for a variety of free public programs available throughout the year. Or help protect and manage these spectacular places by volunteering your time with us or one of our partners.

Many organizations and agencies join together to manage public activities and stewardship programs on the wildlands and parks. Most of these activities are guided programs and although they are free, advance reservations are required unless otherwise noted. Click here for more information and to sign up.

Make a difference as a volunteer! We’ll give you the training and materials you need to help others experience the true beauty and wonder of nature. Click a link below to learn more about volunteer opportunities on the land.
