Green Friday promotes fitness and fun in County parks. Events are active and educational – aligning with our mission to balance recreation with efforts to protect and preserve land and local environment. Activities are open to residents and visitors of all ages, interest and abilities, and there is no cost to attend.

On Friday, Nov. 28, 2025 - Green Friday - all of our $5 park day-use fees (where they are charged) are waived! Here's some additional information. Scroll down for a list of programs happening on Green Friday and through the holiday weekend.

STORY TRAILS

We will once again partner with the San Diego County Library to place book pages on signs along some of our more popular, kid-friendly trails for #GreenFriday, so you can walk, talk and read your way through our parks! Books vary by location, with some in English and Spanish, and will be up through the Thanksgiving holiday weekend.

List of locations - coming soon!
