More than 600,000 acres, or roughly 1,000 square miles. It is the largest state park in California and the third largest in the United States, spanning parts of San Diego, Riverside and Imperial counties.

How much does it cost to enter Anza-Borrego?

Day use is $10 per vehicle, collected at the Visitor Center, developed campgrounds and several popular trailheads including The Slot and Hellhole Canyon. The park has no entrance gates and much of it can be accessed without a fee.

Annual wildflowers can appear from January through mid-April, with peak bloom most often between late February and early April. Timing varies year to year based on rainfall and temperature.

OpiCure Ascent to Freedom ride: Uniting community to honor recovery

By OpiCure Foundation • November 10, 2026

This is more than a bike ride. The OpiCure Ascent to Freedom Ride in Borrego Springs takes place Saturday, November 21, and brings together riders, friends, families, and the recovery community for a full day of connection and celebration, in association with Hazelden Betty Ford Foundation. Join the ride through the desert, jump into the pickleball tournament (all skill levels welcome), and enjoy meals provided for the riders as we come together to mark sobriety, share stories, and support one another. Whether you’re riding, playing, volunteering, or simply showing up, you’re part of this. Come be part of something bigger than any single activity — come be part of the Ascent to Freedom. “We wanted this to be a fun day that everyone can enjoy. Come meet the Opicure Community and grow with us,” says OpiCure Foundation President Cullen Easter. In the heart of the Anza-Borrego Desert, this inaugural OpiCure event brings together people in recovery, their families, and the cycling community to celebrate sobriety, share stories of strength, and raise awareness about the opioid crisis. "By turning the simple act of riding into a collective ascent toward freedom, it shows that recovery is possible, community heals, and every pedal stroke can move us closer to a life beyond addiction," says Cullen. "The OpiCure Ascent to Freedom is about community, movement, and celebrating recovery in every form." OpiCure Foundation is a 501(c)(3) Non Profit Foundation focused on addressing opioid-related addiction and deaths. More information on the event is available at opicureride.com .
