It's time to plug into something better!

Join us as we kick off our 2026 Hike-A-Thon in San Diego! Weather conditions are just right to embark on some of the region’s best trail adventures. Attend this event to learn how to register for the Hike-A-Thon, join a team and begin tracking your mileage.

We'll be partnering with County of San Diego Parks and Recreation, CAL Volunteers and Live Well San Diego to celebrate our Hike-A-Thon Kick-Off and Climate Action Day! Hundreds of volunteers will be on-site to engage in climate action service projects throughout the park.

The speaker program begins at 9:30am at the PQ Ranch House, followed by our first ranger-led hike and trailside cleanup along Los Penasquitos Creek. After that we'll have a nature and wellness fair. Free and family-friendly.
