Come on up to Castle Rock and get your hands dirty for Mother Nature! The Portola Castle Rock Foundation is hosting a public workday at Castle Rock State Park in celebration of Earth Day 2026. We'll be doing some work in the native plant garden and possibly some invasive plant removal nearby. Be sure to bring lunch and a water bottle and wear weather-appropriate work clothes. All ages are welcome, but minors must be accompanied by a supervising adult. You can sign up on Squarespace or Eventbrite, and drop-ins are welcome as well! Meet at the (main) Kirkwood Entrance of Castle Rock. Rain or heavy wind will cancel this event. Event is free, parking is $10.

Tasks may include moving mulch, raking, removing invasive plants and general tidying up the Kirkwood entrance area. Open to all. Children under 18 will need a parent. Hand tools and supplies will be provided.
• Clothing – Wear layers, this park may be chilly. Wear sturdy shoes. Bring work gloves if you have them.
• Food – pack a snack or a picnic. Bring water bottles.
• Sun protection – the park can become very sunny and hot. A hat and sunscreen would be good to have.
