New and Interesting at ACR

Docent teaching

Learn from experts. Teach children. Be outside. Become part of community that loves nature as much as you do. Docent Training starts on September 3rd!

Great Egret

ACR continues to postpone public access to Martin Griffin Preserve pending the return of nesting egrets. Programs have been moved to an adjacent canyon, ensuring that nature education programs continue as we strive to minimize human impact.
