What Previous Attendees are Saying:
“I so enjoyed getting “off trail” and exploring with the Anza Borrego Foundation. The camaraderie, physical challenge, and education around Anza Borrego was beyond my expectations. I so admire the volunteers for giving back to their parks and leading these hikes. I am happy to pay for another experience and give back in my own way!”
“Great hike, great group, great ABF volunteers/staff. Todd is a good leader and a good advocate for ABF.”
