Naturalists at Large provides outdoor education programs for K-12 schools, accommodating groups from 15 to over 200 students. They lead multi-day trips to locations like Leo Carrillo State Beach, Joshua Tree, and Yosemite, where students explore ecosystems, identify plants and wildlife, and build outdoor skills through hiking, camping, and other hands-on activities led by certified naturalist instructors. The programs aim to foster an understanding and appreciation of the environment through experiential learning.
