Early childhood and kindergarten programs at Oak Grove reflect their gentle, holistic approach by integrating physical activity into the curriculum. Toddler and preschool playgrounds provide space to move, run, climb, swing and explore. Throughout the natural campus setting, walking trails and grassy fields open possibilities for hikes, cooperative games, dance and movement.

Elementary students begin a formal physical education program two days a week. This expands to four days per week in third grade, when individual and team sports are introduced alongside group games, movement and body awareness. Competition is not the focus at this level, but is seen as a springboard for discussion and introspection. Third- through sixth-graders wrap up the school year with a four-day outdoor adventure. Seventh-grade students travel to Big Sur, and eighth-graders head to Mexico for camping, ocean sports and environmental service projects.

As members of the Condor League, Oak Grove High School students participate in team volleyball, soccer, basketball and tennis. Outdoor education at the high school level is more advanced, often spanning the curriculum and bringing together physical education, academics, community service, and the arts.

High school outdoor education programs include a fall all-school trip designed to bring the high school together in order to orient and integrate new and returning students and teachers. Typical destinations are Yosemite National Park, Big Sur or the American River, and include activities such as kayaking, backpacking and nature studies. A spring trip is curriculum-based at grade level and planned by the faculty. Freshmen and sophomore trips have included geological expeditions to Death Valley, Anza Borrego or Yosemite, cultural excursions to Baja, Mexico, and marine research of the coastal islands. Juniors traditionally go on a Southwest trip, which includes exploration of Native American cultures.
