Even during a short visit, your class may have time to explore at least one of Yosemite's trails. Each area of the park offers something different with trails that range from easy to strenuous. In Yosemite Valley, many classes explore the Lower Yosemite Fall trail, the Cook's Meadow trail, Mirror Lake, or the Happy Isles area. All of these are easy trails with a one hour or less roundtrip time, though they may require a shuttle ride or brief walk to the trailhead.
Yosemite Valley is one of the more popular areas for classroom visits. In addition to many short trails, group can explore a variety of places, including visitor center exhibits, a reconstructed Indian village, Indian Cultural Museum, a free park overview film, and many other activities.
A popular area for classrooms visiting from Fresno or other areas south of the park during spring, summer, and fall, students can stroll through some of the largest trees in the world. These amazing and unique trees inspired the beginnings of land conservation leading to the national park idea.
