Trumbull Peak Special Interest Area not only combines a rich history of fighting forest fires and logging timber, but also offers a haven for rare wildflowers and provides sweeping views of the Merced River Canyon. At the top of Trumbull Peak is an old 45-foot-tall fire lookout tower, one of only a few such towers still standing in California. The peak provides overlooks the Merced River with a clear view into Yosemite Valley. The lookout tower, built in 1934-35, offers a 360 degree panorama of the surrounding countryside. Trumbull Peak is also home to over one hundred species of wildflowers, shrubs, and trees.
