The redwoods at Sequoia National Park don’t produce autumn foliage, but many of the understory plants do. Dogwoods, ferns, and blue oaks provide a colorful contrast to the evergreen trees. Head to one of the less trafficked areas of the park, the 7,500-foot high Mineral King Valley, to see the cottonwood and aspen groves blaze yellow.
