The largest subalpine meadow in the Sierra (at 8,600 feet) is a popular way station for backpack trips along the Pacific Crest and John Muir trails. The setting is not as dramatic as Yosemite Valley, 56 miles away, but the almost perfectly flat basin, about 2½ miles long, is intriguing, and in July it's resplendent with wildflowers. The most popular day hike is up Lembert Dome, atop which you'll have breathtaking views of the basin below. Keep in mind that Tioga Road rarely opens before June and usually closes by mid-October.
