"Tenaya is not only one of the most beautiful lakes in Yosemite, it’s one of the most accessible—when Tioga Road (the only road in the high country) is open, usually May through October. The fact that it’s easy to get to makes it one of the most popular sites in Yosemite, but because it’s located 8,150 feet about the valley floor, it’s still a lot less crowded than other attractions. The sandy swimming beach on the east end of the clear alpine lake is a favorite spot for sunbathing, with granite domes surrounding three sides. There’s also a smaller, typically less busy beach on the west end, but you’ll have to do a little wading to get there. For landlubbers, there’s an easy 2.5-mile hike around the lake."
