If Leonardo DiCaprio's the Beach was set in California's High Sierra, it would be filmed here (it's that pretty). On the northern edge of June Lake is the most idyllic swimming spot. This expansive sandy beach is cradled by the spectacular shimmering lake and awe-inspiring mountains. In winter, while too chilly to swim, you'll likely have the ultimate picnic spot all to yourself.
Facilities include volleyball nets, picnic benches, restrooms and carparks. Check for road closures in winter before you visit.
