The best time to visit Lee Vining is typically from late spring to early autumn, roughly May through October, when the weather is mild and all the major attractions are accessible.For those keen on outdoor activities like hiking and exploring, the summer months of July and August offer the warmest temperatures and the longest daylight hours. This is ideal for visiting Mono Lake, exploring the surrounding trails, or taking a scenic drive up to Tioga Pass into Yosemite National Park, which is usually fully open by then.If you prefer fewer crowds and cooler temperatures, late May to early June or late September to early October are excellent choices. During these shoulder seasons, you'll find the scenery just as stunning, particularly with autumn colours, but with a more peaceful atmosphere.
