Glacier Point Road: This scenic drive usually opens by late May or early June, but it can vary depending on snowpack.
Tioga Road: This higher-elevation road that crosses Yosemite's Tioga Pass normally opens by late June or early July, but it is affected by snow conditions and can open earlier or later some years.
High Sierra Camps: These remote backpacking camps in Yosemite's backcountry are typically accessible by early July, but snow can delay their opening.
Snow Conditions can vary significantly from year to year based on snowfall, weather patterns, and melting rates.
For the most up-to-date information on Yosemite's snow conditions, I recommend checking the official Yosemite National Park website or contacting the park's visitor center.
