The distance between Mammoth Lakes, CA, and Sunnyvale, CA, is approximately 300 to 320 miles, depending on the route you take.
Driving Routes:
- Via US-395 S and CA-120 W:
- This is the most direct route, taking around 5.5 to 6 hours of driving. The route takes you through beautiful landscapes, including the Eastern Sierra and Yosemite National Park (Tioga Pass, if it’s open).
- Via I-580 E and US-395 S:
- This alternative route is slightly longer, around 310 miles, and also takes about 5.5 to 6 hours. It bypasses Yosemite but is a good option during winter when Tioga Pass is closed.
Always check for road conditions and closures, especially if you’re traveling in winter, as some mountain passes can be closed due to snow.
