Rather than a single “best” drive, Northern California travelers typically choose between two types of routes, depending on conditions.
Trans-Sierra Routes (Seasonal)
These routes cross directly over the Sierra Nevada and are known for dramatic scenery, high elevations, and limited access windows. When open, they offer a more immersive mountain experience but require flexibility and awareness of closures.
All-Season Routes (Year-Round)
When Sierra crossings are closed, travelers approach Mammoth Lakes by routing around the mountains and entering the Eastern Sierra from the north or south. These routes are longer but more reliable during winter weather.
What Kind of Experience Are You Looking For?
Your ideal route depends on what you value most:
- Scenery and alpine landscapes → seasonal Sierra crossings
- Reliability and winter access → all-season approaches
- Avoiding crowds → lesser-used seasonal routes when available
There’s no single right answer—only the right choice for your timing and priorities.
