Drive from Napa Valley to Las Vegas

Question

On 5th of July we will drive to Las Vegas, leaving the Napa Valley area (maybe Sonoma Coast area). We want to take the scenic route, so crossing the west side of Yosemite etc, and not driving only on highways (the I5). From Sacaramento we can opt for the 395 or 95, it is about the same amount of travel time. Assuming the 395 would be the most scenic ? And wanting to do an overnight stay in about the middle of the route; so around the Mammoth Lakes area.

Any thoughts on the above, sounds about right ? Or will it be extremely crowdy in the 4th of July weekend on these roads ? And the I5 will not be so scenic, right ?

Any thoughts/suggestions on a nice, special, authentic overnight stay in that area ? We do like luxury, but can enjoy something cozy and authentic (and we have Vegas afterwards ;-) !).

Answer

Your plan to drive from Napa Valley to Las Vegas while taking a scenic route is excellent if you want to avoid the monotony of the I-5 and enjoy some of California’s best landscapes. The I-5 is efficient for travel but very utilitarian—mostly flat, agricultural scenery, and lacks the mountain vistas, forests, and lakes you’ll see on the alternative routes.

Here’s a breakdown and recommendations for your trip:

Scenic Route via Yosemite West Side and Highway 395: From Napa/Sonoma, head toward Sacramento and then east via Highway 49 or 120 toward the Sierra Nevada. If you want to cross the west side of Yosemite, take CA-120 (Big Oak Flat Road) or CA-140 (Merced River Canyon) depending on which entrances are open. This will give you forested mountains, rivers, and small towns.
Highway 395 Alternative: After exiting Yosemite’s eastern side, taking US-395 south toward Mammoth Lakes is highly scenic. You’ll pass Mono Lake, the Eastern Sierra mountains, and countless alpine vistas. Compared to NV-95 or I-5, 395 offers mountains, lakes, and high desert views, making it ideal for a scenic drive.
Traffic Considerations: The 4th of July weekend is peak summer travel, so expect moderate to heavy traffic, especially near Yosemite entrances, Mono Lake, and Mammoth Lakes. Early morning departures and leaving towns before mid-morning can help avoid major congestion.
Overnight Stay near Mammoth Lakes: Mammoth Lakes and the surrounding Eastern Sierra towns have several options for memorable stays:

The Westin Monache Resort, Mammoth Lakes: Luxury, comfortable, and close to the lake and town amenities. Great for families and offers easy access to scenic drives.
Convict Lake Resort: Cozy, authentic, and more rustic. Situated on the lake with spectacular mountain views, perfect for a quieter, scenic experience.
Mammoth Mountain Lodge: Central location with lodge-style rooms, providing both comfort and access to nearby trails or mountain vistas.
Custom Cabin Rentals: Airbnb or local vacation rentals in Mammoth Lakes often offer secluded, authentic cabins with luxury touches—great if you want privacy and the mountain experience.

Additional tips:

Bring plenty of water, snacks, and a filled gas tank, as services can be sparse along some 395 stretches.
Check for any Yosemite road closures or detours, especially Tioga Pass (CA-120), as it may still have snow patches or late-season maintenance in early July.
Consider timing your drive so that you reach Mammoth Lakes in the late afternoon for sunset views of the lakes and mountains.

In summary, the 395 route is definitely the more scenic and memorable option compared to I-5 or NV-95, and an overnight stay in Mammoth Lakes or nearby alpine resorts provides both comfort and a quintessential Eastern Sierra experience before heading onward to Las Vegas.
