Bishop to St. Helena Road Trip Guide: Scenic California Drive

This route traces the eastern Sierra Nevada along US-395, crossing the Tioga Pass (CA-120) through Yosemite National Park, then descending into California’s Central Valley and finally the Napa Valley. The pass is typically open from late May to October, but snow closures can occur as early as November. The total driving distance is about 350 miles, taking roughly 6–7 hours without stops, but plan for a full day to enjoy the sights.

One quirky detail: the Tioga Pass is the highest highway pass in California at 9,945 feet, and its opening date varies widely; in 2023 it opened on May 19, while in 2019 it didn’t open until July 1. Always check current conditions at nps.gov/yose.

Road quality varies: US-395 is excellent, but Tioga Pass has no guardrails in some sections. Speed limits are 55 mph on open roads, 25 mph in curves. Winter tire requirements apply in snow. Cell service is spotty from Lee Vining to Crane Flat. Download offline maps beforehand.

• Fatigue Management: Take breaks every 2 hours. Recommended rest stops: June Lake Loop (scenic rest area), Yosemite's Olmsted Point (picnic tables), and the Oakdale rest area on CA-108 for a stretch.
• Family Suitability: Kids will love the Mono Lake tufa formations and Yosemite’s Tuolumne Grove of giant sequoias (short hike). The Napa Valley has balloon rides but are weather-dependent.
• Pet-Friendly: Pets allowed on paved trails in Yosemite but not on unpaved trails. Mono Lake's boardwalk is pet-friendly. Many Napa wineries require pets to stay in the car.
• Hidden Off-Route Spots: The ghost town of Bodie (near Bridgeport, detour of 13 miles) and the Rainbow Pool hot springs in Bridgeport (seasonal).

Things to do between Bishop, CA and St. Helena, CA include hiking, wine tasting, and ghost town exploring.

US-395 is a well-maintained four-lane highway, but the Tioga Pass section (CA-120) is two lanes with sharp curves. Fuel in Bishop is plentiful, but after leaving Bishop, the next gas station inside Yosemite is at Tuolumne Meadows (seasonal) or Crane Flat. Fill up before climbing the pass. The Central Valley along CA-99 and I-5 has frequent stations, and the Napa Valley has premium fuel options.

• Bishop: Last full-service town before Yosemite with Chevron, Shell, and ARCO.
• Lee Vining: 60 miles north of Bishop, has a Mobil station and diner.
• Yosemite (Tuolumne Meadows): Gas available only in summer; cash or card.
• Groveland/Big Oak Flat: Entering the Central Valley, there are Conoco and Chevron stations.
• St. Helena: Multiple stations but prices are higher due to Napa premium.
