St. George to Weaverville: Epic Desert to Mountain Drive

This 680-mile journey crosses four major climate zones and two time zones, but its most surprising feature is the 45-minute time gain eastbound: you lose an hour at the Nevada border, then regain it entering California, making westward travel feel longer. The route uses I-15 north from St. George, then US-50 west, and finally CA-299 west into Weaverville.

The estimated driving time is 10 hours without stops, but plan for 12-14 hours to enjoy attractions.

The primary highways are I-15, US-50, US-93, I-80, and CA-299. Download offline maps because cell service is spotty in central Nevada. Fuel stations are sparse between Ely and Battle Mountain, so fill up at major towns.

• Gas stations: Frequent along I-15 and I-80, but only every 50-70 miles on US-50. Keep tank at least half full when crossing Nevada.
• Road conditions: High desert roads are well-paved but watch for wildlife at dawn/dusk. CA-299 is winding and two-lane; allow extra time.
• Unique stops: The Shoshone Dam at US-50, the Hickison Petroglyphs, and the Black Rock Desert playa near Gerlach.
