San Francisco to Groveland Road Trip Guide

The route from San Francisco to Groveland follows Interstate 580 east to Interstate 205, then California State Route 99, and finally California State Route 120 east into the Sierra Nevada foothills. This 155-mile journey typically takes 2.5 to 3 hours without stops, but the real value lies in the detours. The Yosemite Valley Railroad once connected Groveland to the park, and remnants of that narrow-gauge line still dot the landscape near Don Pedro Reservoir.

The drive samples diverse ecosystems: from coastal fog to oak-studded ranchlands, then pine forests. It raises the question is it worth driving San Francisco, CA to Groveland, CA? Absolutely—the gateway to Yosemite’s western entrance is rich with history, river canyons, and small towns.
