Santa Rosa, California is approximately 15 miles (24 kilometers) from the Pacific Ocean coastline as the crow flies.
Coastal roads (CA-1, River Rd, Bodega Hwy) are scenic but winding—allow 35-50 minutes from downtown Santa Rosa. Traffic peaks summer weekends.
Santa Rosa sits in the Santa Rosa Plain, east of the Coast Range. The Mayacamas Mountains (east) and coastal hills (west) frame the valley. The Russian River flows westward, reaching the Pacific at Jenner—accessible via kayak from Healdsburg (15 mi north of Santa Rosa).
