Half Moon Bay to Guerneville: Coastal Redwoods & Wine Country Road Trip

Half Moon Bay sits on a coastal terrace that used to be part of a vast Spanish land grant, Rancho Corral de Tierra.

The journey takes 2.5 to 3.5 hours without stops, but you will want to pause at the many pullouts and state parks along the way.

• Pet-friendly: Almost all state parks allow leashed dogs on paved trails. Armstrong Redwoods welcomes dogs on the main path.
• Fatigue management: Alternate drivers every 45 minutes or use the audio guide from Wayro to stay engaged. Caffeine stops at Café del Soul in Mill Valley or Coast Kitchen in Bodega Bay.
