Traveling to Arroyo Grande by RV

US-101 runs right through Arroyo Grande as your primary route. Take Exit 187 (Grand Avenue) for Old Town or Exit 182 (Lopez Drive) for the lake area dump station. CA-227 connects you northeast to San Luis Obispo in 15 minutes.

CA-1 hugs the coast three miles west. It's scenic but narrow in sections -- not ideal for larger rigs towing vehicles. Stick to 101 if you're over 35 feet.

Overnight parking isn't permitted at the RV waste disposal facility. Walmart on West Branch Street historically allowed overnight stays, but call ahead to verify current policy. Lopez Lake Recreation Area offers full hookup sites if you need more than a quick dump. Downtown streets are tight -- avoid Old Town with anything over 25 feet. Several Pismo Beach casinos welcome overnight RV parking if you're gambling.
