Start with a visit to the Huntington Library, Art Museum, and Botanical Gardens, where parking areas accommodate visitor vehicles and offer easy access from local streets. Lacy Park provides a short, scenic drive and a pleasant place to stretch legs after time on the road. A Class C fits well on these local roads and into visitor lots at major sites. For longer drives and connections beyond town, Interstate 210 provides a wide, well-maintained route that is commonly used by larger RVs and offers straightforward exits for fuel and services. Combining short local journeys with this major highway makes day trips comfortable and practical from San Marino.
