Highlights reachable by road from San Marino include the Huntington Library and Botanical Gardens, Lacy Park, and the San Marino Historic District, each offering convenient parking and walkable grounds. For a scenic connector, Interstate 210 (the Foothill Freeway) provides a straightforward, RV-friendly route with wide lanes and easy on- and off-ramps to regional destinations. Travelers in a motorhome will find gentle grades and clear signage along the 210, which helps when navigating a larger vehicle. These routes make half-day drives and museum visits from San Marino simple to plan.
