San Marino's compact streets and close proximity to the foothills make it a practical base for towable toy hauler travel. Access to I-210 and nearby Arroyo Seco Parkway provides straightforward routes to mountain trails and coastal highways, and several campgrounds within a short drive offer pull-through sites and hookups. Local parking at attractions and museum lots is generally easy for unhitching and setting up a camp kitchen, and many RV-friendly sites have level pads for safe setup. Unhitching gives you the freedom to take motorcycles or small off-road vehicles into the mountains for flexible day trips while leaving the rig secured at your site.
