Traveling to San Mateo by RV

US-101 provides the main motorhome access route through San Mateo, with multiple exits serving the city. Highway 92 runs east-west through town, connecting the coast to the inland areas, though some sections can get congested during rush hours.

Overnight parking options are extremely limited in this urban area. Walmart locations here typically don't allow overnight motorhome parking, and street parking with an motorhome is prohibited in most residential areas.

Bridge clearances on major routes are adequate for most RVs, but be aware that some local streets have low-hanging power lines. The Peninsula's narrow streets in older neighborhoods aren't designed for motorhome traffic, so stick to main arterials when possible.
