Hotels in San Mateo County, CA, United States

San Mateo County sits just south of San Francisco along the Pacific Ocean, with a mild Mediterranean climate where summer highs average 70°F (21°C) and winter lows rarely dip below 45°F (7°C). Famous for its redwood forests and a 55-mile stretch of rugged coastline, you can hike among ancient trees at Purisima Creek Redwoods Preserve during the drier summer months, then in winter watch migrating gray whales from the cliffs at Pigeon Point. The county's tech-heavy southern half near Palo Alto offers bike trails along San Francisco Bay, while the northern coast near Half Moon Bay provides world-class surfing, with the best swells arriving from November to March.
