Peninsula (Bay Area)

The Peninsula (or San Francisco Peninsula) region of the San Francisco Bay Area lies immediately south of the City and County of San Francisco—reaching from its famous neighbor to the north into the high-tech region of Silicon Valley. For purposes of this travel guide, the Peninsula is synonymous with San Mateo County. While many of the Peninsula's residents work and play to the north or south, the Peninsula has its attractions, including some beautiful wilderness areas. The Peninsula has two coasts—one on the San Francisco Bay, the other on the Pacific Ocean—but few major cities or ports. The Santa Cruz Mountains divide the region in half north-south, with a large wilderness area that's great for hiking and mountain biking. == Cities == 1 Belmont 2 Brisbane 3 Burlingame 4 Colma 5 Daly City 6MISSING WIKILINK El Granada 7 Foster City 8 Half Moon Bay 9 Hillsborough 10 Menlo Park 11 Millbrae 12 Moss Beach 13 Pacifica 14 Pescadero 15 Portola Valley 16 Redwood City 17 San Bruno 18 San Carlos 19 San Mateo 20 South San Francisco 21 Woodside == Get in == === By plane === The Bay Area has three major commercial airports: The San Francisco International Airport (SFO IATA) is on the Peninsula near Millbrae and San Bruno. The Oakland San Francisco Bay Airport (OAK IATA) is across the bay near Alameda and southern Oakland. The San Jose International Airport (SJC IATA) is at the bay's southern end between Santa Clara and northern San Jose. All three airports are served by public transportation. The regional metro-rail service BART runs directly to SFO and connects to the commuter rail line Caltrain, as does the San Mateo County bus service SamTrans. The East Bay bus service AC Transit and a connecting bus to BART, AirBART, run to OAK. Santa Clara County's Valley Transportation Authority runs a bus (Line 10) connecting SJC with Caltrain and that county's light rail and bus system. === By car === Motorists can reach the Peninsula from OAK by crossing the bay on the Bay Bridge (Interstate 80, to the north), the San Mateo-Hayward Bridge (Highway 92, to the south), or the Dumbarton Bridge (Highway 84, farther to the south). These are all toll bridges, and most of them cost $7 as of 2022. From SJC, drivers can take Highway 87 to US-101 northward, although avoiding 101's rush-hour traffic is often recommended. (For longer trips northward, try the scenic, parallel Interstate 280.) == Get around == === By train === ==== Caltrain ==== This commuter railroad runs up and down the Peninsula between San Francisco and San Jose, stopping at most major towns and serving San Jose International Airport (via a short transit bus connection at Santa Clara station). Service is fully electric north of San Jose as of September 2024, but service from San Jose to Gilroy is still provided by diesel trains which require a transfer. Caltrain runs 7 days a week until about 1 AM (10 PM on Sundays). If you miss the last Caltrain, local bus service is available all night. ==== BART ==== BART serves a small portion of the Peninsula, with some trains terminating at either San Francisco Airport or Millbrae. Caltrain and BART connect at Millbrae. === By bus === ==== Samtrans ==== The San Mateo County Transit District runs extensive bus service throughout San Mateo county, plus overlaps in Palo Alto and San Francisco. Some bus routes run all night. Normal bus fare for local routes and routes to San Francisco is $2.25; fares on SamTrans routes from San San Francisco are $4.00; and Clipper card users get an approximate 10% discount ($2.05 and $3.60 respectively). Useful bus routes include: ECR - Palo Alto Caltrain to Daly City BART, along El Camino Real. Stops at Millbrae 397 - Late night service between San Francisco and Palo Alto Caltrain. Stops at most Caltrain stations - useful for when Caltrain has stopped running. 292 - Downtown San Francisco to San Francisco Airport ==== VTA ==== The San Jose VTA runs buses throughout Santa Clara County, starting in Palo Alto. Normal bus fare is $2.00, express is $4.00, and Clipper is accepted. Routes that serve the Peninsula include: 22 - Palo Alto Caltrain to Downtown San Jose, along El Camino. 522 - Limited stop version of route 22 (still $2) === By car === The two main highways running down the peninsula are U.S. 101 and I-280. If you are driving from San Francisco to Palo Alto or San Jose, take I-280. It is a beautiful drive, free of advertising, well above the wilderness area. If you must drive on 101, avoid rush hour - it will be slow in both directions. The drive along the coast on State Route 1 (the Cabrillo Highway) is a beautiful, yet slow drive. === By bicycle === Many streets throughout the Peninsula have designated bike lanes, helping make cycling on the peninsula safer and easier. Key north-south bike routes include Alameda de las Pulgas, Middlefield Avenue, and Cañada Road. == See == The Peninsula has much to offer visitors. From a tourist's perspective, the most important tourist attractions along the Peninsula are the coastal drive along California State Route 1, Stanford University near Palo Alto, and Filoli, a historic country house in Woodside. In addition to Filoli, other historic sites include the San Mateo County History Museum in the historic county courthouse in Redwood City and the San Francisco Bay Discovery Site on Sweeney Ridge in the Golden Gate National Recreation Area, just west of San Bruno. For visitors interested in Silicon Valley and the tech industry, the most important tech company headquarters on the Peninsula include YouTube in San Bruno, Sony Interactive Entertainment and Roblox in San Mateo, and Meta Platforms and Instagram in Menlo Park. Oracle Corporation's former headquarters in Redwood Shores is also visually striking. Sand Hill Road in Menlo Park is famous for some of the most expensive commercial real estate on Earth. == Do == === Hiking === About 30% of the Peninsula is nature preserve, parkland, or otherwise undeveloped. There are many opportunities for hiking and mountain biking, all a short drive away. The transition from the crowded town along the eastern coast to empty wilderness is a rapid one! Most parks are managed by the Mid-Peninsula Open Space District, while some are part of local towns or counties. Almost every park permits mountain biking, and most allow horseback riding. Some excellent destinations for hiking include: 1 Monte Bello Open Space Preserve. Features open rolling grasslands and deep, cool river valleys. The views from atop Black Mountain can be excellent. Free. 2 Purisima Creek Redwoods. A densely forested park, with large redwoods. Free. 3 Russian Ridge Open Space Preserve. Sweeping views of the Pacific Ocean and Silicon Valley. Excellent in late winter and early spring when the wildflowers are in full bloom. Great place to watch the sunset. Free. 4 Sam McDonald Park. This park combines dense redwood groves adjacent to wide-open grasslands. A good choice if you can't make it to Muir Woods. $5.00. San Mateo County Parks. == Sleep == There are a few places to camp, mostly in California state parks. 1 Butano State Park. Just north of Santa Cruz, Butano is a nice park among giant old growth and second growth redwood trees. Close to Highway 1, this spot is an ideal location for travelers plying the San Francisco to Monterrey route. Not recommended for large RVs and trailers over 24 ft (7.3 m). 2 Portola Redwoods State Park. Long, winding, one-lane mountain roads keep most people away from this park. Their loss can be your gain. Some of the biggest trees in the Santa Cruz Mountains can be found in this park in the Peters Creek area. This park is nearly always empty. Not recommended for vehicles longer than 21 ft (6.4 m). == Stay healthy == Be careful to check for ticks after hiking in fields in the Bay Area. There is a high rate of Lyme disease transmission in the Bay Area. If a bulls' eye rash develops at the tick bite site, immediately seek medical help and treatment with antibiotics. == Go next == San Francisco East Bay South Bay - The Peninsula's southern neighbor is home to Silicon Valley, headquarters to hundreds of tech companies including giants like Apple, Intel and Hewlett Packard. Visitors will appreciate the massive array of restaurants, museums, and cultural opportunities offered by the huge city of San Jose, while at the other end of the spectrum the tiny town of Gilroy is famous for garlic, with its annual festival attracting over 100,000 garlic lovers. Santa Cruz County - Located south of the Peninsula, the second-smallest county in the state is home to the quirky town of Santa Cruz and a rugged coast that is equally popular with surfers and elephant seals. The Santa Cruz mountains are the abode of redwoods and bright yellow banana slugs, both of which can be easily seen on the many hiking trails. Other portions of the county are known for agriculture, with farm stands dotting the roads.
