San Jose day trip

San Jose is the largest city in Northern California and the unofficial capital of Silicon Valley, yet many visitors to Palo Alto never make the 20-mile trip south. That is a shame. San Jose is easy to reach by Caltrain, quick to get around and has a handful of sights you will not find anywhere else, from the sprawling Winchester Mystery House to one of the last surviving historic Japantowns in the United States.

It is also a good bad-weather choice. Most of the highlights are indoors and the city is often a few degrees warmer and sunnier than the Peninsula. This guide covers how to get there, what to see downtown, the Winchester Mystery House, Japantown and Santana Row, plus a sample plan.

Getting there by Caltrain or car

By Caltrain

Southbound Caltrain trains run from Palo Alto station to San Jose Diridon, the city's main station, in roughly 20 to 35 minutes depending on the number of stops. Tap a Clipper card or a contactless bank card on the platform reader before you board and again at Diridon. Our getting around guide explains fares and the other Palo Alto stations.

Diridon station is undergoing construction in fall 2026, with platform and track assignments changing from October 19 through December. Follow the signs and monitors at the station and check caltrain.com for alerts before you travel.

From Diridon, downtown is about a mile east. You can walk along Santa Clara Street or San Fernando Street in about 20 minutes or ride VTA light rail. SAP Center, home of the San Jose Sharks, sits right beside the station.

By car

Driving takes 25 to 40 minutes via Highway 101 or Interstate 280 outside rush hour. A car is the easier choice if you want to combine downtown with the Winchester Mystery House and Santana Row, which sit about three miles west of the center. Downtown has plenty of public garages.

Downtown San Jose

San Jose was founded in 1777 as El Pueblo de San José de Guadalupe, the first civilian town in Spanish California. It also served as California's first state capital after statehood. Little from those early years survives, but the downtown core around Plaza de César Chávez is compact, green and easy to explore on foot.

The Tech Interactive

The Tech Interactive at 201 S. Market St. is a hands-on science and technology center that suits curious kids and adults alike. Expect labs and design challenges where you build, test and experiment, plus an IMAX dome theater that also hosts laser shows set to music. The traveling exhibition Body Worlds Decoded is on view into 2027. Check the museum's website for the daily schedule, since hours vary.

Around the plaza

• San Jose Museum of Art focuses on modern and contemporary art, with an emphasis on artists from the West Coast.
• Cathedral Basilica of St. Joseph is a domed 19th-century church facing the plaza.
• San Pedro Square, a few blocks north, is the main dining area, with a food hall and restaurants spilling onto the sidewalks.
• Children's Discovery Museum, south of the center, is a good stop with younger kids.

The Winchester Mystery House

The Winchester Mystery House at 525 S. Winchester Blvd. is San Jose's most famous attraction. Sarah Winchester, heiress to the Winchester Repeating Arms fortune, kept building and rebuilding her Victorian mansion for about 36 years, from 1886 until her death in 1922. The result is a maze of 160 rooms with staircases that lead into ceilings, doors that open onto walls and windows set into floors. Legends about why she built it have grown for more than a century and the guides enjoy sorting fact from fiction.

The main option is the guided Mansion Tour, which lasts about 65 minutes and passes through 110 rooms. Self-guided add-ons cover parts of the basement and attic. On select evenings, flashlight tours take you through the house after dark. In fall, Festival Fright Nights adds haunted mazes and live entertainment on the grounds, with separate ticketing. Book online, especially around Halloween. You can check Winchester Mystery House tickets alongside other San Jose attractions.

Japantown

San Jose's Japantown, just north of downtown, is one of only three historic Japantowns left in the United States, along with those in San Francisco and Los Angeles. It grew up in the late 1800s next to the city's old Chinatown, as Japanese immigrants arrived to work on the orchards and farms of the Santa Clara Valley.

• Jackson Street is the main street, lined with family businesses, restaurants and small shops. Shuei-do Manju Shop is known for traditional Japanese sweets, but its own website returned an error when we checked, so call ahead.
• The Japanese American Museum of San Jose covers more than a century of local history, including immigration, farming and the wartime incarceration of Japanese Americans.
• San Jose Buddhist Church Betsuin on Fifth Street was founded in 1902, according to the temple.
• Festivals include Obon every July, Nikkei Matsuri in spring and Aki Matsuri in fall. The Japantown farmers market is now seasonal, running Sundays from 8 a.m. to noon from May to October at 357 E. Taylor St. The 2026 season is over and the market reopens in May 2027.

VTA light rail stops at Japantown/Ayer station, so you can ride up from downtown. Our San Jose Japantown guide covers the museum, history and festivals in more detail.

Santana Row and Valley Fair

Santana Row is an outdoor shopping and dining district on Stevens Creek Boulevard in west San Jose, built to feel like a European main street. It has shops, restaurants, bars, a hotel and apartments above the storefronts and it is liveliest on weekend evenings. The large Westfield Valley Fair mall is right across the street. Both are about a mile from the Winchester Mystery House, so they make a natural pairing for an afternoon and dinner. Our Santana Row and Valley Fair guide has shopping and parking tips.

More to see

If you have extra time, the Rosicrucian Egyptian Museum in the Rose Garden neighborhood holds one of the largest collections of Egyptian artifacts in the western United States. Nearby, the San Jose Municipal Rose Garden is at its best from late spring into fall. For a slower neighborhood stroll, our Willow Glen guide covers Lincoln Avenue and how to get there. Silicon Valley fans can also drive past famous tech campuses on the way home. Our Silicon Valley history guide and our list of famous tech addresses explain what you are looking at.

A sample day

1. Take a mid-morning Caltrain from Palo Alto to Diridon.
2. Walk or ride light rail downtown and spend the late morning at The Tech Interactive.
3. Eat lunch around San Pedro Square.
4. Ride light rail to Japantown for an hour of wandering and the museum.
5. Take a rideshare to the Winchester Mystery House for an afternoon tour.
6. Walk to Santana Row for dinner, then take a rideshare back to Diridon for the train home.

With a car, reverse the order to avoid driving downtown at rush hour. Families can swap the Winchester tour for the Children's Discovery Museum. See our guide to Palo Alto with kids for more ideas closer to home.

Tours and staying over

Most visitors explore San Jose on their own, but a guided Silicon Valley tour is a good way to see the tech campuses in Mountain View, Cupertino and Santa Clara along with San Jose. You can browse Silicon Valley tours that include stops in the city. If you are attending an event at SAP Center or a conference downtown, staying in San Jose is often cheaper than Palo Alto on weekdays. You can compare San Jose hotels near Diridon or downtown.
