Which flavor of Halloween do you prefer—the holiday that includes candy and carved pumpkins, or the kind that makes you want to jump out of your skin? California has a nice blend of both, thanks to a deep inventory of local festivals, fun-loving zoos and aquariums, and some historic sites with legitimately creepy backstories.
Certainly, California theme parks celebrate Halloween with lots of flair—and they start early, often kicking off their parties in early September. But that’s only the beginning: Here are many more Halloween season events worth planning a trip around—and happily, some of them last well beyond Oct. 31.
Sept. 13–Oct. 31: Unhinged at Winchester Mystery House, San Jose
Autumn is prime time for this 160-room mansion in San Jose, which has a bizarre origin story: It was built by an eccentric heiress who was trying to ward off ghosts. This year’s event, “Unhinged Hotel,” unravels within this frame story: a group of friends, stranded due to car trouble, stumble upon an old hotel with plenty of vacancy. (Spoiler alert: It doesn’t lead to a night of undisturbed sleep.) After the experience, peruse the house’s new Halloween Museum and catch your breath outside with snacks and drinks at Café 13.
Sept. 29–Oct. 31: Heartstoppers Haunted House, Rancho Cordova
Scream your way through four scare zones—with themes like the dark hospital on the hill (“The Ward”) and a raising of the dead (“Redemption!”)—on select nights in this decked-out, three-story building in Rancho Cordova. To release the tension afterward, enjoy the outdoor offerings of carnival games, live performances, and character photo ops.
Oct. 4–27: HalGLOWeen at the San Diego Zoo, San Diego
The world-famous zoo in San Diego stays open late on select nights so partiers can enjoy music, bubbles, acrobats, and more—all aglow under spooky black lights. Runs on Fridays, Saturdays, and Sundays during October. Bonus: Since it’s Kids Free San Diego during October, kids 11 and under get into the zoo for free.
Oct. 1–29: Boo at the Zoo at the Oakland Zoo, Oakland
Explore Oakland’s zoo and enjoy activities such as the hay-bale maze and a scavenger hunt, then collect as your prize: an Oakland-made OCHO candy bar. Come dressed for the holiday—just no inflatable costumes, which reportedly scare the animals—and enter the themed costume contest by tagging the Oakland Zoo on social media. Contest winners will receive tickets to Glowfari, the zoo’s holiday nighttime event that runs Nov. 10–Jan. 28. All admissions are arranged online and event capacity is limited, so book your tickets ahead of time.
Oct. 5–Nov. 30: Pumpkin Patch Express, West Sacramento
Take this seasonal ride on Yolo County’s River Fox Train. The weekend excursion on a vintage train lasts about two hours and includes time at a private park, your own pumpkin, trick-or-treating, and sack races.
Oct. 2–30: Skunk Train's Pumpkin Express, Mendocino County
Combine a train ride with a pumpkin patch on this excursion on Mendocino County’s Skunk Train, which departs from Willits. Enjoy seasonal treats during the ride on the 1885 train, then explore both a redwood forest and pumpkin patch, where you can pick out your own gourd and take pictures before getting back on the train. Runs on select dates, mostly on weekends and Mondays.
Oct. 1–31: Casa de Pumpkin Patch, Hollister
The fruit stand, gourmet shop, and RV resort Casa de Fruta pulls out the stops for the Halloween season with a field of pumpkins as well as a kiddie train, a carousel, and gold-panning. On weekdays, the San Benito County attraction also offers educational activities for groups as small as 10: Learn about Native American culture through music-making sessions and by creating beaded bracelets (though October).
Oct. 4–25: Boardwalk Fright Flicks, Santa Cruz
Watch scary movies and enjoy a cocktail at this 21-and-up event that happens every Wednesday during the Halloween season at Santa Cruz’s old-school Beach Boardwalk. The lineup includes Us, Dawn of the Dead, Killer Klowns from Outer Space, and Trick ‘r Treat.
Oct. 5–26: Headless Horseman Wagon Ride, Temecula
Many people experience Temecula Valley from a hot-air balloon, but this seasonal event offers a different perspective: You’ll clip-clop along on an old-fashioned wagon ride, driven by Temecula Carriage Company through “Wine Country Hollow.” The family ride explores a few not-too-spooky spots while everyone keeps an eye out for the legendary Headless Horseman. Friday and Saturday nights only.
Check out more of Temecula Valley’s Halloween-season fun, such as haunted walking tours of Old Town, stomping grapes in costume at Wilson Creek Winery, and the Carnevil Ball at Europa Village.
Oct. 4–30: Carved at Descanso Gardens, Pasadena
Pasadena may showcase rose-petal-based parade floats in January, but the Los Angeles County area excels at carved pumpkins too—as in, hundreds of them—along a one-mile walk in the park’s Camellia Forest. You can also watch demos to learn how to better carve your own masterpiece at home.
Oct. 19–20: Half Moon Bay Art & Pumpkin Festival, Half Moon Bay
The town of Half Moon Bay, located on the San Francisco Peninsula, is surrounded by pumpkin patches and is the self-proclaimed “World Pumpkin Capital.” This beloved festival includes enormous pumpkins, sculpted pumpkins, a Great Pumpkin Parade, and pie-eating contests, along with seasonal craft beer, pumpkin-infused ales, and cocktails.
Oct. 18–27: Boo at the Zoo at the Santa Barbara Zoo, Santa Barbara
Come in costume to Santa Barbara’s zoo on weekend evenings (Friday through Sunday) for trick or treating, a train ride, wacky-mad scientist experiments, and encounters with creepy-crawly zoo residents.

Dress up to explore the zoo located within Los Angeles’s Griffith Park. Weekend activities include special shows, a maze, education stations, and pumpkin feedings for the zoo residents.
Oct. 21–22, 28–29 Boo at the Zoo at San Francisco Zoo & Gardens, San Francisco
Celebrate the season at the San Francisco zoo during the last two weekends of the month.

While you’re there, enjoy the ZootoberFest celebration with a giant hay maze and German-inspired food, beer, and entertainment.
Oct. 26: Dia de Los Muertos Festival, Los Angeles
Downtown Los Angeles’s Day of the Dead remembrance for departed ancestors—rooted in Mayan, pre-Colombian, and Aztec traditions—is celebrated on historic Olvera Street. Come each evening for the processions, featuring blessings, dances, treats, and face-painting. Not far away, the Hollywood Forever Cemetery will do its own one-day festival on Oct. 28.
Oct. 29: Zombie Bike Parade Festival, Davis
The Yolo County town of Davis is a bicycle-friendly town, even for zombies. This free event welcomes you to join a 12-mile bike parade of zombies along the Davis Bike Loop, a Zombie Paintball competition, and a family-friendly pre-bike brew party hosted by Sudwerk Brewing Co. There’s also a “zombie mash afterparty” with music and BMX performers.
Oct. 27–31: Creepy Tour and a Halloween Pub Crawl, Siskiyou County
Siskiyou County’s modern history includes plenty of Gold Rush lore. Start in Yreka with the Miner Street Ghost Tour on Oct. 26, and the Spooky Halloween Evergreen Cemetery Walking Tour on Oct. 31.

Oct. 31: Halloween Carnaval, West Hollywood
The epic street party in West Hollywood returns this year for the first time since 2019: a join-the-fun parade of costumes and self-expression along Santa Monica Blvd., between North Doheny Dr. and La Cienega Blvd. The event is free, but given its reputation for risqué costumes, you might want to leave the little ones with a sitter.
Oct. 31: Halloween on the Wharf: Trick-or-Treat by the Bay, Monterey
Spend Halloween in Monterey County, which hosts a few different creative parties. Wear your Halloween best to the historic Old Fisherman’s Wharf, which features a costume contest, trick-or-treating, and a Halloween DJ.

This year, the town turns 108.
Nov. 2: Dia de los Muertos, Hornitos
Pay your respects to ancestors in the near-ghost town of Hornitos (population. 50) in Mariposa County, about 50 miles from Yosemite National Park. The town is known as the home of “bandit-hero” Joaquin Murrieta, whose spirit may still wander here, especially near the town’s hilltop cemetery. Start in the town plaza and follow the candlelight procession up a hill to the historic St. Catherine’s Church and cemetery.
Ongoing: San Francisco Ghost Tour, San Francisco
Take this walking tour from The Haunt that explores real scare zones in San Francisco’s Chinatown and Jackson Square—haunted sites associated with graves, crimes, and buried treasure. It’s not just stories, either: You’ll get to use special gear that helps detect possible paranormal activity.
