Last updated: October 20, 2026. Halloween falls on a Saturday this year, so the final ten days of October are packed. Dates, prices and availability can change, so confirm with each organizer before you go.
The Quick Answer: What Are the Best Halloween Events in Pleasanton This Year?
The best Halloween events in Pleasanton, California in 2026 are Pirates of Emerson (a professional walk-through haunt at the Alameda County Fairgrounds, running select nights through November 1), Pumpkins After Dark (a new nighttime trail of more than 10,000 hand-carved pumpkins, also at the Fairgrounds), the Downtown Pleasanton Halloween Brew Crawl (Saturday, October 24, 5–8 PM), the Pleasanton Rotary Halloween Spirit Run (Sunday, October 25), and the Museum on Main Ghost Walk, a guided tour of downtown’s most haunted buildings. Families should also look at Boo Bash, the free trick-or-treat morning held each October in Downtown Pleasanton, which took place on October 17 this year and is worth putting on next year’s calendar.
If you only have one night, pick based on who is coming along. Want to be properly scared? Pirates of Emerson. Want something glowing and photogenic for the whole family? Pumpkins After Dark. Want a night out with friends in costume? The Zom-Brew Crawl. Want to start your Sunday with a race and a medal shaped like a pumpkin? The Spirit Run.
This guide covers each event in detail, plus nearby Tri-Valley celebrations, pumpkin patches, sample itineraries, practical tips, and a full FAQ. Everything here is about Pleasanton, California (Alameda County, in the Tri-Valley).
1. Pirates of Emerson: Pleasanton’s Legendary Haunted Attraction
If Pleasanton has a Halloween headliner, this is it. Pirates of Emerson is in its 36th season and is widely regarded as one of the largest professional haunts in the Bay Area. It began in a Fremont front yard on Emerson Street, spent time in a leased field, and has called the Alameda County Fairgrounds home since 2010.
What to expect: Four walk-through haunted houses set across several acres, with scare actors, elaborate sets, midway-style games, and live bands rotating through the calendar. New this year, the midway games are included with every ticket tier, which makes the price easier to compare against other haunts.
When: Select nights from October 2 through November 1, 2026. It is not open every night, so check the calendar before you drive over.
Where: Alameda County Fairgrounds, Gate 8, at the corner of Bernal Avenue and Valley Avenue. Parking at the Fairgrounds is paid, and there are more than 10,000 spaces, so you will find a spot even on a busy Saturday.
Tickets: Sold online only, with no tickets at the door. General admission starts around $38, and higher tiers add shorter lines. Tickets are entry-time based, so arrive a little early, and expect the Friday and Saturday slots closest to Halloween to sell out first.
Good to know: This is a genuinely intense attraction with strobe lighting and heavy jump scares. Past seasons have not recommended it for young children, and minors have needed an accompanying adult, so read the current age policy on the official site before buying tickets for a group that includes kids. The attractions are ADA accessible.
Pro tip: Weeknight time slots are usually calmer, and a Thursday or Sunday visit can mean noticeably shorter waits than a Saturday on Halloween weekend.
2. Pumpkins After Dark: A Glowing Walk Through 10,000+ Carved Pumpkins
New to Pleasanton in 2026, Pumpkins After Dark turns the Alameda County Fairgrounds into a lantern-lit walking trail. The experience features more than 10,000 hand-carved pumpkins arranged into illuminated scenes, along with live pumpkin-carving demonstrations, themed photo spots, seasonal treats, and roaming performers.
Why it stands out: It is the gentlest big-ticket Halloween option in town. There is nothing that jumps out at you, which makes it a great fit for toddlers, grandparents, and anyone who wants Halloween atmosphere without the screaming. It also photographs beautifully, so bring a phone with a good low-light camera.
When: Running evenings from October 2 through October 31. The final stretch (October 29, 30 and 31) has sessions starting at 6:30 PM, and Halloween night itself is available, which is a rare option for families who want to be out after trick-or-treating.
Where: Alameda County Fairgrounds, 4501 Pleasanton Avenue.
Tips: Buy timed tickets ahead of time, dress in layers (October evenings in the Tri-Valley cool off quickly), wear comfortable shoes for the full walk, and plan about an hour to an hour and a half. If you are doing both Pumpkins After Dark and Pirates of Emerson on the same night, they share the same Fairgrounds, which makes a double feature genuinely easy: the family trail first, then the haunts for the teens and adults.
3. Downtown Pleasanton Halloween Brew Crawl
On Saturday, October 24 from 5 to 8 PM, Main Street becomes the setting for one of the Tri-Valley’s most popular adult Halloween nights. Presented by the Pleasanton Downtown Association, the Halloween Brew Crawl sends costumed guests through downtown bars, restaurants, and shops to sample more than 20 brews from local breweries.
What is included: Ticket packages have featured tastings, select food bites, a commemorative glass, a wristband and an event map. Live music and a costume-friendly crowd keep the energy up, and yes, there are zombies strolling the route alongside you.
Check-in: Museum on Main, 603 Main Street.
Tickets: Sold through Eventbrite and available until the event date. This is an adults-only evening, so leave the kids with a sitter and bring a valid ID.
Why locals love it: The crawl format is the point. Instead of one venue, you spend the evening walking between tasting stops and discovering shops and restaurants you might otherwise pass by. It is also one of the easiest ways to get to know Downtown Pleasanton if you are new to the area.
Pro tips:
Eat something substantial before you start, even with food bites on the route.
Use a rideshare or designate a driver, and consider parking once and walking.
Wear a costume you can walk in for three hours. Elaborate wings and giant props get old fast on a crowded sidewalk.
Start at check-in early so you can sample every stop on the map without rushing.
4. Pleasanton Rotary Halloween Spirit Run
The morning after the crawl, the town gets a very different Halloween event. The Rotary Club of Pleasanton hosts the 33rd annual Halloween Spirit Run on Sunday, October 25, 2026, and it is one of the most fun-forward races in the Tri-Valley.
The lineup: A 5K and a 10K run or walk begin at 8:30 AM, with timed results and awards for overall winners and age groups. Kids ages 12 and under can join the Kids Challenge, which includes a quarter-mile run and a 100-yard dash starting at 10:00 AM.
What makes it special: Costumes are encouraged, finisher medals are Halloween-themed, and the event is both dog and stroller friendly. There is a post-race raffle, an expo area, refreshments, and music. Race entries include a technical or cotton-style shirt choice, depending on the registration option.
Pricing and registration: Registration prices rise after October 24 at 11:59 PM, so sign up before then. Packet pickup is Saturday, October 24, from 10:30 AM to 2:30 PM at Fleet Feet Pleasanton, 234 Main Street.
Why it matters: All donations and sponsorship dollars go back into the community, supporting scholarships for local students and Pleasanton-area nonprofits. If you want a Halloween activity that feels good in more than one way, this is the one.
5. Museum on Main Ghost Walk
Pleasanton’s older buildings have stories, and the Museum on Main shares them every October. The Ghost Walk is a roughly two-hour, family-friendly guided walking tour along Main Street. Costumed volunteers and young performers portray historical figures tied to downtown’s haunted locations, while a guide with electromagnetic field detection equipment keeps the mood spooky and the history real.
How it works: Tours leave the museum at 603 Main Street every 30 minutes between 6 PM and 8 PM on the Ghost Walk nights. Arrive at least ten minutes before your time slot to check in. The walk happens rain or shine, so dress for the weather.
Tickets: Historically, tickets have been in the range of $20–$25 and often sell out well before Halloween. Check the Museum on Main website or call (925) 462-2766 to see whether any 2026 time slots are still available. Pets other than service animals are not allowed on the tour.
Why go: It is the easiest way to learn something about Pleasanton while getting a few good (and gentle) scares. The event is also a fundraiser for the museum’s education programs, and it has been a local tradition for well over fifteen years.
6. Boo Bash: The Free Family Morning to Plan For Next Year
Downtown Pleasanton’s Boo Bash is held on Saturday, October 17 this year, and it is the gold standard for young kids who want to trick-or-treat in daylight. Families start at Museum on Main, follow clues to participating downtown businesses, collect candy, and enjoy free activities and a costume contest. Admission is free, and it runs mid-morning to early afternoon.
7. Trick-or-Treating on Halloween Night in Pleasanton
Halloween is Saturday, October 31, 2026, and Pleasanton’s traditional neighborhood trick-or-treating still happens the old-fashioned way: one street at a time, mostly between roughly 5:30 and 8:30 PM. There is no single official route, but a few things make a night go well:
Look for porch lights. A lit porch light is the universal “we have candy” signal. Skip dark houses.
Choose walkable blocks. Neighborhoods with sidewalks, gentle slopes and homes close together mean more candy per minute and fewer car rides.
Go early with little kids. The best time for toddlers and preschoolers is just before dusk, when it is still light.
Light up. Glow sticks, reflective tape and flashlights help drivers see children, especially on streets without sidewalks.
Adults need a plan too. Because Halloween falls on a Saturday, expect heavier foot traffic and more cars than usual.
A fun alternative if your own street is quiet: spend the early evening trick-or-treating, then head to Pumpkins After Dark, which has Halloween night sessions.
Nearby Halloween Events Worth the Short Drive
Pleasanton sits in the middle of the Tri-Valley, so you can easily build a weekend around what is happening in the neighboring cities.

Pumpkin Patches Near Pleasanton
Not every Halloween tradition needs a ticket booth. If your goal is a carving pumpkin, a hayride and a few family photos, these nearby patches have been reliable crowd-pleasers:
Joan’s Farm & Pumpkin Patch (Livermore): Open Tuesdays through Sundays in October, with a corn maze, farm animals, and inflatables. Hours are typically 10 AM to 6 PM, with activities closing a bit earlier.
Moore Pumpkin Patch (San Ramon): A long-time local favorite with jump houses and free admission and parking in past seasons. Confirm this year’s hours before you go.
Carving tip: wait until a day or two before Halloween to carve so your jack-o’-lantern stays fresh, and use battery-powered tea lights if you want to keep it safe for porches and little hands. Click here to read a full list of local pumpkin patches.

Practical Tips for Enjoying Pleasanton’s Halloween Season
Buy tickets in advance. Pirates of Emerson sells online only, Pumpkins After Dark uses timed entry, the Zom-Brew Crawl has a ticket cutoff, and the Ghost Walk tends to sell out. If it is on your list, buy it this week.
Plan your parking. Downtown Pleasanton events are easiest if you park once and walk. For events at the Alameda County Fairgrounds, follow the signs for Gate 8 and budget a few extra minutes for entry on Friday and Saturday nights.
Check the weather. October in Pleasanton can swing from warm afternoons to chilly evenings. Layers are a good idea, and some events (like the Ghost Walk) go on in the rain.
Costume comfort wins. For long walks or runs, choose a costume you can wear for hours. Comfortable shoes beat perfect accessories.
Be kind to local businesses. Downtown shops and restaurants rely on seasonal foot traffic. Pick up a treat, a coffee, or a meal while you are out.
Safety first. Keep kids within sight, use reflective or light-up accessories, and give yourself a safe ride home if you are enjoying a tasting event.
Why Pleasanton Does Halloween So Well
Part of the appeal is the setting. Downtown Pleasanton has a walkable, small-town Main Street feel, with historic buildings, local breweries, independent shops and community organizations that really show up for seasonal events. Around it, the Alameda County Fairgrounds adds the kind of large-scale venue that makes bigger productions possible, and the surrounding Tri-Valley (Livermore, Dublin, San Ramon and Danville) means there is almost always another celebration just a few minutes away.
If you are visiting for the first time, you might notice something else: how many of these events are run by community groups. The Pleasanton Downtown Association, the Rotary Club and the Museum on Main all put on programs that give back to local students, nonprofits and education. It is a good snapshot of what living here can feel like year-round, with traditions that bring neighbors together for every season.
If you are thinking about making the Tri-Valley your home, a few October weekends in Pleasanton are a good way to test drive the lifestyle. Spend a morning on Main Street, walk a few neighborhoods, and see how the town feels when it is dressed up for a celebration. Your next chapter starts here, and I am always happy to talk through neighborhoods, schools and what to expect from the market.
