5 Weekend Events in Vancouver, WA & Portland Not to Miss (October 23–25, 2026)
This weekend (October 23–25, 2026), you can hit the free Clark County Trunk or Treat in Vancouver on Friday from 5 to 8 PM, sip wine at the 21+ Pumpkin Lane After Dark in Yacolt on Friday evening, see The Rocky Horror Picture Show live at the Kiggins Theatre on Saturday at 10 PM ($15), ride the Chelatchie Prairie Railroad’s Headless Horseman Halloween Special in Yacolt on Saturday or Sunday, or head to Portland on Sunday for the Oregon Mycological Society Fall Mushroom Show ($20, kids under 12 free).
It’s the last weekend before Halloween, and Clark County is not holding back. Friday night alone has two great options depending on whether your crew is wearing pajama-costumes and carrying candy buckets or wants a glass of wine by the fire. Saturday brings a midnight-ish movie classic downtown, the weekend has a spooky train ride in Yacolt, and Sunday there’s one very good reason to drive to Portland: mushrooms. Lots of them. Some of them glow.
Still need a costume or a carving pumpkin? My Halloween costume and pumpkin carving guide has local stores and patches still open through Halloween. If the forecast turns wet (it’s late October, so plan on it), my rainy day date night ideas in Vancouver, WA have you covered.
Here are five events worth knowing about this weekend in Vancouver, Yacolt, and Portland.
Clark County Trunk or Treat — Vancouver, WA
RV Inn Style Resorts hosts the 5th annual Clark County Trunk or Treat, one of the biggest family Halloween celebrations in the county. The convention center fills up with creatively decorated trunks and booths from local businesses and community organizations. Best part? It’s indoors, so the rain can do whatever it wants.
What to Expect
- Trunk-or-treating at decorated trunks and booths
- Bike giveaways
- Costume contests for kids and adults
- Local Clark County businesses and organizations to meet
💡 Pro Tip from a Local
Bring the biggest candy bucket you own, and don’t leave the adult costume contest to the kids. Consider this your dress rehearsal for Halloween night. Arrive close to 5 PM for the best selection before the crowds roll in.
Pumpkin Lane After Dark — Yacolt, WA
Pomeroy Farm’s scarecrow-lined Pumpkin Lane gets a grown-up makeover after sunset. Take an evening hayride down the lane, wander the pumpkin patch, grab BBQ from Mosscrowe BBQ, and settle in with a glass of wine and a freshly roasted s’more. Honestly, it’s one of the coziest date nights of the season.
What to Expect
- An evening hayride down Pumpkin Lane
- One beverage token and two s’mores kits included with your ticket
- Food from Mosscrowe BBQ, extra drinks, and pumpkins available to buy
- A 21+ crowd, so you can leave the kids with grandma
💡 Pro Tip from a Local
This is the last After Dark night of the season, so get tickets on Eventbrite before you go. Yacolt gets cold fast once the sun drops, so wear layers and real shoes (it’s a farm). Pomeroy recommends bringing cash, since there’s no ATM on site.
The Rocky Horror Picture Show at the Kiggins Theatre — Vancouver, WA
Vancouver’s own shadow cast, The Denton Delinquents, takes over the historic Kiggins Theatre. The movie plays on screen while the cast performs right in front of it, complete with costumes, makeup, props, and every iconic dance number. Yelling callback lines and joining the prop throws is half the fun, and the usherette hands out everything you need.
What to Expect
- A live shadow cast performing alongside the film
- Audience callbacks and prop throws (props provided)
- Come dressed however you like, whether you’re a longtime fan or a first-timer
- All ages allowed, but the movie is rated R and the pre-show gets a little wild
💡 Pro Tip from a Local
Make a night of it with dinner on Main Street before the 10 PM show. Parents, take the “parental discretion advised” note seriously. Can’t make it? The next show is November 28.
Chelatchie Prairie Railroad: Headless Horseman Halloween Special — Yacolt, WA
All aboard for a spooky (but not too spooky) ride through the North Clark County countryside. The Chelatchie Prairie Railroad’s resident Headless Horseman makes an appearance, and riders are welcome to come in costume. It’s a great daytime Halloween outing for families with little ones who aren’t ready for the after-dark scares.
What to Expect
- A vintage train ride departing from the Yacolt station
- A sighting of the elusive Headless Horseman
- Three departures each day, Saturday and Sunday
- Costumes encouraged for kids and grown-ups
💡 Pro Tip from a Local
Bring your camera for a family photo with the Headless Horseman. Make it a north county day trip with a stop at Moulton Falls, about 10 minutes away, and a pumpkin pickup at Pomeroy Farm’s Pumpkin Lane, which is open on weekends.
Oregon Mycological Society Fall Mushroom Show — Portland, OR
The Oregon Mycological Society’s Fall Mushroom Show is its biggest educational event of the year, packed with beautiful displays of wild Pacific Northwest mushrooms, all identified and labeled by experts. For 2026, the show is expanding into Cheatham Hall, adding more room to explore, and the Blacklight Room is back by popular demand.
What to Expect
- Wild mushroom displays from around the Pacific Northwest
- Mushroom experts to answer your ID questions
- The Mushroom Market and educational partners
- The returning Blacklight Room (yes, some fungi glow)
💡 Pro Tip from a Local
Snap photos of the mushrooms popping up in your yard or on your favorite trail and bring them with you. This is the place to finally find out what they are. Pair it with a walk through Washington Park, right next door, while the fall color is peaking.
