Corn Mazes and Pumpkin Patches in Washington State: A Region by Region Guide

Somewhere in a field outside Snohomish, twelve acres of corn are cut into the exact shape of Washington State. You can walk from the Puget Sound coast across the Cascades and out toward the Idaho border, following more than 250 real roads and 400 towns and landmarks carved into the rows, on about four and a half miles of paths. That maze, at Swans Trail Farms, is the best single reason to go looking for corn mazes in Washington this fall. It is also probably not the closest one to you, which is the good news.

Here is the season in one line. The farms open between mid September and the first weekend of October, the sweet spot is late September through the middle of October, and almost everything shuts down on October 31 or November 1. Many of the best activities run on weekends only. What follows is a region by region guide to the best corn mazes and pumpkin patches in Washington, grouped by where you live, so a family anywhere in the state can find its patch close to home.

When to Visit Pumpkin Patches in Washington

The season runs about six weekends and it looks the same everywhere. Most farms open in the second half of September, a few wait until the first weekend of October, and the early weeks bring fresh fields and light crowds. Late September through the middle of October is the peak, with everything open and the best odds on weather. By late October the pumpkin selection thins out, but the Halloween events and night mazes take over. Almost everything closes on October 31 or November 1.

Two honest warnings. Many farms run their full activity lineup on weekends only, so a Tuesday visit might get you the patch but not the maze or the rides. And a sunny Saturday in October is the single busiest day of the season at every one of these places. If you dislike lines, go Sunday morning right at opening, with a thermos for the drive out, and you will have the maze half to yourself.

One more planning note, especially with young kids. Several of these farms run separate after dark attractions that are built to scare, not to charm: the Zombie Paintball and haunted house at Thomas Family Farm, the Haunted Woods at Maris, the night maze at Bob’s, the haunted maze at Union Gap, and the night maze at Bi-Zi. They run on set evenings, mostly late in the week, and the haunted ones sell separately from daytime admission. If you are bringing little ones, go during the day and leave the night ticket alone. If you have teenagers, the after dark farms are the whole point.

Snohomish County: The Patch Capital of Washington

One river valley north of Seattle holds the densest cluster of corn mazes and pumpkin patches in the state, most of them within a few miles of each other around the town of Snohomish, 30 to 45 minutes from the city. If you only drive to one region, drive to this one. Our Snohomish city guide covers the rest of the town, and our Northwest Washington region guide covers the small towns around it.

Swans Trail Farms (Snohomish). This is the one with the Washington State map. The farm cuts its twelve acre corn maze into the shape of the state, with more than 250 roads and 400 towns and landmarks carved into the corn, so you can walk from the coast to the Idaho line. It is the signature corn maze in Washington and the reason to make Snohomish your first stop. Beyond the maze there is a fifty acre pumpkin patch, an apple shack, cider and donuts, wagon rides, and a petting farm. Open daily, 10 a.m. to 6 p.m., through October 31.

Stocker Farms (Snohomish). A full day farm with pick your own pumpkins, a corn maze, and more than thirty attractions from jumping pillows to a mega slide and pig races, plus Stalker Farms, its haunted attractions after dark, for older kids. It opens on weekends in late September, then runs daily through October 31.

Craven Farm (Snohomish). A long running valley farm with a themed corn maze (Alice in Pumpkinland this year), a classic pumpkin patch, wagon rides, mini golf, and a jump pad. It has a quieter, more old fashioned feel than the big attraction farms. Open Wednesday through Sunday, 10 a.m. to 6 p.m., through November 1.

Bob’s Corn and Pumpkin Farm (Snohomish). The corn is the point here. Bob’s is known for its twelve acre maze, grown from corn that stands about ten feet tall, and its country store, with more than seventy pumpkin varieties on about 45 acres and covered hayrides out to the patch. The store opens for the season at the start of August, the fall festival runs daily through November 1, and a night maze runs Friday and Saturday evenings in October. Weekends are busy, so come early.

Thomas Family Farm (Snohomish). The after dark, higher energy option. Alongside the pumpkin patch, Thomas runs Zombie Paintball, a haunted house and haunted town, a flashlight corn maze, and escape rooms. The farm is open weekends only, through November 1, and the night attractions run Friday through Sunday evenings. They are aimed at teens and adults more than little kids.

Carleton Farm (Lake Stevens). A few minutes east in Lake Stevens, Carleton has a corn maze, a pumpkin patch, a petting zoo, hayrides, apple cannons, and a kids bucket train. Open weekends, Saturday 10 a.m. to 6 p.m. and Sunday 10 a.m. to 5 p.m. It pairs well with Swans Trail if you want to do two farms in one day.

South Sound: Puyallup Valley Patches

South of Seattle, the Puyallup valley is the other Puget Sound cluster, easy to reach from Tacoma and the South Sound. Our Puyallup city guide covers the wider area, and the valley is part of our Olympic Peninsula and South Sound region.

Spooner Farms (Puyallup). A sixth generation farm dating to 1882, out on Highway 162 southeast of town, with about fifty varieties of pumpkins, gourds and squash, a corn maze, and a harvest festival. It is the South Sound standard, and the same farm people know for strawberries in June. The Harvest Festival runs daily October 1 through October 31, 9 a.m. to 6 p.m.

Picha Farms (Puyallup). The valley’s other long running family patch, with a five acre corn maze built around American history trivia for the country’s 250th anniversary, more than twenty five kinds of pumpkins, hayrides, and weekend food vendors. Open October 3 through October 30, weekends 10 a.m. to 6 p.m. and weekdays 3 to 6 p.m.

Maris Farms (Buckley). Southeast toward Buckley, Maris runs a corn maze, a pumpkin patch, and one of the region’s better haunted attractions, the Haunted Woods, on fourteen select nights from late September through Halloween. The day farm is family friendly. The Haunted Woods is not: it takes its own ticket and is not recommended for kids under 12. Open Friday through Sunday in October.

North Central Washington: East Wenatchee

In apple country, the fall stop is on the east side of the river. East Wenatchee sits in our North Central Washington region, and our Wenatchee city guide covers the valley.

Annie’s Fun Farm (East Wenatchee). A family farm at Grant Road and South Mary Avenue that grows something for almost every month: strawberries in June, blueberries in July, sweet corn and melons in late summer, and Christmas trees in December. October is pumpkin season, with a pumpkin patch, apples and winter squash, and in recent seasons a corn maze, a petting zoo and games for the kids. Open daily this fall, 9 a.m. to 7 p.m. Check the farm’s Facebook page the week you go.

East of the Cascades: Green Bluff and Yakima

East of the Cascades the farms spread out, but two stops are worth knowing if you live over here. Green Bluff sits in Eastern Washington and Union Gap in South Central Washington.

Green Bluff: Monster Farm and Siemers (Spokane). Green Bluff is the loop of family farms on the bluff north of Spokane, and two of them anchor the fall. Monster Farm, formerly Knapp’s U-Pick Farm, has a pumpkin patch open daily 10 a.m. to 5 p.m. through October 31, with winter squash and gourds and a fall festival every Friday, Saturday and Sunday. Siemers Farm runs what it calls the state’s first and oldest running corn maze, plus a hedge maze, a three story castle, train and tractor rides, and a pick your own pumpkin patch, with its Fall Festival every weekend through November 1. Our full guide, Visiting Green Bluff Farms Near Spokane, walks the whole loop.

Union Gap Corn Maze and Pumpkin Patch (Union Gap). In the Yakima area, this is the local corn maze stop: a twelve acre maze, a kids mini maze and slides, pumpkin picking, hayrides, apple cannons, and barn food, with a haunted maze from 7 p.m. Wednesday through Saturday nights. It opened October 3 this year and runs through October 31, open Wednesday through Sunday, with evening hours only on Wednesday through Friday.

Southwest Washington: Clark County

In the Vancouver area, one farm carries the fall. Clark County is part of our Southwest Washington region.

Bi-Zi Farms (Brush Prairie). Just outside Vancouver in Brush Prairie, Bi-Zi runs a corn maze with a nighttime version on select October evenings, a wagon ride to the pumpkin field, a bale maze, hippity hop races, pumpkin launchers, farm animals, and weekend live music, with a free pumpkin and a hot drink included with admission. Open daily except Mondays through October 31, 10 a.m. to 6 p.m. Our full guide, Celebrate Fall at Bi-Zi Farms Pumpkin Patch, has the details.

One name you will see on older lists but should skip: Joe’s Place Farms, a longtime Vancouver favorite, has closed.

Picking a Farm: What to Check Before You Load the Car

A few things to check before you drive out.

Check the farm’s own page the week you go. Weather closures are common on the wet valley floors, and hours shift through the season.

Confirm weekends only versus daily. Many farms run the full maze and activity lineup on weekends only, even when the patch itself is open midweek.

Bring some cash. Some farms are cash friendly and not every stand takes cards.

Ask about the night maze. Flashlight and haunted versions run on specific evenings and usually sell separately from day admission.

Bring boots. The Snohomish valley floor turns to mud by the middle of October, and a stroller is a bad idea on most of these fields.

And one more east of Seattle: Remlinger Farms in Carnation pairs a full ride park with what it calls the biggest pick your own pumpkin patch in Washington. The pumpkin field is free to walk into and open every festival day, Friday through Sunday through November 1, so you can pick a pumpkin without buying a festival ticket.

Frequently Asked Questions

The season is six weekends long and the good farms are closer than you think. Snohomish County has the densest cluster and the signature state map maze, but every region has a real option, from the Puyallup valley to Green Bluff to Brush Prairie. Pick your region, check the weekend schedule the week you go, and bring boots. The corn will be up and the pumpkins will be out for about six weeks, and then they will not.
