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

Somewhere in a field outside Snohomish, ten 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 real highways and town names carved into the rows, and it takes about an hour to cross the state on foot. That maze, at The Farm at Swans Trail, 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 from the middle to the end of September, the sweet spot is late September through the middle of October, and almost everything shuts down on October 31. 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. Farms open from the middle to the end of September, when the fields are fresh and the crowds are light. 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.

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 of Deception Dark 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 flashlight maze nights at Craven, the haunted maze at Union Gap, and the night maze at Bi-Zi. They run on specific evenings, usually Friday and Saturday, and they 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.

The Farm at Swans Trail (Snohomish). This is the one with the Washington State map. Every year the farm cuts its ten acre corn maze into the shape of the state, real highways and towns and all, so you can walk from the coast to the Idaho line through the corn. 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 from late September 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 the Haunted Stalker Farms after dark for older kids. Fall days run from late September through the end of October. Our full guide, Visiting Stocker Farms for Fall Days, has the deep version.

Craven Farm (Snohomish). A long running valley farm with a fifteen acre themed corn maze, a classic pumpkin patch, hayrides, mini golf, and jump pads. It has a quieter, more old fashioned feel than the big attraction farms. Weekends in September, then Wednesday through Sunday in October, with flashlight maze nights on the October weekends.

Bob’s Corn and Pumpkin Farm (Snohomish). The corn is the point here. Bob’s is known for its maze, grown from corn that stands well over ten feet tall by October, and its farm stand, with more than forty acres of pumpkins in sixty varieties and a tractor tour of the property. The farm reopens for the season around the start of August and runs through the fall. 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, a haunted hayride, and escape rooms. The night attractions run Friday and Saturday evenings and are aimed at teens and adults more than little kids.

Carleton Farm (Lake Stevens). A few minutes east in Lake Stevens, Carleton grows a new corn maze design every year, from tractors to animals to a pig in a barn, alongside a pumpkin patch, a petting zoo, hayrides, apple cannons, a kids train, and the Carleton Farm Frights after dark. Open weekends. 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.

Spooner Farms (Puyallup). A sixth generation farm dating to 1882, out on Highway 162 southeast of town, with a pumpkin patch of more than fifty varieties, a corn maze, and a harvest festival. It is the South Sound standard, and the same farm people know for strawberries in June. The season runs the usual late September into October window, so confirm the current year’s dates on their site before you go.

Picha Farms (Puyallup). The valley’s other long running family patch, with a five acre trivia corn maze that hands out a free mini pumpkin at the exit, twenty five kinds of pumpkins, hayrides, and weekend food vendors. Open weekends and weekday afternoons in season.

Maris Farms (Buckley). Southeast toward Buckley, Maris runs a themed corn maze, a pumpkin patch, and one of the region’s better haunted attractions, the Haunted Woods, on select nights from late September through Halloween. The day farm is family friendly. The Haunted Woods is not. Open Friday through Sunday in October.

Eastern Washington: Wenatchee, Green Bluff and Yakima

East of the Cascades the farms spread out, but three stops are worth knowing if you live over here.

Stutzman Ranch (Wenatchee). A century old pick your own fruit ranch in apple country. Be clear on what this is: it is a pick your own operation for apples, pears, and grapes, not a corn maze farm, and the pumpkins arrive in mid September as the picking season is winding down. If you want orchard country and a pumpkin on the way out, it fits. If you want a maze and rides, look elsewhere. Our Wenatchee city guide covers the valley.

Green Bluff: Knapp’s and Siemers (Spokane). Green Bluff is the loop of family farms on the bluff north of Spokane, and two of them anchor the fall. Knapp’s U-Pick Farm has a five acre pumpkin patch, more than forty squash varieties, a straw maze with singing pumpkins, and hayrides. Siemers Farm runs a longstanding corn and hedge maze and adds a multi level castle, train and tractor rides, and its own pumpkin patch. Both run on the Green Bluff festival weekends from late September through October. 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 on weekend nights. It opens in early October, and opening weekend is usually discounted.

Southwest Washington: Clark County

In the Vancouver area, one farm carries the fall.

Bi-Zi Farms (Brush Prairie). Just outside Vancouver in Brush Prairie, Bi-Zi runs a seven acre corn maze with a nighttime version on Friday and Saturday, a hayride, a bale maze, duck races, pumpkin launchers, pony rides, farm animals, and live music, with a free pumpkin and a hot drink included with admission. Open daily except Tuesdays through October. 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 heads up on a farm you will see on other lists: Remlinger Farms in Carnation, east of Seattle in King County, is no longer a classic patch. It has become a rides and attractions family park with only a limited pumpkin picking window, so go for the amusement park, not the produce.

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.
