The competition can get fierce with racers trying to outmaneuver each other on the Lake at the Commons.
Since 2004, this cherished local free event has returned to the Tualatin Commons every October with a series of races. The races are exactly what they sound like: costumed competitors piloting a gaggle of gigantic gourds through a watercourse on Tualatin Lake at the Commons. The regatta kicks off the day before the races with a pumpkin weigh-off at the Pumpkins and Pints event at Stickmen Brewing Company. The following day consists of a full day of pumpkin paddlers plying the shallow lake in giant pumpkin boats.

Questions About Giant Pumpkins
What is the world’s biggest pumpkin?
Competitive giant vegetable growing has participants all over the world. And, interestingly enough, 2020 saw somewhat of a resurgence in the hobby. New records were set in many areas, such as the heaviest red cabbage at 70 pounds (32 kg) and a four-foot-long (1.2 m) leek. That year, the biggest pumpkin was grown in California and weighed 2350 pounds (1066 kg). However, it didn’t beat the all-time world record, weighing in at 2,819 pounds (1,278 kg) grown in 2025.
Can you really use a pumpkin as a boat?
Pumpkins, like apples, are buoyant. Meaning they are less dense than water and, therefore, float. As a matter of fact, the world record for the longest pumpkin boat journey is held by a man in Oregon who skippered his stupendous squash a whopping 58.57 miles (94.26 km) down the Red River — in fact, he got his start in the world of giant pumpkins by participating in the West Coast Giant Pumpkin Regatta!
How long does it take to grow a giant pumpkin?
It can take anywhere from 140 to 160 days to grow a giant pumpkin. The general rule is 60 days of plant growth and 90 days of fruit growth. However, growing the biggest possible pumpkin involves getting the perfect balance of nutrients, light and fertilization. Find some tips here from a member of the Pacific Giant Vegetable Growers.
On dry land, a kid’s costume contest and other seasonal festivities will keep the laughs coming at this free, family-friendly event.
