The farm features thrilling seasonal attractions including pumpkin cannons that launch gourds into the canyon, a scenic barrel train pulled by a tractor, giant tube slides, straw bale mazes, and obstacle courses. Families can hop on tractor-pulled hayrides through the wooded farm perimeter to pick carving pumpkins, visit friendly farm animals in the petting barn (goats, sheep, pigs, and bunnies), and enjoy fresh apple cider donuts warm from the fryer. Family Experience & Accessibility: • Stroller Accessibility: The main central courtyard has compacted gravel paths; all-terrain strollers or baby carriers are ideal for navigating hillside play areas and pumpkin fields. • Nursing & Rest Spots: Sheltered timber-frame picnic barn with bench seating and hand-washing stations; clean restrooms equipped with baby changing tables. • Age Suitability: Outstanding for toddlers, preschoolers, and elementary schoolers through age 12. • Sensory Tips: The pumpkin cannon produces occasional loud thuds; helpful warning signs allow families with sound-sensitive children to observe the launch from a comfortable distance. ## Similar picks in Portland - [The Pumpkin Patch on Sauvie Island Autumn Harvest & Corn Maze](https://grassyknees.com/portland/activities/the-pumpkin-patch-on-sauvie-island-autumn-harvest-and-corn-maze--listing-e5941052e3269195ddacc8ec) — Open on its own schedule · The Pumpkin Patch on Sauvie Island · All ages · Free · checked Nov 5.
