Contrary to its name, Portland's Saturday Market is open on Saturday 10-5 AND Sunday 11-4:30. It's a massive open air arts and crafts market! There are vendors selling all sorts of things, and if you get hungry, there are food carts there as well!
Want to get outside? Go check out Washington Park and get lost in it! There are a bunch of trails as well as the Zoo, World Forestry Center, the Japanese Garden, and the International Rose Test Garden. Yes, the Roses are still blooming in October!
We, regrettably, have never been to see this. But every October St.Helens, OR sets up their town square to look like Halloweentown. It was filmed there, it's their schtick. There's a fun little festival and they have the big pumpkin and everything. Do it for the gram.
PIZZA! We love this place! they also often have bands and things performing in the dinning room. One time Emily went there to pick up a pizza and while she was waiting stumble upon a band dressed as pirates who only played songs from the 'Muppet Treasure Island' soundtrack. Portland's weird.
