Northern Ostrobothnia Museum

The beautiful park of Hupisaaret (lit. Fun Islands) is a lush area with little paths and bridges crossing beautiful little streams. The longest fish path of Finland, 750-m- and 64-stair-long fish path is on the northern part of Hupisaaret park. Take a picnic or just stroll around the renovated park where you can also find the soon-to-be-mentioned Northern Ostrobothnia Museum. Tietomaa and Oulu Museum of Art are also found near the park.

Neoclassical Lutheran cathedral built in 1832 after its predecessor burned down. The architect Carl Ludvig Engel also designed the buildings of Senate Square in Helsinki.

The castle was damaged by attack in the 18th century and finally blown to pieces in 1793 when lightning struck the gunpowder magazine. What you see now is the maritime observatory built on the ruins; it's set in a pleasant park, and you can climb the tower for views. There's a café (Tähtitornin kahvila) within. The cellar (same hours) displays info on the castle - mostly in Finnish, but there's more in the Northern Ostrobothnia Museum.

Two-storey museum with a wide variety of modern artwork. Around 8 exhibits a year. Plenty of information in English, except for small, temporary exhibits.

Closed for renovation until 2026 The oldest science museum in the country, mostly kinematic and interactive, great for pre-teens but plenty for adults to enjoy. It is partially located in the former Åström leather factory, and you can ride the glass lift up the 19th-century brick water tower.

A "water park" meaning a floated obstacle course in the Oulu river delta. Right next to the Oulu castle ruins and cafe, so you can get a coffee or a cold beer after!
