Always check the opening hours beforehand! There is a cozy fireplace inside, as well as an outdoor patio where you can enjoy food and drinks.

The Norwegian Museum of Science and Technology, founded in 1914 and housed in its current Kjelsås building since 1986, chronicles Norway's transformation from an agricultural to an industrial society through extensive collections covering transport, energy, medicine, and technology. The museum serves as an anchor point on the European Route of Industrial Heritage and features permanent exhibitions on topics ranging from aviation and oil industry to computing and timekeeping. Notably, the museum houses what is believed to be the world's oldest surviving steamroller, dating from 1878 and acquired directly from Oslo's road department.

I recommend climbing Grefsenkollen, especially in the evening light. The sunset over Oslo is magical from here. You can also take a sauna at the summit. However, it can get quite crowded, especially in spring and summer.

Nice picnic spot of Setertjen. Located in the middle of the forest it is a perfect location for a break.
