Grefsenkollen
Grefsenkollen is the great northern balcony over Oslo. It gives wide views over the city, the fjord, Holmenkollen and the surrounding forest and has long been a favourite for evening light, food with a view and easy-access hiking. It works especially well because it combines a strong panorama with a relaxed outing atmosphere.
It is a very good choice for sunset, for dinner with a view, and for visitors who want a large panorama without needing to hike deep into the forest. Public transport is possible, but the simplest approach is to check the current journey planner before going because the best route depends on where you are starting from.
