When visiting Jotunheimen be aware that there are a large number of entry points to the National Park and places to stay.
Jotunheimen is surrounded by several villages and all of them have a good number of listed houses and apartments on Airbnb.
Some entry points are located further into or at the National Park border. There are usually no Airbnb listings in these areas, as no one is living there. But, all these entry points have great mountain lodges that serves local food (all meals) and it´s possible to book a room or at least a bed for the night.
For everyone with a tent, there are numerous places to stay along the roads or at one of the many campsites surrounding the national park.
