Trehyttene i Gjerstad in Norway are three tree houses located in the forest at Gjerstad (about 45 minute drive from Risør). The first one is called Kråkeslottet (Crow’s castle) with electricity and modern facilities. The second is called Gjøkeredet (cuckoo’s nest) which is actually suspended in the trees without electricity.
These tree houses are the only ones in existence in southern Norway and they are brand new. No expense has been spared in making them with top quality bedding, furniture and appliances. This is one holiday you will never forget.
