Østby is a village in Trysil municipality, Innlandet county, Norway. The population of the village in 2003 was 205,[2] but since 2004 it has not been considered an urban settlement by Statistics Norway, and its data is therefore no longer tracked separately. (Locals say that about 200 people live there).[3]
In Østby, there is a community house, a supermarket, an abandoned school, Østby Church and a hotel, the Kjølen Hotell, which is well known as a training location for cross country events: in the area surrounding Østby are several cross country tracks of which some are illuminated. Every year the Trysil Skimaraton (42195) takes place in Østby, the starting point of which is the hotel. The Norwegian National Road 25 runs through the village, about east of the border with Sweden.[4]
