Context

Our verdict

Geilo, Norwegian ski resort on the Oslo-Bergen railway in Hallingdal : 2400 inhabitants at 2,600 ft altitude between Hardangervidda and Hallingskarvet national parks. Oldest tourist ski resort in Norway = developed from 1909 when the Oslo-Bergen railway was inaugurated crossing Geilo, more traditional and family atmosphere than neighbouring more festive Hemsedal.
