There are three airports located close to Oslo, Oslo Airport Gardemoen (OSL), Moss Airport Rygge (RYG) and Torp Airport (TRF). Gardemoen the closest airport and perhaps the easiest one to use considering that you have regularly scheduled train departures headed for Oslo. Depending on where your flying from Torp and Rygge might be cheaper, but it takes longer to get into Oslo.
If you arrive at Gardemoen – take Flytoget or NSB from Oslo Lufthavn to Oslo Central Station
If you arrive at Torp – take the Torp Ekspressen airport bus to Oslo Central Station
If you arrive at Rygge – take Rygge-Ekspressen to Oslo Bus Station (which is 2 min away from Oslo Central Station)
Our Office is easy to get to by using trains or taxis from Oslo Central Station
