Røyken sits on the hilly neck of land between the Drammensfjord and the Oslofjord, south-west of Oslo, a mix of villages, farms, forests and commuter housing. It is a practical place to fill the tank before heading south through the Hurum peninsula or west towards Drammen and Telemark.
The area is linked to the eastern side of the Oslofjord by the Oslofjord tunnel, opened in 2000, which dives steeply under the fjord from Hurum to Drøbak. The tunnel is long and steep, with gradients that test heavy vehicles, and it has been upgraded to improve safety. For riders, it is a fast way across, though the descent and climb can feel endless.
The landscape around Røyken is gentle and green, with rolling farmland, patches of forest and views over the fjords. The villages are quiet, with old churches and farms, and the shore has beaches and small harbours popular in summer.
As a start and fuel stop, Røyken has service stations and shops. From here, the roads lead south along the fjord, west towards Drammen and the Telemark canal, or north towards Oslo. Traffic can be heavy on the main roads, especially at commuting times, but the minor roads are quiet. Speed limits are low and enforced, and speed cameras are common. Surfaces are generally good, though frost heave can make some roads bumpy.
