You end the day in Bærum, the big, comfortable municipality that runs west from Oslo along the fjord, and Sandvika is its centre: a cluster of offices, shopping and apartment blocks where two rivers come out into a sheltered inlet. It is suburban, yes, but suburban with sea water, small islands and wooded hills behind, and after a long ride through mountain country that is not a bad place to roll to a halt.
The hills you see behind Sandvika are the edge of Vestmarka and Krokskogen, big forests that Oslo people treat as their back garden, full of lakes, cabins and ski tracks. In the other direction lies the inner Oslofjord, dotted with islands. Kalvøya, just off Sandvika, is a green island reached on foot over a bridge and became famous for open-air rock festivals in the 1970s and 1980s. A short way east along the shore at Høvikodden, the Henie Onstad Art Centre was founded by the Olympic figure skater Sonja Henie and her husband, and its collection of modern art and the sculpture park on the point are well worth an hour if you still have the energy.
Riding in is mostly a matter of motorway and traffic. The E18 and E16 meet here and carry heavy commuter flows, and rush hour around Sandvika can be slow, with tunnels, merging lanes and speed cameras. Norway runs automatic toll stations around Oslo and Bærum, charged by registration plate, so if you are on a foreign bike, register in advance or expect an invoice to follow you home. Lane filtering is not legal, so patience is the only option.
The good news is that everything is here. Sandvika has fuel stations, supermarkets, a large shopping centre and plenty of places to eat, and the train into central Oslo takes just a few minutes if you want to park the bike and go out for the evening. The fjord path along the shore is pleasant for a walk once the helmet is off.
It is worth thinking back over the miles. Behind you lie the canal locks of Telemark or the switchbacks of Trollstigen and Geiranger, depending on which ride brought you here, and for a big tour the gentle lights of Bærum at dusk feel like a calm full stop. Get the bike under cover, find something to eat, and let the corners settle in your head.
