The Numedal trail stretches from Geilo via Kongsberg to Larvik through beautiful, diversified landscapes. For most of the way it follows the river Numedalslågen, Norway´s second longest river, and it is steep, with a fall of as much as 1000 metres. The route is relaxing, with little traffic. Thanks to an excellent public transport network you can start and end your cycling trip whereever and whenever you wish. There are excellent train services to Geilo, Kongsberg and Larvik, and busses run several times a day between all three towns, in both directions.

Some routes are particularly suitable for children, Dagalifjell to Rødberg (43,5 km through beautiful summer dairy farming districts), Veggli - Rollag (16 km) is flat and runs past sun-drenched cabins and houses dating back to the Middle Ages. and Brufoss - Larvik (57 km along Numedalslågen on quiet roads with little traffic).
The route from Brufoss to Larvik is signposted with special signposts. The route between Geilo and Brufoss is signposted since summer 2001.
