Byrkjehaugen
On the farm Bø, close to the highway between Bulken and Voss lies Byrkjehaugen, one of the largest burial mounds in West Norway. Originally it was around 50m across and 5m high, but following the excavation in 1908 and chipping off by both railway and road construction, the cross-section has shrunk to 37m and the height to 4m. All the same, it is an impressive burial monument for the passing traveller to see.
Sysendalen
If you are lucky you can find 9000-year-old pine stumps on Hardangervidda. Since that time, the tree line has continuously declined. But now, it is on its way back up again.
Lurekalven
Lurekalven is an unpopulated island of heather moor which is a part of the wilderness belonging to the five farms on Ytre Lygra. Between the two islands there is only a small sound. As late as the 1920s, milking cows were rowed over the sound from Lygra in summer – a form of farming that was adapted to the coastal landscape.
