I recommend a day trip to Hardanger Fjord. You first drive south from Bømlo along the E39 to the E139 and then follow it east. Along the narrow Åkrafjord, which is surrounded by steep cliffs, you pass the Langfoss waterfall, which is Norway’s fifth highest waterfall at 612 meters. According to CNN Travel, it is one of the 10 most beautiful waterfalls in the world.
Further east, the E139 leads towards Odda. On the way to the Odda Valley you will see many waterfalls, including the famous Låtefoss. From Odda you drive a short distance west to Sørfjorden towards Rosendal and use the tunnel under Folgefonna (Norway’s third largest glacier). There are several options to stop here to view the glacier.
I also recommend a stop in Rosendal. There are many sights here, so that a separate day trip to this place is worthwhile. Rosendal is home to Norway’s only barony, with its beautiful park and Folgefonna Center. During the summer months, great concerts with Norwegian artists take place in the courtyard of the Baronie in the evenings.http://www.baroniet.no/en/.
From Rosendal the trail continues along the Hardangerfjord, through a tunnel under the sea to Halsnøy, by ferry to Stord and then over the bridge back to Bømlo.
