If you take the sea route north you have several options. The various routes have been dealt with in history, and through the Middle Ages the traffic increased as well as the trading with Nordland in fish and herring, feather and down. One of the central routes passes through Kjelstraumen, in the sound between Ulvøy and Bakkøy. This has been a place for a guesthouse since 1610, with Royal Letter of Privilege, part of the large network of trading post and guesthouse locations along the coast.
The pioneering tourists in the 1830s-40s brought a momentum in the tourist traffic to the fjord and mountain country Norway. At the time Odda was a hidden Shangri-La at the bottom of Sørfjorden; the farm and the church on the green headland at the fjord. But when the steamship traffic opened the fjord landscape for tourism, in a few years Odda parish in Søndre Bergenhus County became the focal point for travellers in West Norway.
