Byfjorden
Swimming and fishing is fully possible in Byfjorden (By Fjord). The water is of good quality most places, after considerable resources have been used in past years for clean-up. But, past sins still lie in the mud on the sea bottom. Fish that live in direct contact with the bottom sludge should not be eaten.
Nordåsvatnet
The Post-war Era came to Fana with its population growth and modern sanitary equipment. This had nearly catastrophic consequences for Nordåsvatnet as a recreational area. After the runoff water got re-directed to deeper water, and later also to the fjord outside, Lake Nordås won back both its swimming guests and its sports fishermen.
Kollevågen
From 1938 until 1975 there was a large amount of trash dumped in Kollevågen. A lot of the garbage from the city of Bergen ended up here. The dump was up to 20 metres high, and much got dumped under water in the bay. When the dump was closed, the time had come to make good on a municipal promise to make the place into a recreation area. In 1978, nets and earth were laid over the dump, and afterward it was sowed with seeds. This was quite successful, and In 1983, the recreation area was opened.
Fjell river network
There are many river networks out by the coast and they tend to be small and unassuming. The farmer has relied upon the watercourses to run his mill and saw, and it may be that the trout have given him a good source of food in years when the ocean fish failed. In our time, these river networks are being rediscovered for their value in recreation and outdoor life, and several places, tourist trails have been built in order to fully enjoy them.
Landro
Landro has been the largest estate on Sotra, including 15 farms with reasonable conditions for agriculture. Their boathouses have had an excellent harbour in Landrovågen. Landro thus has been a good basis for the combination of agriculture and fishing.
Frøland
Much rain, a steep drop and nearness to Bergen meant that the power-making potential of the Samnanger water system was exploited early. Samnanger was thus one of the first power-producing municipalities in western Norway. With its subsequent expansion and new power stations, about 400 gigawatts of electricity per hour were produced on average each year. This is enough to meet the energy needs of 25,000 households.
