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.
Yddal
Yddal is one of the biggest and finest pine forest areas in the county. The rich forest resources provided an important foundation for the settlement of Yddal. Up until about the 1950s, there were three farms here. Where the lumberjacks couldn't get to, the trees grew very big and can be over 300 years old.
