The Oslofjord is a large protected inlet with many islands of varying sizes dotted with hundreds of small cabins. The Oslofjord is not a fjord (a long, narrow, deep inlet of the sea between high cliffs) in the geological sense. In Norwegian, the term “fjord” can refer to a wide range of waterways. The bay is divided into the inner and outer fjord.
