There is no better place to spend sunny days then Stockholm. Sometimes called the Venice of the North because water is always close. The pride here is that this water is so clean that one can jump in whenever one feels like cooling down.
The Fredhaell neighborhood has a historic swimming spot where it is easy to step in and out of the water. It is our preferred place to have a morning swim.
In the evening the cliffs close by are used for picnics before a jump in the lake. I do not know how they come out again….
