Norway
You'll need a bike to get out of the city and on to Bygdoy - there is a bus, but it only goes to the museums. Cycling through the royal estate, through hayfields and pine forests, you'll come first to a lovely sandy cove at Paradisbukta, and then to Huk, at the very end of the peninsula, where you can swim clad (near the restaurant) or naked (a little further north). A little touch of wilderness 20 minutes' bike ride from City Hall.
