"It was cold in October but the water was still swimmable. We put some drinks in the water to chill and they all floated away."
Go: Take the ferry out of Stockholm towards Husarö and get off at Boda Brygga. It cost 130 Swedish krona and the sea route is worth the extra hour of travel.
Stay: After a day on the coast, book your stay at Hotel Skeppsholmen, the design savvy Marine barracks in the heart of the city. Rates hover around 1300 Swedish krona.
Eat: Pack a lunch of knäckebröd (a hard bread) and smoked whitefish before heading out. While there, pick blueberries, wild mushrooms, and apples from the neighbor's tree (quickly)!
Drink: Brännvin is Swedish vodka, literally meaning 'burn-wine.' It will surely warm you up after a swim and on the breezy ferry ride back.
