Midsummer is the longest day and I spent one of the most beautiful nights ever on a beach watching the light not fade. And, if you like seafood, chardonnay and vodka, the crayfish festival is the best way to round off the summer. I lived in Gothenburg for five years and to me it is the heart of Sweden. If you go to Sweden, go to Gothenburg.
The annual crayfish parties are held throughout Sweden on Midsummer's Eve in June.
