Göteborg skärgård by boat/ferry = romantic islands

Hej-hej,

Soon I'm in Gothenburg and I decided that I would love to spend more time out in the nature than I usually do. :)

Which ö (this word will always make me laugh a little) would you recommend me there for visiting? Something which is relative close to the Centrum of Göteborg, but I could get a great view or it has some attractions/historical parts.
