Goteborgs Golfklubb, the oldest club in Sweden, is not that far out and an interesting place to visit. I wouldn't say it was great golf, but it is quirky and there are some good holes. A little further from town, at Kungsbacka, is Vallda, a well regarded newish Hawtree design. You might also try the Hills club, designed by Steve Forrest and opened about eight years ago. I wasn't a huge fan, to be fair - un walkable and a few silly features. Forrest did better work at Vasatorps further down the coast imo.
