The town's beaches, like Tallparken and Gräsö, become popular spots for swimming and sunbathing, and there are often family-friendly events and festivals happening. The marina is bustling with boats, and there's a pleasant buzz around the town square, particularly in July.Couples will also find the summer months offer a lovely setting for a romantic getaway. You can enjoy evening strolls along the harbour, dine at charming waterfront restaurants, and take advantage of the extended daylight for scenic boat trips or cycling along the coast.
