We are a family with children (5-15 years) and planning to spend our vacation from 5th AUGUST-24th August between Sweden and Norway. we are flying to Stockholm and our flight return from Oslo. we will rent a car and we prefer to stay away from the city. we prefer lakes, mountains and nature and water parks. the first 4 night we will stay in a house 20 km from stockholm. what other places we can spend time there. I would appreciate your suggestions.
