Visitors who hire a car in Nyköping can explore the area around this Baltic city, 6 miles south west of Stockholm. The city spreads across a very flat plain at the mouth of a small river but the surrounding countryside has attractive hills, lakes and woods. Skavsta airport is two miles out of town to the northwest, on the other side of the E4 trunk road that links Stockholm and Copenhagen. It’s a great region for taking day trips to by hiring a car in Nyköping; Sodermanland is also known for its stately homes and gardens, and fine old village churches. And for something very different, why not tour the secret cold war fortifications on the Oxelosund headland?
