You reach the campsite via road number 210 from Söderköping towards St. Anna and Norra Finnö (road signs "Sankt Anna" and N. Finnö). When you reach St. Anna's Church, turn right towards the church (and Kalvholms Camping), after about 500 meters you will pass a school on the right hand side and a church on the left hand side. Run between the stone posts and keep going straight ahead on a narrow dirt road (private road) approximately 1 km and there you'll find Kalvholmens Camping. You will find a road description from Söderköping here.
