A varied 18-hole parkland course with an open layout and attractive green areas, located just outside the center of Mariefred, near Gripsholm Castle. The club also has a 6-hole short course. https://www.golfisverige.com/klubb/gripsholms-golfklubb/

Very impressive. The visit was worthwhile. The existence of the palace theater was particularly surprising.

The castle is ideal for a short break; the large parking lot is free and you can even get a snack.
