Visit Nynäshamn


There are many caves in Nynäshamn with surroundings. Some are a bit hard to find and explore and some are very easy accessible. When planning an excursion to a cave, there are some things to consider. It often gets wet, messy and dark. Therefore, it is a good idea to wear overalls and a helmet equipped with a headlamp. But most important is: Don't go alone!
