Not just caves but also bunkers

Not just caves but also bunkers
A hole in the ground can be an entrance to a Soviet Bunker

In addition to caves, you can find other underground sites such as partly demolished Soviet second world war bunkers in Finland. These are interesting sites that you should consider visiting.

We recommend you visit Jari Arkko’s website, which acts as an index to his caving related posts. There you will find blog posts on Finnish caves and bunkers.

Remember to be extra careful when visiting bunkers!
