secret underground world of dalmatia

About maricevac tunnel

Maricevac is a tunnel with one of the most peculiar stories you’ll ever hear. It was made 100 years ago to take the water away from Jezero valley and make life more bearable for the locals who lived there. The tunnel is 2 kilometers long and it was dug without any machinery. Jezero valley was once a huge lake and locals were unable to grow any food on the bottom of this lake which was once a fertile valley, just like it is today. The only solution was to dig this tunnel and let the Matica river flow through it, first into the Bacina lakes and then from Bacina lakes into the sea.

And that’s how the Jezero valley became fertile soil once more. This tunnel still takes away the floods during the rainy seasons and it’s possible to pass through it only in the summer months. Take this unique opportunity and embark on a journey through the past while discovering all the secrets of this life-changing project.

We start this tour in Peracko blato, a village on the shores of Bacina lakes. Although the tour is done in the middle of the day, the temperature in the tunnel is like in the air-conditioned room and we suggest you take a shirt with long sleeves with you. Most of the tour is done in the tunnel and you won’t feel any heat at all. We meet on the parking lot of the main beach in Peracko blato and enter the Maricevac tunnel where we’ll spend the next hour and a half.

The bottom of the tunnel is made of concrete and it’s perfectly easy to walk on it. Our guides will guide you through the tour and you’ll find out every single detail about this peculiar tunnel. We’ll show you archive photos from the days this tunnel was being built. You’ll have the unique opportunity to observe the underground world of Dalmatia. Every guest on the tour gets his own headlamp.
