Here you could cross over with the ferryman on the small Booz before the new bridge was built nearby

A beautiful bridge at the crossing of Mali into Veliko jezero. A solid place to bathe (although places on the north side may be better).

Separation between Malo Jezero and Veliko Jezero, so small and large lake.

The trail leads into the nature reserve from Pomena on stone steps through a forest. If you have climbed the highest point, open up in front of one of the "Little Sea". The views between the trees are outstanding. The last few meters to the merger between "Small Lake" and "Big Lake" you have to share with the mountain bikers, but is not a problem.

The "Small" and the "Big Lake" have different heights. They are connected by a brick channel. Due to the differences in altitude, the water flows from the Great Lake at a high flow rate into the Small Lake. This is an event for the bathers. They can be drifted from the Big Lake to the Little Lake like in an accelerator. Both lakes used to be freshwater lakes. After the monks built their monastery on the island in the Great Lake and found that they had to fight with mosquitoes and Malariamücken, they created a connection to the sea. The lakes have since been saltwater lakes and much warmer than the Mediterranean, which encloses the island of Mjlet.
