There are several buildings at the summit, including an open chapel and a huge radio mast. The panoramic view is very impressive.

The best way to get here is the hike path, not the gravel road.

Here at the ferry dock near entrance 2 you can cross the lake by boat. The crossing is free or included in the entrance fee.

This easy-to-walk staircase is the access from the Hotel "Jezero" or the car park down to the lakes.

It's a pretty bad road, but you can go up slowly in the first one, even with a small car

The closest approach to the shelter and the house on Bijeli stijene is by car. The road is mountainous, bad, but passable. A raised car is recommended, but you can also use a regular car.
