Ochiul Beiului is actually a small lake with a beautiful turquoise water which can be found in the Cheile Nerei-Beușnița National Park. In order to get there, you will have to drive to Beiului trout farm. Over there you can leave your car while visiting the place. If you plan to eat something before your journey to Ochiul Beiului, you can find there a small restaurant where you can eat some fresh mountain trout. Besides the restaurant, there is also a camping place.
Right before the entrance into the trout farm, you will find a marked path which will take you through the forest to Ochiul Beiului. After about 45 minutes of walking through the forest, next to a mountain stream, you will reach the small lake with turquoise water.
