We were in NG, a beautiful place, that is, in the winter this year, we rented a car and took a ride ourselves.
You won't be able to ride on a boat if you get there on your own. The boat is included in a package tour that costs € 35 per person. But we didn't need it.
So we drove to the pier where the ships sail from and took a walk around the neighborhood. On the way to the pier, we stopped and took photos, the area is very beautiful: mountains and turquoise water.
