There's another new route to the village if one decide not to go through the old part right??

No, it's just the new part that can be approached by car and if you want, you can stay there. But to see the old part and these views, the route I showed is the only one. Then, once you are up in the old part, just that one street is there and a small square from where the lake can be seen. From there we can just go back, it's a dead end path :D
