Montenegro (Tivat, Lovcen mountain)
I was in Montenegro in the winter, and I totally recommend this country for solo travelling at any time of a year! Really an incredible one ;)
Here is Tivat, small but cute town :)
Here is Tivat also. You can see these awesome colours, there are no filters at all, but blue one is everywhere :)
And when I was in Kotor (another small town), I had a tour to the Lovcen mountain (really great one!) and this photo was taken during the final climbing to the top.
