7. The Douro, Portugal
It`s unfortunate that from a couple of years ago Douro `s popularity and its banks are ruined by human “progress”. Things are not that bad (for now) because you can still feel the 19-th century charms running through its veins.
8. The Neretva, Bosnia and Herzegovina
Neretva has one of the cleanest, emerald-green waters you`ll ever see. Its water is so good is almost) if not) close to drinking standards in the source (springs). The city of Mostar with its 16th century bridge is one of the most scenic spots along the way.
