Valley of the Five Lakes
Tucked way up in the High Tatras mountain range and running along the Polish/Slovakian border, these five alpine lakes each boast glassy, cerulean-tinted water. Just how glassy can water be, though? Well, judging from this video shot by hikers last December, pretty damn glassy.
The largest of the lakes, Morskie Oko (or "Eye of the Sea"), is also the most popular for tourists hiking the High Tatras, and was chosen as one of the most beautiful lakes in the world by the Wall Street Journal. Totally a big deal among lake enthusiasts.
