the week before the International Film Festival has started, I've visited with a friend Karlovy Vary/Carlsbad the first time and need to say, that the old part of the town is magical and historical and full of good healing water springs!;)
Carlsbad is well known as a spa town, people from all over Czech Republic but as well Germany, Russia and other neighbor countries are each year booking a vacation or thermal spa stay in this old town near Prague.
The water tastes at each place (more than 10 are open for public in the whole town!) a bit different, depends on the quantity of minerals, vitamines as well as oxygen.
It's a lovely town, to stay for a day, a week (at one of the local spa's) or during your roadtrip through Czech;)
