Sněžka is the highest mountain in the Czech Republic with the height 1603 meters. It's also the highest mountain of Krkonoše, what are Czech greatest mountains. You can easily observe to the Czech Republic and to Poland (the north view), the borders to Poland are very close. You can refresh yourself in the buffet Česká Poštovna on the top of Sněžka. It’s a post office, you can also send a postcard from the top of Sněžka, what is quite interesting.
Ahoj!
