East Bohemia is popular with tourists. It is mainly because of the Krkonose Mountains (the Giant Mountains). The Giant Mountains are the highest mountain range in the Czech Republic. The highest peak reaching the height of 1602 m is called Snezka. The Giant Mountains were declared a natural reservation and a national park in 1963. Here you can find a spring of the longest Czech river Labe flowing into the North Sea. Krkonose with its alpine and artic climate are an ideal place for skiing, mountaineering or climbing. There are a number of resorts, which live up to all standards for a pleasant holiday. The small mountain town Vrchlabí may become a good starting point to get to know Krkonose. The Krkonose Museum with its mineralogy and geology collections is the main tourist spot of the town. It is also worth making a short walk round the town, where you can admire remains of half-timbered houses from the 18th and 19th centuries and a baroque stone bridge across the river Labe. The most important and most visited mountain resorts in Krkonose are: Spindleruv Mlýn, the largest one, Pec pod Snezkou and Harrachov. Spindleruv Mlýn offers excellent conditions for walking, cross-country or downhill skiing. Plenty of hiking tours to another holiday resorts such as Pec pod Snezkou, Horní Mísecky, Labská bouda etc. start in Spindleruv Mlýn. Real paradise for all downhill skiers is the village of St. Peter (only 2 km from Spindleruv Mlýn) with slopes for both beginners as well as experienced skiers. Some top ski competitions take place here from time to time. If you are one of cross-country skiing enthusiasts, you certainly must come to Plán, a starting point for tracks of various lengths and difficulties. Here you will have a chance to discover the silent world of the magic Krkonose ridges. Pec pod Snezkou is the second largest resort in the Krkonose Mountains. It offers plenty of walking and hiking tours, which can take you to interesting places such as Cerný Dul, Luciny or Spindleruv Mlýn. This centre is also sought for its excellent skiing conditions. Harrachov, the last of the three largest winter sport centres of this region, is well known not only as a winter resort, but also as a town of glass. Harrachov is located in the Mumlava river valley; the waterfalls of this river drop more than 10 m down into the valley and are certainly worth seeing. One of the biggest ski springboards in the world where Dare-Devil World Championship in ski flying takes place is called Rýzoviste.
