With an area matching that of Vienna, The Jizera Mountains are best tackled multiple times or over a few days, at least. They form part of The Sudetes and comprise of a mountain system stretching from Dresden in Germany to Poland, dipping into Northern Bohemia in The Czech Republic. The slopes are relatively easy to tackle, with gentle inclines, which make it ideal for strollers and cyclists. In summer outdoor enthusiasts trickle though its trials and come winter, the celebrated Jizerská 50 kicks off. This consists of the famed cross-country ski championship of 50 kilometres known throughout Czech lands.
