The Harz is a hiker's and walker's paradise and is criss-crossed by trails of every conceivable length and difficulty. Many of the longer trails are named: the Goethe Way (Goetheweg), the Kings and Emperors' Way, the Inner German Border Way, and the Harz Witches' Path (Harzer Hexenstieg) to name a few. In order to encourage fitness and tourism, the Harzer Wandernadel was founded a few years ago. They established a network of checkpoints and a badge system based on the number of checkpoints visited. Thousands of hikers, young and old, have participated in the scheme. This is a great way to explore the Harz as the checkpoints are sited at places of interest: lofty crags, medieval castles, museums, lakes, view points, and hilltops. The pass books (€2) and map sets (€7.50) may be purchased in most information and tourist offices in the region as well as participating restaurants and museums or online.
