You see there is always something new to explore. Keep calm and bike on.
Accomodation: The czech hotels are way cheeper than the german ones. So we recommend you to stay either in Jachymov or in Bozi Dar. Rooms start at 10 €/night incl. breakfast. Right at the beginning of some trails, there is a nice camping site in Rabenberg if you prefer to sleep in your van or in a tent.
Food: The Czech hearty dishes are very tasty and recommendable and in addition you should try the delicious Czech beer. The costs for 2 people for a meal (including beer tasting ) are about 15 – 20 €.
