Free WiFi is available throughout the house.
Bad Belzig itself offers some beautiful highlights, e.g. the SteinTherme, Eisenhardt Castle and the Kunstwanderweg hiking trail. If you want to go further, you can explore the Hohe Fläming as well as do day trips to Dessau, Potsdam or Brandenburg an der Havel. The hostel parents are available for hiking tips and even offer a "hiking and cooking" package.
