As you would expect, Bavaria has the full range of accommodation common in Western Europe, from basic campsites to five-star luxury.
DJH youth hostels in Bavaria accept guests aged over 27 (who pay a €4 surcharge), although priority is still given to younger travellers. Independent, all-age hostels in Nuremberg, Bamberg and Würzburg are a less institutional alternative.
Bavaria’s parks are generally open to free camping. Parks such as the Altmühltal Nature Park restrict camping to designated areas, for a small fee. Be sure to follow the local code of ethics and common decency, and pack up everything you brought along – litter, bottles, cans – and bury human waste before you leave.
