Fasting hike September 2026

Fasting hikes combine two practices that have each been established for decades on their own. On one side, Buchinger fasting, developed by Otto Buchinger in the early 20th century. On the other side, guided hiking in a small group. The combination is more than the sum of its parts, because the movement carries the fast more easily and the fast turns the hiking day into a more deliberate experience. Your daily rhythm is calm and clearly structured. In the morning you start with a warm fasting drink, often a cup of tea with a little honey or a diluted juice. Then comes the main walk, usually three to five hours at a moderate pace, with breaks at viewpoints and a quiet midday rest. At noon you receive a small bowl of vegetable broth, plus plenty of still water and herbal tea. The afternoon is for rest, reading, a massage or a sauna round, depending on the house and the day. In the evening you have broth again or a diluted fresh juice. The weeks classically start with one or two preparation days on which you eat light rice meals or fruit, followed by four to five pure fasting days and one or two build-up days at the end with slowly returning solid food. These phases are part of the method, because your body should not be loaded abruptly after the fast. You do not go home hungry, you go home settled.

Fasting hikes thrive on a calm, hilly landscape with well marked trails, fresh air and forests that comfortably yield three to five hour day legs without pushing you into real high alpine demands. That is exactly why the German low mountain ranges are the heartland of these weeks. In the Black Forest, with its gentle valleys around Freudenstadt, Hinterzarten and the Hochschwarzwald plateau, you find a broad selection of weeks, often in spring and autumn. The Allgäu in southern Bavaria offers similar conditions with a foothill character and many simple hiking guesthouses. The Eifel and the neighbouring Westerwald in Rhineland-Palatinate form a further focus, with volcanic cone routes and quiet monastery landscapes. In the Harz mountains, around Clausthal-Zellerfeld and Goslar, weeks run in a forested low mountain region with well marked ridge paths. The Bavarian Forest rounds out the picture in the south-east with dense woods and quiet valleys reaching to the Czech border. Smaller venues sit in the Rhön between Hesse and Bavaria, in the Fränkische Schweiz north of Bamberg, in the Brandenburg Hoher Fläming or on the Lüneburger Heide. If you prefer Mediterranean weather you can also pick weeks on Mallorca or the Canary Islands; that is a smaller share of the range and usually bookable in winter. Lodgings are deliberately simple. You stay mostly in small guesthouses, hiking lodges or modest country inns with a breakfast room, a shared dining area and a quiet lounge for reading and journaling. Premium wellness hotels are rarely the frame for a fasting hiking week.

When you compare fasting hike weeks, you keep reading about different methods. In practice most weeks work with one of three clearly established lines, with a few milder variants on top for newcomers. Buchinger fasting is the main method. You take in roughly 250 kilocalories per day from vegetable broth, diluted fresh juices and a touch of honey in tea. There is no solid food during the actual fasting days. This method is the most widely trained in Germany and is led by certified fasting leaders, with some weeks additionally supervised by a doctor. Buchinger is the classic choice for a hiking group, because the small energy supply from broth and juice carries the daily route well. Juice fasting is the second line. You drink exclusively freshly pressed or gently extracted juices from fruit and vegetables, plus water and tea. The energy intake is slightly higher than with Buchinger and the taste is more intense, which makes the start easier for some. In hiking weeks, juice fasting is often offered when the daily legs run longer or when the group is mixed between first-time and returning fasters. Basenfasten, alkaline fasting, is the mildest variant and is aimed mainly at first-time fasters or people who do not want to give up solid food completely. You eat vegetables, salads, fruit and smoothies from purely alkaline sources and avoid acid-forming foods such as meat, grain and sugar. This method works particularly well with hiking, because you have enough energy for long legs while still relieving the metabolism. Which line fits you depends on your experience and your physical condition. Talk to the host before booking about prior fasting experience, medication and your level of hiking practice.

The strongest travel season for fasting hikes is spring and autumn. In spring, roughly from early April to mid June, the days are longer, the low mountains stand in fresh green and daytime temperatures sit mostly between 12 and 22 degrees. That is a comfortable range for a fasting group, because you neither sweat nor freeze while walking, both of which happen faster during a fast than usual. In autumn, from mid September to late October, you get clear views, quiet forests and stable weather, often with morning fog in the valley and sun on the ridge. Summer is possible, but hotter days call for early starts and strict drinking discipline. Winter is rarer in the catalogue; a few weeks run around Christmas or in January as a deliberate annual reset, mostly at venues with milder climate. Who the format suits: you are healthy and physically stable, you can hike three to five hours at a moderate pace and you want to set a deliberate pause from daily life for one week. If you have fasted before, you know the rhythm and the typical reactions on the second and third day. First-time fasters are explicitly welcome in most weeks, because a trained fasting leader carries you through the first days. The format is not suitable during pregnancy, while breastfeeding, with marked underweight, with a history of eating disorders, with acute infections or with serious heart or kidney conditions. If you take regular medication, for example for high blood pressure, diabetes or thyroid conditions, clarify with your family doctor before booking whether and how you can fast.
