Rangers are now permitted to use drones fitted with thermal imaging cameras in the Allgäu High Mountains Nature Reserve: there is said to have been a sharp rise in wild camping with tents and motorhomes in the area.
Cycling until the sun goes down: bikepacking and gravel overnight trips are all the rage right now. Unfortunately, some people are even rolling out their sleeping bags in nature reserves – which is, of course, a no-go. Rangers in the Allgäu are therefore now taking drastic measures.

It’s unlikely I’ll get caught if I simply pitch my tent here in this remote mountain forest. That’s probably what quite a few gravel cyclists might think, too. Unless a forester or hunter happens to come along, that might well be the case. However, in the designated ‘Allgäu High Alps’ nature reserve, the number of people staying overnight appears to have risen so sharply that the authorities have been forced to take drastic measures. With immediate effect, rangers there are deploying autonomous drones equipped with thermal imaging cameras to track down illegal campers in tents, as well as those in motorhomes (in hikers’ car parks). This allows fire pits, as well as people, to be detected on screen even in the densest undergrowth. And that can prove costly: a fine of up to 600 euros is imposed for an unauthorised overnight stay in the nature reserve.

Why? In nature reserves, even straying from the paths is prohibited. Park rangers report incidents of “vandalism” in the form of illegal campfires – which are highly dangerous during the dry season – broken branches, damage to wildlife and litter left behind. Furthermore, wildlife is frequently disturbed during the breeding season. In the Karwendel Nature Park, too, typical “Insta-hotspots” have been appearing for some time now. However, rather than relying on drones fitted with thermal imaging cameras, the park authorities are currently using social media: if a camping photo is posted there along with the location, the rangers know where they need to step up patrols over the coming weeks to prevent the next dangerous campfire.

When is camping in the great outdoors permitted?

Wild camping is generally prohibited in Germany, as it is almost everywhere in Europe. The only exception is ‘emergency bivouacking’ with a sleeping bag, sleeping mat and emergency blanket, or even just a simple tarp. In detail, this means: ‘Spending an unplanned night outdoors to protect one’s own life and health in an emergency situation.’ Such emergency situations may include:

  • As night falls: You’ve misjudged the situation on a tour and, for example, the descent into the valley would be too risky without sufficient light.
  • Change in the weather: Sudden thunderstorms, gales, fog, a sudden drop in temperature, mudslides or heavy rain make it impossible to continue the journey.
  • Exhaustion or injury: You no longer have the physical strength, or an accident forces you to stop.

It is also permitted to spend the night in the forest at officially designated trekking camps. Almost every low mountain range in Germany now offers such small sites in the forest. They are usually large enough for four to five tents, with a fire pit, firewood provided and a composting toilet. You can book these sites online for a single night and, for a small fee (approx. 5–15 euros), receive the GPS coordinates of the respective locations.

In the wild, the code of conduct is: ‘Leave no Trace’:

  • Never leave rubbish behind: not even banana skins! European soil microbes find it harder to break down exotic material.
  • Relieving yourself in the woods: Experts carry a small spade with them to bury their waste. Toilet paper should be taken away and disposed of in the nearest dog waste bin.
  • Washing and washing up: use no soap whatsoever. Even biodegradable soap without synthetic ingredients harms micro-organisms in lakes and streams.
  • Forest fires: Only at officially designated fire pits, and even then not after a prolonged dry spell.
  • Respect the flora and fauna: do not set traps in areas where wildlife is known to pass (look out for animal tracks and droppings on the ground) and do not damage plants unnecessarily.
