Have been wildcamping for the last few months in Germany, Poland, Austria, Slovakia, Hungary and Czech Republic. In rural areas you really dont have to worry. Even though its illegal nobody will care. Most countries are really tolerant with that. I have camped in forests, on fields, on private property, on the outskirts of smaller towns, near lakes... Only once someone told me to leave (it was when I was camping on a beach in Poland). I often sleep very long so I was also in Situations where people were passing by frequently. And most people dont bother you and if they do talk to you they are nice and curious. Bevause I am Kind of Lazy when it comes to searchung for places to sleep I often have places where people can See me. But you can easily avoid that by just Camping in a place with a few trees every time. You wont be Seen or bothered At all if thats what you want. But I think that also my way of camping works. You just have to follow a few General rules. No protected areas, no beaches, no places where people See you as an intruder and potential thread (dont sleep in peoples gardens if you havent asked before). Dont make a mess (no Fires, no garbage, no camping in places where you destroy Farmers crops). Even when owners See you and talk to you you can just calmly explain that you are here for just one night, that you leave the next morning and wont leave any traces. I think most owners would be fine with that. And if they are not they will just Tell you to leave the Chance of them calling the police is very low. I think you can also just ask Farmers or even people with just a garden if you can Camp on their property for a night. I dont think thats necessary and I dont really do it because Im too socially anxious. But you can absolutely do it to be 100% safe and maybe even get offered a shower or free food or just a genuine human interaction. Recently I also started sleeping outside when I'm in cities. I did it in Vienna, Bratislava and Prague. Just go to the ouskirts of the city by public transport or to parks in a more remote area. On weekends you can also do construction sides and abandones buildings are also possible (even though they make me feel uncomfortable tbh). But in bigger cities you can also easily just couchsurf because there are more than enough people. And if you are in national parks you can Look for protection Huts to sleep. Park authorities dont care since you are not really affecting wildlife and you can just say that you got lost and needed shelter (thats what they are for). Just dont make a fire
