There is so much wilderness out there. Completely free to access. Well you are not really supposed to camp in the wild in many countries but who cares? For those willing to brave it out there I highly recommend you get a nice hammock. The camping experience goes up no end. Not only does it solve the issue of not find soft, flat ground in the wild but it reduces the amount you have to carry. No inflatable mattress or tent. Just a hammock and a lightweight tarp. After a bit of practice, putting them up and taking them down takes minutes. You can get a wonderful nights sleep.
You need a tarp really. The type is called a basha tarp which are made from very light material so not like the thick ones you might get from a DIY shop. You can then run a ridgeline between the two trees you are hammocking off and put the tarp over it. The one I’ve got is a DD tarp. I think it’s 4x3 metres. If being honest it’s bigger than what you really need but it cost not much more than the smaller one so went for it.
That sounds pretty fun, I’d love to try it out bc I live near quite a few different campout spots
