Stavo pensando di realizzare un sentiero lastricato di roccia qui in Finlandia. Sarebbe un dolce pendio lungo 20 m che fungerebbe da ingresso alla mia proprietà.
Una grossa fetta del mio appezzamento era terreno agricolo, quindi hanno spostato la maggior parte delle rocce nella parte anteriore, il che mi dà accesso a troppe rocce in un paese che preferisce il metallo, aggiungiamo che non mi piacciono per niente i sentieri di ghiaia e ci siamo. Ma, poiché non ho visto sentieri di roccia qui intorno ed essere il primo a fare qualcosa significa che sei un genio o quasi sicuramente stai per fare qualcosa di veramente stupido, ho deciso di chiedere prima qui.
Ci sono altri contro oltre al fatto che è più scivoloso quando è ghiacciato? Si rovinano con la dilatazione congelata? Ho più tempo che buonsenso?

It’s your land. Do what ever you want.
I bet that the rocks that you have have no flat side like the rocks in your pic.
if you have the right rocks for it, i don’t see why not. besides them getting icy and slippery but i’m sure you could work around that.
As a professional rock path builder (I’ve constructed one rock path in a professional capacity.) I can offer some advice.
You’ll need flat rocks and a little bit of drainage to avoid ground frost from messing up your road. Depends a bit on what kind of ground you are building on, but most of the time you’ll want some sepeli on the bottom, sand on top of that, some nice flat stones, and some rock ash to fill in the gaps. You basically want to make sure that water will not stay between the stones and will instead run off on the surface, or seep trough to the ground past the level of the bottom of the stones. If there’s water between the rocks when the ground starts freezing the expanding ice will mess up your road by pushing the rocks up. The bottom layer of sepeli is sometimes optional depending on how good the natural drainage is and how much of you spring you want to spend fixing it up.
So you can build a rock road, but most of the time it’s not worth the effort. If you don’t have nice flat stones, then just don’t. If the stones you have are anything like I imagine them to be, you’d probably save money, time, and effort by just buying more suitable stones.
Even when you do it right, winter eventually finds a way. I’ve redone (set all stones on) my stone path about eight times.
As ThePhotoOne mentioned, due to ground freezing, making a rock path in most types of ground here is a such a major effort, that people usually go with pavement stones on the same go.
You will be spending most of the time on doing the substrate for the path. So do take that into account.
On the left, you can see the rock these flagstones were made of. That kind of sandstone doesn’t exist here. You can find Alta region flat paving stones at a hardware store or a flooring supplier.
[Here’s](https://www.suomela.fi/pihakivetys/) a quite down to earth explanation (in finnish) about how to fight against ground freeze. Google translate seems to do ok job with it. Skimp from these and be prepared to repair your pavings every year.
Lots of good comments here, To answer your question, I think it’s just a matter of making good drainage below the rocks and having the expectation of doing periodic maintenance due to frost heave. I have lots of rocks I use for landscaping, mostly for garden barriers but am also toying with doing some stone paths. There are some youtube videos of landscapers that do this type of work in places like New England which have similar winters, I recommend checking them out.
Also, the local landscaping stores have pallets of flat rock (black, gray and white I’ve seen) for paths like this picture. Unless you’re determined to use your rock, it would be much easier probably to just buy a pallet or two of uniform flat pieces specifically for use of pathways (no need to adjust the substrate for the big differences in rock size for example). Also, I’m always amazed at how fast my rock goes when I start using it. I have a big pile, but I know it would only make like 1/4 of the path in your picture, which doesn’t get me very far… Anyway I love the rock in Finland! Such good landscaping material.
