This type of enviromental tourism is actually my favourite type of tourism and I think in a few years, with overpopulation it will be the most demanded type (peaople will want more peaceful places). I actually go every summer to a place in the inetrior of Portugal called Gerês, and it is the most wonderful thing! Really recommend it and I'll probably do a post on it!
btw, thanks for the 1,50 likes mate!! Means a lot for a noob like me 😄
