Although I don't like to, I have to comment. You're right SIMONZOR, but only up to where you mention preserving the alpine environment.
What do you have for preserving the alpine environment?? That they bulldozed the ground, opened a new wound somewhere for gravel digging which they piled for this so-called parking. Where are the oil traps then, all water from the so-called parking flows ....WHERE??
What about safety? Park at your own risk! Yeah, why if I pay! In KClj the parking is covered, under cameras and for the first half hour the price is different.
What do quads do in TNP, what are the trails like, what happens on Velika Planina?
I'm for strict environment protection, just not in this way: barrier, price, cashier threatening with police, when you ask her what this area offers tourists she gapes as if you fell from space
