Chris and Mo,
Thanks for your welcome.
Chris,
For now, the situation is acceptable for 4x4 drivers.
The restrictions exists in two modes:
1. The classification of the local where you are driving and restrictions involved;
2. The months of July, August and September.
For the 1. we have a link with all the parks and legislation about:

The 2. tells you that for tracks with a special road sign on the entrance, you should not use that track on those three summer months, because there are many trees and also risk of fire. If the mountains have no trees (a great part) there is no restriction.
Mo,
Living here I am “doubtful”, but this country has on its little area a great variety of lands: Mountains, planes, “green”, arid, seaside, humid clima, dry one. Yes, I believe it is a good place for a travelling holiday.
Cheers
