At the beginning of September €7 from 8 a.m. to 6 p.m., I think €15 for the whole day including night. Easy to reach, but actually quite unsuitable for an overnight stay

Impossible place - sloping eroded scree slope - we drove on .....

rough and sloping ground, convenient for visiting the center. Paid only during periods when the lifts are in operation, practically after mid-September it was free.
