Ski pass and Parking Sierra Nevada spain

I am coming ski ing independently in the Sierra Nevada. I have been told that a ski pass has to be booked through your holiday rep. How do I go about getting one. Also where is the best place to park as I have seen on the internet that prices up to 40 euro..

Contact the local tourist board and you should be able to book your lift passes through them, check out the link :D
