Im not sure if you are allowed to drive all the way to observatory but i did, and information abou 4wheel car is just a words, i got there in my mustang. Be careful there's very steep hills, and dangerous turns, keep your speed limit around 15mph, no jokes with life!
And lso at cold months be careful of sliding ice from observatory "roof" and icy roads.

I hope it helps.
