Stay on the 10 to the 405. That s the most direct. May not be the fastest, but definitely the most direct.Personally, I d take the 210. It changes numbers a couple times (134, 101), but it s the same strip of freeway that keeps going west. Then you take the 405 south to UCLA. Just my personal preference.
Keeping it simple, take the 10 to the 405 north, then exit the 405 in a few miles at Wilshire Blvd East (Just BEFORE the big VA hospital and cemetery)......go east several blocks, then any street you take going north will put you in the UCLA vicinity....Plan where and how you are going to park NOW, those campus cop guys are NATZI.....
google or yahoo map the directions.. easy as 1 2 3actually, they are very accurate as far as directions go.
