If you drive during rush hour time it can easily take 3 hours. If you drive before moring rush or in the late evening then it will take about 1:15. It all depends upon accidents, road construction, etc. The easiest way to get there from Anaheim (
Disneyland area) is the I-5 North to the 118 West. Exit at Madera Road and drive approx. 2 miles to Presidential Lane. Stay away from going on the 101 if at all possible because that freeway can be murder to drive.
