Fly down along the 15 fwy south from Corona. The best blooms will be on your left side, east side of the 15 fwy. Once you get to Lake Elsinore, big lake on your right, watch out for the parachute jump zone on the south side of the lake. Might as well go a few extra miles and hit the cafe at French Valley, F70. It's good. I don't recommend driving there (the flower fields) over the weekend. They close the freeway off ramp (Lake St.). It gets crazy and they will charge you to take a shuttle in. During the week, you can drive right up to them. I am more blown away at the crowds that come to see them, than the flowers themselves. If you go walking through them, careful of the rattlesnakes. They're waking up right about now.
