There is only one road up that mountain as well, which was part of the reason, I'm sure.
Look at the TdF Web site, specifically at the timeline for the stage you want to see. It indicates when the caravan goes past, and it has been about an hour before that when the road has been closed in the four years I have been watching.
My personal tips would be:
1. Don't try to go to a one-road climb unless it is the day before (at least).
2. Looking at the timeline, try to approach the course without traveling on the actual course roads. You can usually get a spot a short distance from the course to park, and then walk to the course itself.
3. If you want goodies from the caravan, stand on the passenger's
side of the road, as that is where most of the stuff is distributed.
4. If you want good photo ops, in general get them as they are well into a climb, preferably not the first. They tend to spread out more there, and are going slower. Also scout out a position where the sun will be in their faces when they get there.
5. If you want souveniers like bottles and musette bags, get somewhere just before or just after a feed zone. For musettes it has to be after.
6. Be sure you have sun protection, because it gets very
hot out there.
Lastly, since this is a[nother] historic year, what it being LA's last race and a chance at 7 in a row, everything will probably be worse than other "normal" years. Most of all - have fun!
