Great Escape from the Crowds
Fly Creek is a great campground that's not far from the city. It's about two miles from the Palomar Observatory. There's a nice trail that goes there form the campground and has good views of the little valley. There are plenty of spots and all of them are shaded. There are a few spots in the back that are even more secluded. There's not a lot of parking for extra vehicles though. The restrooms were clean. The only cell service is about two miles away at the local store. This is where you can buy firewood and supplies.
