PROS:
This site offers amazing sunsets and ocean breezes. There are plenty of facilities, and the camp store is great. The live music is always good, too.
A grocery store is nearby, just over the freeway.
CONS:
It can get very crowded and packed.
Hard to get a site
Many generators are always on.
If you get a site at the far ends, it's a hike to go in and out. Try to get a site closer to the entrance and the store. But you will get a lot of traffic through your site.
Don't try to get there earlier; they usually won't let you in before check-in.
Biking and Running:
Great if you want to ride along PCH. This stretch has good bike lanes that take you into Oceanside or Encinitas.
Good running. You can lap the campsite, which is almost 1 mile, end to end. I usually run down towards Encinitas along PCH.
