California requires licenses (~$110) and tags ($12 ea./one per animal) to hunt hogs; there is no limit. There are plenty of them, but as with Texas most of them are on private, pay-to-play land. There are public opportunities, but from what I understand they are quite challenging, with very low success rates.
Texas has, in my opinion, better oppurtunities at lower cost, particularly if you want a javelina. Sure, most places are fenced, but true hog-proofing is expensive and pretty rare, at least in my experience. Besides, a hog's home range can be pretty small if the habitat is good, so if you're hunting 10,000 fenced acres, the hogs are free-ranging for all intents and purposes. A pig in the middle of that may never even know there is a fence.
Texans bait their pigs, shoot 'em at feeders, shot 'em by moonlight (my personal favorite) or spotlight, run 'em with dogs, knife 'em, etc. You name, you can probably do it down there. You can find prices from $100-250 per day, all inclusive, with varying limits of hogs and other exotic game. Just type in "hog hunting Texas" in

Pig hunting is one of my favorite pasttimes. Hopefully you find a good option and get to partake of it.
