A permit maybe required. Contact USFS Los Padres
Prices varies and you can pitch tenant anywhere where space is available
Get your Wilderness Pass and you can camp in any site that you like including pinching tents or 10 trailers and Etc. It's All About That Bass. The only time you need to pay is when they have bathroom facilities that will be an extra charge I recommend the fish bowls if you are a hiker it's a great memorable hike along with many others
I assume that you can as there are a numerous campgrounds in the Padres Forest are you have to get a Wilderness Pass also or I forget what it's called but you can buy them at any of the stores around this area I do not know if there's an additional fee to pitch your tent I think you just need the Wilderness Pass
You can pitch a tent anywhere, however, reservations are recommended, price will change from location to location, please check the website for more information and details.
There is primitive camping in a couple of areas. Not sure on cost.
