camping abroad holidays

How old do you have to be to go on holiday?
I am 15 and live in the uk. I want to go away with my friend (same age) on holiday but not abroad, somewhere in england. We just want to go to a holiday camp and stay in a caravan or something simple like that. How old do you have to be in the UK to do this?
Thanks in advance
As mentioned in your other question, it’s highly doubtful that you would get into any caravan or camping site at 15 or 16….but you could try Youth Hosteling…
