How old do you need to be to travel to a european country if you live in europe already?

Question

does anyone know how old you need to b to travel to a european country like spain if you live in england

Answer 1

I think it is 6 weeks old before they allow you in a plane, but if you travel by ferry and car just a day old will do. You need to be accompanied by your parents, or legal guardians to travel when so young.

Oh, you want to know how old you need to be to travel alone?
I think it is either 16 or 18, when 16 you will need a proof of permission of your parents or guardian, and at 18 you are an adult and can do what you want, (within reason.)
If you are younger you will need that same proof, as well as have your parents arrange things like bringing you to the airport and have someone collect you at the other end.

And if you are not yet 18 you might need someone book you a hotel or apartment, but I think you would be alright in a hostel (proof of permission might be needed.)
