Here is a thread full of really useful suggestions. :)
Forearms can be tricky to camouflage, but depending on how your scars look, you can get away with any number of different things to cover or disguise them. If you don't want to wear arm socks or fishnets, you can try temporary or henna tattooing, funky bracelets, a long sleeved top made of some lightweight fabric, or with a funky cutout on the back that lets your skin breathe.
Good luck, and don't let your scars detract from your trip! Have fun. *hugs*
