I'm not sure what you mean by 'can't break threw the caves and breed winter dragons with island dragons'...

But if you're on ios, then you can breed a Winter Dragon with a Purple type and get the Ice Age Dragon, thus unlocking the Arctic Isles.

You can't breed Arctic Isles dragons if you're on Android, however...
