Answers:
Ask them "Which way would your twin tell me to go if I asked him!?"
Then you go in the opposite direction to what the person answers!.
This works because if the person you ask happens to be the liar, he knows that the other person would point you in the right direction, so the liar would point you in the wrong direction!. And if the person you ask is the truth-teller, he knows that the other person would point you in the wrong direction, so he will also point you in the wrong direction!. So in both cases, you are guaranteed to be pointed in the wrong direction, so you go the opposite direction!.
EDIT: Or if you want to be pointed in the right direction, ask "Which way would your twin tell me to go if I were to ask him which is the wrong direction!?"Www@Enter-QA@Com

Yeah - Let's call the correct way 'A' and the other 'B'
Ask either one of them 'If you were the other twin, which way would you say is the correct way!?'
If it's the truth-telling one, he has to tell you that the liar would say B!.
If it's the liar, he would tell you that the other would say B, because he's lying about that!.
So go teh other way to the one which he tells you!.
