You are walking through a forest, which fork should you take?

You are walking though a forest when you reach a fork. One path leads to the next town a comfortable bed and food and drink. The other leads to a desolate wilderness with no water or life of any king. Two Brothers are stood by the side of the side of the road. One will always tell the truth and one will always lie,but you don't know which is which. What question should you ask to get to the town?
