Pouvez-vous me dire comment aller à la gare la plus proche?

Pronunciation: Poo-vay-voo muh deer koh-mahn tuh-lay ah lah gahr lah ploo prohsh?

Meaning: Can you tell me how to get to the nearest train station?

This polite question is essential when traveling in French-speaking countries; using the conditional "Pouvez-vous" shows respect and is more natural than a direct imperative.
