Where does Circe tell Odysseus to go upon leaving her?

When Odysseus is preparing to leave Circe's island for the first time, she tells him that he must travel to the Underworld in order to seek the guidance of the blind prophet, Teiresias of Thebes, who - - though dead - - still has his mind because Persephone has granted him reason and understanding. He does so and Teiresias tells him what his way home will be like.
