Just as Odysseus and his crew started nearing Ithaka, Odysseus had fallen asleep because he had kept watch for nine straight nights and had not slept. When the crew saw that Odysseus had gone to sleep, they had opened the bag that he received from Aiolos hoping they would find gold and silver, but what they found was a hurricane that sent them right back to Aiolos' island.
After Odysseus and his crew left Aiolos' island, they voyaged for six days before reaching the island of the Laistrygonians. When the men realized who dwelled there and what kind of giants they were, the men fled and barely escaped the stones and rocks that the giants threw at them.
The next island the men surfaced on was the island of Aiaia where the witch Kirke subsided on. Kirke welcomed the scouts who Odysseus had sent into her household, but when they started to ease in and start feasting on the food she had brought out for them, she turned the men into pigs.
Odysseus forced Kirke to free his men and she then fell in love with him. After a year, he had to leave and head back to Ithaka so he asked her which way he should go if he were to leave for Ithaka, and she told him he must go to the the cold land of the dead and talk to Teiresias who is the only one that knows the way home.
The Odyssey - Book XI
As the Men approached the barren land, they saw the pit of skeletons of various people and souls wandering about. They made a burnt offering to the Gods and slowly waited for Teiresias' soul to come out, but they were not lucky enough to get him automatically. They had to talk to many souls before him.
