Where did Perseus go step by step to find Medusa?

Perseus began his journey by visiting the Graeae, three sisters who shared one eye and one tooth, to obtain information about Medusa's location. After learning that he needed to find the Nymphs of the West, he traveled to their dwelling, where he received magical items including winged sandals, a reflective shield, and a helmet of invisibility. Equipped with these tools, Perseus then ventured to the Gorgon’s lair, where he ultimately confronted and beheaded Medusa.
