Discernment needs time and it needs quiet, and most of life offers neither. A walking pilgrimage gives both by default: five or six days on the Camino from Sarria is long enough that the question you brought starts to answer itself somewhere around the third afternoon. Medjugorje gives it differently, through a parish rhythm of Rosary, Mass and adoration that fills the evening and leaves the day open. Assisi gives it through two saints who made the hardest decisions of their lives in that one small town.
Rome belongs here too, for a different reason. Seminarians, religious and young couples have been going to the tomb of St. Peter to ask for direction for as long as there has been a tomb. St. Ignatius wrote the Church's great method of discernment in a cave at Manresa and is buried a few minutes from the Pantheon.
A Bold Pilgrim priest-chaplain is on every departure and has time to talk. He will not tell you what God wants of you. He will help you listen.
