Choose by what you are carrying and what you can manage physically. For serious illness or disability, Lourdes has the most developed help, and immersion in the baths is offered there again: the Sanctuary's 2026 press kit says the baths are once more given over to immersion, and its water page says sick and able-bodied pilgrims alike are welcome, with no booking needed for individuals, in a season it gives as April to November (checked October 10, 2026). Pilgrims who prefer not to be immersed can make the simpler water gesture, drinking the spring water and washing the face.
For a wound that is interior, such as guilt or the need to forgive, many pilgrims choose a place known for Confession and mercy: the Divine Mercy Sanctuary in Kraków, or Medjugorje, where the Holy See's 2024 nihil obstat permits pilgrimage and recognizes spiritual fruits without declaring the reported apparitions supernatural.
Be cautious with claims: reports of healings at any shrine are personal testimony unless the Church has examined and recognized them, and popular customs involving water, oil or earth are signs of prayer, not remedies. The Church's own sacrament for the sick is the Anointing of the Sick, which the Catechism says "is not a sacrament for those only who are at the point of death" and which only a priest or bishop can give (CCC 1514, 1516); ask the shrine, or your own parish priest, about it before you travel. A shrine near home is a legitimate choice.
