A Catholic pilgrimage is a journey to a sacred place undertaken for spiritual purposes. Pilgrims may go to pray, attend Mass, receive the sacraments, give thanks, or visit places associated with Jesus, Mary, the Apostles, and the saints. The Catechism of the Catholic Church (paragraph 2691) describes pilgrimages as evoking our earthly journey toward heaven and as occasions for renewal in prayer. The intention matters more than the distance traveled.
The best-known Catholic destinations are Rome, the Holy Land, Santiago de Compostela, Lourdes, Fátima, and Guadalupe. Some have formal rules: the Compostela certificate at Santiago, for example, requires at least the last 100 km on foot, with a stamped pilgrim credential.
A local shrine can also be a pilgrimage destination. You do not need an international flight or an organized tour to make a meaningful journey.
