Many visits to Poland include only Łagiewniki, often as part of a day from central Kraków together with the neighboring Sanctuary of St. John Paul II. That is a real Divine Mercy pilgrimage in itself if the time there is unhurried. Warsaw also has a place in the story: Faustina entered the congregation at its convent on Żytnia Street in 1925.

The distances decide the rest. Warsaw is roughly 290 km (180 miles) north of Kraków, and Płock about 110 km (70 miles) northwest of Warsaw, so Płock and the birthplace villages in central Poland fit a journey that already passes through Warsaw. Vilnius is another 460 km (285 miles) or so northeast of Warsaw, in a different country, with Białystok on the way; from Kraków it is about 750 km (470 miles). Adding it turns a Kraków pilgrimage into a route of several more days.

Good to know before you go: the sisters in Płock have been raising a new shrine church on the site of the 1931 vision, so ask them what is open before you build a day around it. Decide first what you want to pray for, then how many places you can visit without rushing.
