A German car collector is making the journey in a vehicle that once belonged to the pontiff himself -- now spruced up and with the licence plate IL JP2H, the H standing for the German for saint.
In the Philippines, Asia's Catholic outpost, hundreds have turned out to kiss his relics, including hair strands, bloodstained clothing and a cassock, on exhibit at various venues there over the coming months.
"I am so happy. I am ready to die now that I have seen his relics," retired grade school teacher Gene Suarez, 67, told AFP at a Manila chapel.
In Ireland, pope-themed items are going fast at shops linked to the country's top Roman Catholic shrine in Knock, which John Paul II visited a year into his papacy in 1979.
"People (are) coming along again looking for items related to him, be that a picture, a relic, a prayer card or whatever," said Peg Carmody, manager of the Knock Shrine Souvenir Shop.
Though Ireland is no longer as staunchly Catholic, the doctrinal conservative's influence is still felt, according to Father John Harris, editor of a new book celebrating his sainthood.

The first non-Italian pope in more than 400 years and the first from eastern Europe, John Paul II was a source of strength and hope for Poles, who credit him with helping topple Communism.
"He was made pope at a particular moment in time, probably the best possible moment in history for us to have gotten him," said Katarzyna Uklanska, a Warsaw sociology student who wrote her doctorate thesis on the pontiff's posthumous role.
That view of him as political player is shared by other ex-Soviet states in the region including Slovakia, where the avid sportsman enjoyed hiking and is considered "the most popular pope" according to Slovak religion expert Imrich Gazda.
"Given the long term he served, many generations still view him as THE pope," added Slovak Bishops Conference spokesman Jozef Kovacik.
John Paul II will be remembered for eschewing the pomp that surrounded his predecessors and seeking contact with ordinary people, be they Communists or Jews or Catholics, even paying a prison visit to the Turk who tried to assassinate him in 1981.
"Throughout his whole life he displayed that humanity in such a way that even nonbelievers considered him a wonderful person," said Halina Marciniak, an educator and head of a group of nearly 1,300 Polish schools that carry his name.
"And what he preached moved everyone... That kind of person doesn't come along very often. That's why I think his cult following will endure."
