Garabandal is a false apparition perhaps:
http://www.unitypublishing.com/Apparitions/Garabandal2.html
The "Virgin" asked that the girls not bring blessed sacramentals [rosaries, crucifixes, etc.], for she wanted to bless them herself. And over the years she is reported to have blessed and kisses hundreds of them. Remember that only blessed sacramentals affect Satan. Keep in mind, that Mary is not a priest. She cannot give a priestly blessing. Never in Her life or in any apparition for two thousand years has Mary given a priestly blessing to anything.
PROPHESY

There are three prophesies in Garabandal: first a world-wide WARNING that everyone will see and feel; second, a MIRACLE at Garabandal that all will see and will remain there forever; and last, the PUNISHMENT. Twenty-five years later, nothing has happened.

But let us look at them. The warning is supposed to be seen and felt by everyone in the world so that we will know our sins and repent. That being the case we have no need to be watchful and keep our lamp burning, since God will warn us in time to repent. A priest, Father Lius Andreu, is reported to have seen a vision of the coming "miracle" but died without any know cause the next day. Conchita said that his body will be found uncorrupt after the "Great Miracle".  His body has since been exposed but he is not uncorrupt.

This is the same trick Satan used in inventing "Rapture". The most important time in our life is "the moment of death". Satan wants us to think we have no reason to fear this moment; therefore, he invents things like the WARNING or the RAPTURE. The Holy Scripture tells us that Chastisements will come like a thief in the night when we least expect them. But if we have a miracle first, there is no need to be watchful.

Last, but not least, all chastisements are conditional. There is no condition in the punishment told of in the Garabandal prophesies.

There are other prophesies. The "Virgin" said that the pope and Padre Pio would see the miracle. Both are dead. She said that there would be only two more popes and that this would be the last one.  Other prophecies make it clear that this is not the last one.
Conchita insists that this is the last pope. However, according to the list of St. Malachi, the next pope will be called the Glory of the Olives. Should we believe Conchita or a saint. In fact the last Holy Father will be named "Peter". Don Bosco prophesied that a Holy Father would die during a great chastisement and a new one would quickly replace him. That has not happened yet. There was also a miracle promised on October 18th of 1961. Nothing happened. And they were told this is the last warning to be given to the world.

OK this website is perhaps NO but it doesn't make Garabandal true.

Malachi Martin also believed in Garabandal.
