The Second Joyful Mystery the Visitation (Of course her spouse Saint Joseph would accompany her to protect her on the long and dangerous journey ^_^):

Luke 1:39-56
And Mary rising up in those days, went into the hill country with haste into a city of Juda. [40] And she entered into the house of Zachary, and saluted Elizabeth.

[41] And it came to pass, that when Elizabeth heard the salutation of Mary, the infant leaped in her womb. And Elizabeth was filled with the Holy Ghost: [42] And she cried out with a loud voice, and said: Blessed art thou among women, and blessed is the fruit of thy womb. [43] And whence is this to me, that the mother of my Lord should come to me? [44] For behold as soon as the voice of thy salutation sounded in my ears, the infant in my womb leaped for joy. [45] And blessed art thou that hast believed, because those things shall be accomplished that were spoken to thee by the Lord.

[46] And Mary said: My soul doth magnify the Lord. [47] And my spirit hath rejoiced in God my Saviour. [48] Because he hath regarded the humility of his handmaid; for behold from henceforth all generations shall call me blessed. [49] Because he that is mighty, hath done great things to me; and holy is his name. [50] And his mercy is from generation unto generations, to them that fear him.

[51] He hath shewed might in his arm: he hath scattered the proud in the conceit of their heart. [52] He hath put down the mighty from their seat, and hath exalted the humble. [53] He hath filled the hungry with good things; and the rich he hath sent empty away. [54] He hath received Israel his servant, being mindful of his mercy: [55] As he spoke to our fathers, to Abraham and to his seed for ever.

[56] And Mary abode with her about three months; and she returned to her own house.
