If you are lucky enough to take a trip to Israel, try to stop at Qasr el Yahud, the place that is most likely the exact spot where Jesus baptized John the Baptist. Unfortunately, this site is now in the middle of an international border, so churches only venture there on special feast days, however, the government opened up a site at Yardenit by the Sea of Galilee for group baptisms.
Matthew Chapter 3:13-17
13 Then Jesus came from Galilee to the Jordan to John, to be baptized by him. 14 John would have prevented him, saying, "I need to be baptized by you, and do you come to me?" 15 But Jesus answered him, "Let it be so now; for thus it is fitting for us to fulfill all righteousness." Then he consented. 16 And when Jesus was baptized, he went up immediately from the water, and behold, the heavens were opened and he saw the Spirit of God descending like a dove, and alighting on him; 17 and lo, a voice from heaven, saying, "This is my beloved Son, with whom I am well pleased."
