Intergalactic travel is space travel between galaxies. Due to the enormous distances between the Milky Way and even its closest neighbors, any such venture would be far more technologically demanding than interstellar travel. Intergalactic distances are roughly one-million fold (six orders of magnitude) greater than their interstellar counterparts. The technology required to travel between galaxies in a feasible way and within a human lifetime is far beyond man's present capabilities, and is currently only the subject of speculation, hypothesis, and science fiction.

“You are wonderful. I love and honor you.... [ellipsis in source] Lead your own life, attend to your charities, cultivate yourself, travel when you wish, bring up the children, run your house. I’ll give you all the freedom you wish and all the money I can but—leave me my business and politics.”
