During the Fourth Age, it was one of the last Elven havens as the remaining Elves of Rivendell and Lothlórien left Middle-earth. In the beginning of the first century, Fourth Age, it experienced a population growth as migrants from the east came to Mithlond. Not all Elves left Middle-earth immediately, many of the migrants made long-term temporary settlements.
Aside from Elves, Gandalf, Bilbo Baggins and Frodo Baggins also went to Valinor from the Grey Havens, and a family tradition held that Samwise Gamgee, having been himself a Ring-bearer, albeit briefly, did likewise, in the year 1482 of the Shire Reckoning, Fourth Age 61. It was also told in the Red Book of Westmarch, that after Aragorn's death Legolas built a grey ship and left Middle-earth to go to Valinor, and that Gimli went with him.
