Where is Baramos in Dragon Quest IX?

Answer 1

If you DON'T have the map, head to the island north of Swinedimples and go inside the cave. There should be a skeleton inside.

If you do have the map, consult an online guide - the grotto itself is in a different location for every player, so you'll need to look at the 17 maps on the related link until you see the location that your specific Baramos map is showing.

Answer 2

He is in a grotto. The map you use is called Baramos Map, which you obtain by riding the Starflight Express to the island on Cringle Coast, and completing a quest given by a skeleton. The actual location of the grotto is completely randomised, like all other grottoes.
