The Sky Isles is a location in Grandia: Parallel Trippers. It is the third dungeon visited in the game and can only be traversed by flight of an airship or through a series on cannons that fire the party across the Sky Isles. The Sky Isles Castle is home to the Wyvern who must be defeated in order to obtain the Tower Key. The area lies to the south-west of the Ancient City, is south of the Tree Sea and lies west of the Ghost Land. Milda can be found and recruited in the Sky Isles from the first visit.
