Summer Island is the third seasonal island that the Protagonist of Rune Factory: Tides of Destiny can unlock. It is possible, with the help of a Spirit Wand and monsters, to grow crops and trees here, just like Spring Island and Fall Island. It is found in the southwest section of the Fenith Sea, in the intersection of the two great currents.
No hostile monsters are found here.
Summer Island is an island that resembles a beach, and a typical summer paradise. It has the Large tree at the northern section and smaller islands at the south. One can fish from the shallow water separating the small landmasses and catch many summer fish.
The request to find this island is given by Sierra, who wants to find a summer paradise in the sea.
The Player can grow Summer crops here in order to cook materials, sell, or give to some eligible bachelorettes/bachelors that might like the harvest.
