An extension of Route 4 and ironically caled a "resort". If anything it's more troublesome than the route. It's easy to get turned around in the dunes and become dehydrated, leaving you for dead in the shifting sands.
The sand filled ruins of what once was a magnificent castle lies within the heart of the Desert Resort. Legend has it that one of the heroes of legends built this structure. Deep in the lowest depths is said to be the chamber of Volcarona, a Pokémon that stood in place of the sun. Which means it's very deadly. Oh yes, and be catious not to get buried down there.
