Inland City (Japanese: クガシティ Kuga City) is the largest port city on Blue Point Isle. Located on the southern end of the island, it is known as the entry point to the Whirl Islands. Pokémon Trainers can register for the Whirl Cup here. Off the shore of Inland City is the large blue rock from which Blue Point Isle takes its name. The Pokémon Center here has a large pool that connects to the sea.
