Slateport City (Japanese: カイナシティKaina City) is a city on the southern coast of Hoenn. A market formed because of the abundance of food and clean water in the area. It soon blossomed into a harbor with a lighthouse in the south that lights the way for ships passing and coming into the harbor.
There are three entrances to Slateport City, the northern entrance being Route 110. The southern entrance being Route 134, and to the east is Route 109.
