Tennis courts in Seneca are one of the best in the country. There are usually four main types of courts depending on the materials used for the court surface; clay, hard, grass and carpet courts. Each playing surface has its own characteristics which affect the playing style of the game. Clay courts slow down the ball and produce a high bounce; grass courts are the fastest type of courts in common use, though high-maintenance; hard courts vary in speed, they are faster than clay courts but not as fast as grass; carpet is a tennis term for any removable court covering. A north/south orientation of outdoor courts prevents background glare at dawn or dusk.
