Mazda Raceway Laguna Seca is an auto racing course built in the 1950s near Monterey, California.
The racetrack is 2.238 miles in length (3.58 kilometers), and has 11 turns, including the famous (and gut-wrenching) Corkscrew at turn 8. Many of the turns are bordered by wide swaths of sand to prevent disaster when cars miss the turn.
A variety of racing and exhibition events are held at the raceway, from superkarts to American Le Mans racing to car shows.
The track is featured in video games, most notably the Gran Turismo series.
There are camping facilities located at the raceway, which are used year-round as part of the Laguna Seca Recreation Area, the county park in which the racetrack is set.
The raceway's primary corporate sponsor is Mazda, who hold some of their own events there and display their products at major racing events.
Also at Laguna Seca is a branch of the Skip Barber Racing School.
Major events each year include a Champ Car World Series weekend, a four-hour endurance race for the ALMS and starting in 2005 the MotoGP United States Grand Prix.
