Lake Pleasant Regional Park is a large outdoors recreation area straddling the Maricopa and Yavapai county border northwest of Phoenix, Arizona. The park covers a total of over 23,000 acres (93 km²) of mountainous desert landscape, including the lake, and boasts a number of other recreational activities, such as mountain biking, camping, and hiking. The park also has an educational visitors' center that provides information regarding the history of the lake, the construction of the Waddell Dam and the surrounding areas. The lake itself is used as a major water sports recreation center for the Phoenix metro area, as well as serving as an important storage reservoir for the rapidly growing region. A number of boat docks and beach access make the lake a popular destination for scuba diving, water skiing, jet skiing, sailing, windsurfing and other water sports. The presence of the lake has also attracted other recreational activities in the area, such as a dirt racetrack and a large glider school/airport.
