Alamo Lake State Park is a state park of Arizona, USA, centered on Alamo Lake, a flood control and recreational reservoir. The park is located in western Arizona about 38 miles (61 km) north of Wenden. It is accessed via dirt road off either U.S. Route 60 to the south or U.S. Route 93 to the east. Owing to its remoteness and lack of paved access roads, the park is often considered one of the "best kept secrets" of the state park system.
Alamo Lake State Park features camping facilities and attracts wildlife enthusiasts, as the park is home to numerous wildlife species including the bald eagle. The park's remoteness and distance from cities also makes it a destination for stargazing.
