Alta Lake State Park is a 181-acre (73 ha) Washington state park located in the mountainous northwest interior of the state. The park and adjacent lake lie beneath towering stone cliffs, formed by glaciation, that rise 1000 feet (304 m) above the valley floor, and carry on up to the top of Old Goat Mountain which sits 4200 ft (1280 m) above the park. The lake is about 2 miles (3.2 km) long and .5 miles wide. The park has 2 miles (3.2 km) of hiking trails. Popular activities at the park are sailboarding and golf at the nearby Alta Lake Golf Course. Although quite small, this park is a very popular summer camping location.
