Alta Lake State Park is a 181-acre camping park where the mountainous pine forests meet the desert. Alta Lake is about two miles long and a half mile wide. The park offers good trout fishing during summer months. Lake Chelan, with its many activities, is 30 minutes away.

The mountainous terrain that surrounds Alta Lake was formed by glaciation. The native rock is primarily igneous.

The Alta Lake area was given to State Parks by the city of Pateros and was established "Alta Lake State Park" in 1951. The lake was named "Alta" in 1900 by Mr. Heinz, a jeweler from Wilbur, who was mining in the area. Finding the lake without a name, he called it after his daughter, Alta Heinz

The park has 91 tent spaces, 32 utility spaces, four restrooms (one ADA) and 12 showers. Maximum site length is 38 feet (limited availability).

The park offers two group camps. The Wooded Group Camp accommodates a minimum of 15 guests, maximum of 45. The Field Group Camp accommodates a minimum of 20 guests, maximum of 85. RVs are allowed, but there are no RV hookups. Fees vary with size of the group.
