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 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.
