Alta Lake State Park

North Cascades

Just outside the small town of Pateros, Alta Lake State Park is a state park that embodies the spirit of Eastern Washington. Donated to Pateros by a jeweler from Wilbur, he was mining in the area and laid claim to the land nearby as well as the lake. When he realized the lake was unnamed, he dubbed it Alta Lake, after his daughter, Alta Heinz.

Ponderosa pine abound on the shores of the lake, while 2 miles of trails allow for wandering visitors to enjoy the area.

Two miles long and half a mile wide, Alta Lake is popular among anglers and windsurfers during the summer months. Campers can spend a weekend here wandering the grounds, swimming in the lake, or sunning themselves on the shores.

In 2014, the state park was damaged by the Carlton Complex fires, and in 2016, a WTA youth volunteer crew stepped in to help repair the trails and lands owned by the park.
