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.
Nature of the Area
The mountainous terrain that surrounds Alta Lake was formed by glaciation. The native rock is primarily igneous.
History of the Area
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).

Group Accommodations:

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.
There are two boat ramps with 60 feet of dock space. Waterskiing and personal-watercraft use on the lake is restricted to the hours of 9 a.m. to 6 p.m. (Okanogan County safety ordinance).

The park provides one kitchen shelter without electricity, plus two sheltered and 18 unsheltered picnic tables. All day-use facilities are first-come, first-served.
Area Attractions

Sailboarding is also popular with park visitors.

Waterskiing can be dangerous on this small lake. There are waterskiing opportunities four miles away on the Columbia River.

There is an 18-hole golf course in the Alta Lake area.

Horseback riding is allowed at the park.

June 25 Great Family Location by m_cherry
Our first time here, June 2017, great place to camp, has hot showers, a great swimming beach, a little town 2 miles away if you need anything, and fishing was great, mostly bass and trout. Also great start glazing at night.
July 29 Park Ranger Sharon...
...helped us out immensely - especially since it was our first time to the site and we had some campsite confusion. While both professional and kind, her assistance made our trip to Alta Lake excellent.
