Keyhole is a mecca for both resident and migrating birds of all species. Visitors also have the opportunity to enjoy a variety of other wildlife, including mule deer, pronghorn antelope and wild turkeys. There is a marina located on the headquarters side of the lake and operated by a concessionaire. The concessionaire has pop, alcohol, groceries, bait, tackle, fishing licenses and 10 electric campsites that he reserves. There is a public boat ramp at the marina.
Keyhole State Park is open year around and offers nine campgrounds that are all overlooking the lake. There are more than 170 sites with tables and grills. Most of the sites will handle large R.V.'s and trailers. Tent or R.V. camping is possible at all sites. Some of the sites are in the trees and some are out in the open. Services are discontinued at the following areas on September 30: Homestead, Cottonwood, Rocky Point, Pronghorn, Pat's Point, Arch Rock, Wind Creek, and Coulter Bay. Trash recepticals and restrooms are still available. The roads to Coulter Bay, Wind Creek, the marina, and Pat's Point are plowed in the winter.
