Palms Book State Park is a 388-acre public nature preserve within Thompson Township in Michigan's Upper Peninsula, originally established in 1926 by John I. Bellaire and stocked with visitor amenities during the 1930s as part of a development project by the Civilian Conservation Corps. The park is the site of the Upper Peninsula's famed Kitch-iti-kipi "Big Spring," the state's largest freshwater spring, which runs 40 feet deep and gushes more than 10,000 gallons per minute. Self-operated observation rafting opportunities are offered for up-close exploration of the spring, showcasing giant trout within the spring's waters.
