Palms Book is an exciting side trip for visitors touring the Upper Peninsula. Known as one of Michigan's alluring natural attractions, the park is home to Kitch-iti-kipi or the “Big Spring.” It is Michigan's largest freshwater spring spanning 200-feet across and 40-foot deep. The flow continues throughout the year at a constant 45 degrees Fahrenheit gushing more than 10,000 gallons of water a minute from fissures in the underlying limestone.
By means of an observation raft, visitors are guided to vantage points overlooking fascinating underwater features and fantasies. Ancient tree trunks, lime-encrusted branches, and fat trout can be seen as they slip through crystal waters far below. Clouds of sand kept in constant motion by gushing waters create ever-changing shapes and forms - a challenge to the imagination. The \observation raft and the trail leading to it are ADA accessible.
