The Den is an Arnold Palmer-designed 18-hole course located in central Illinois in McLean County. The Scottish Links-style 6,900-yard course, which opened in 1997, rates a 72.9 with a 128 slope. Wild prairie grasses used in the rough compliment wide bentgrass fairways featuring over 130 bunkers and sand traps. Water is involved in half of the holes. Ancillary features include a large practice putting green, a practice chipping green (with practice bunker) and a large driving range with several target greens.
