This preserve is located between Sandwich and Somonauk. Acquired as the very first forest preserve in 1939. Sannauk was long ago the Somonauk Golf Course until the early 1930’s and some of the old greens, sand traps and tee areas can still be seen in the forest. The woodlands, especially along Somonauk Creek, are diverse in structure and have one of the very best displays of spring flora. Skunk Cabbage, Turtlehead, Turk’s Cap Lilies and a host of other uncommon lowland plants abound. The district’s largest stand of Sycamore trees grow in Sannauk and, while not native to this region, Bald Cypress seedlings were planted in the early 1970’s along the lower road. Sannauk has three enclosed and two open-air picnic shelters, hiking trails, a playground, a sledding hill, and fishing along Somonauk Creek. There is an historical marker at Sannauk showing the original Illinois and Wisconsin boundary going right through Sannauk Forest Preserve. The 1 and ½ mile limestone Somonauk Trail, connects the Village of Somonauk ,the Somonauk Library ) to Sannauk Forest Preserve.
