Ayers Sand Prairie State Nature PreserveTucked just south of Savanna, Ayers Sand Prairie Nature Preserve offers a rare glimpse into one of Illinois’ most unique landscapes. This 100+ acre preserve protects a high-quality dry sand prairie ecosystem shaped by ancient glacial activity, where rolling sand dunes and open prairie create a striking, wide-open setting. Visitors will find a surprisingly diverse mix of plant life, including native grasses like little bluestem and June grass, along with seasonal wildflowers such as puccoon and sand primrose that bring bursts of color throughout the year. Wildlife is equally impressive, with grassland birds, small mammals, and reptiles all adapted to this dry, sandy environment. Designated as one of Illinois’ early nature preserves in 1974, the site remains largely undeveloped, offering a quiet, back-to-basics outdoor experience ideal for hiking, birdwatching, and photography. With minimal signage and a simple roadside access point, Ayers Sand Prairie feels like a true hidden landscape—perfect for visitors looking to explore something a little off the beaten path. DIRECTIONS: From Savanna at the junction Hwys. 52 & 84, take Hwy. 84 south 2.7 miles to Airport Road, then turn and go east 0.5 mile. The nature preserve is north of the road.
