Serpent Mound State Memorial preserves an ancient Native American effigy mound shaped like a serpent, attracting visitors for its archaeological significance and scenic hilltop views.
Located in Adams County, Ohio, Serpent Mound State Memorial protects one of the nation's most remarkable prehistoric effigy mounds. The mound stretches over 1,300 feet in length and coils in the shape of an uncoiling snake, with a spiral-shaped tail. Constructed around 1,000 BCE by indigenous cultures, possibly the Adena or Fort Ancient peoples, it is a unique example of earthwork artistry tied to ancient ceremonial and astronomical practices. The site rests atop a plateau overlooking Brush Creek valley, providing panoramic views of the surrounding rolling hills and woodlands. Its landscape consists primarily of oak-hickory forest, supporting diverse wildlife including deer, birds, and small mammals. Visitors can explore a paved walking trail encircling the mound, interpretive signage detailing its history and significance, and a modern observation platform. The memorial includes a museum with archaeological exhibits and educational displays that enhance understanding of Native American history and culture. Outdoor enthusiasts enjoy peaceful hiking, bird watching, and photography opportunities, especially at sunrise or sunset when the mound’s contours are sharply defined. Serpent Mound also hosts seasonal events and cultural programs aimed at preserving Native American heritage. Its unique combination of natural beauty, historical value, and serene atmosphere make it a compelling destination for all ages interested in history, archaeology, and nature.
