Big Bone Lick State Historic Site Autumn Bison Viewing & Family Fossil Trail

About this adventure

Celebrated as the 'Birthplace of American Vertebrate Paleontology', Big Bone Lick State Historic Site in Union, Kentucky, offers an unforgettable prehistoric encounter for families. Thousands of years ago, prehistoric mastodons, woolly mammoths, and ancient bison were drawn to the site's natural sulfur mineral springs. Today, families can view a live herd of magnificent American bison grazing in scenic autumn pastures from elevated viewing platforms. The paved Discovery Trail winds past life-sized replica sculptures of prehistoric beasts trapped in ancient bogs, alongside interpretive signs explaining Ice Age paleontology. The indoor visitor center museum features authentic mastodon bones, tusks, and fossils excavated right from the park grounds. Family Experience & Accessibility: • Stroller Accessibility: Paved pedestrian walkways connect the visitor museum, bison viewing mounds, and the main 0.5-mile Discovery Trail, allowing smooth pushing for strollers and wagons. • Nursing & Rest Spots: The indoor visitor center features clean, heated restrooms with baby changing counters, a gift shop, and comfortable indoor seating. • Age Suitability: All ages. Young children are mesmerized by the live bison herd and the gigantic prehistoric mammoth and mastodon sculptures. • Sensory Tips: Quiet rural Kentucky state park with scenic open pastures, gentle autumn breezes, and fascinating natural history.
