Expansive paleontological preserve showcasing rich Pliocene‑era fossil deposits that reveal the ecological history of ancient species.

How to Get There

From Twin Falls (40 mi): Follow US‑30 W through Buhl toward Hagerman, continuing approximately 40 miles to reach the visitor center area.

Overview

The ancient fossil landscape preserves one of the richest windows into the Pliocene epoch, where layers of sediment reveal a world once inhabited by early horses, mastodons, saber‑toothed predators, and a diverse collection of over two hundred species. Visitors can explore sweeping benches above the Snake River Plain, where exposed strata offer clues to long‑vanished ecosystems shaped by shifting climates and evolving fauna. These fossil beds, recognized as among the most scientifically significant in North America, provide a rare opportunity to visualize a prehistoric world that predates humanity by millions of years.

At the modern visitor center, travelers encounter carefully curated exhibits that illuminate the scientific process behind excavation and preservation, including casts and displays that bring the story of the famed Hagerman Horse to life. Trails and overlooks—quiet, wind‑etched, and rich with geologic character—encourage reflection on deep time and the forces that shaped the region. Whether drawn by natural history, paleontology, or the drama of ancient landscapes, guests will find a place where science, scenery, and storytelling converge in a uniquely immersive experience.
