Berlin, a turn-of-the-century mining town, is preserved in a state of arrested decay. A trail through the town site tells the story of Berlin and its mine. Reamins of Ichthyosaurs (pronounced “ick-thee-o-sores”), ancient marine reptiles that swam in a warm ocean covering central Nevada 225 million years ago, are on display at the park’s Fossil House. These unique official state fossils attract visitors from across the world. A nature trail connects the Fossil House to a nearby campground. Guided tours of the Fossil House are offered from Memorial Day to Labor Day. Currently, Diana Mine is not offering tours. A short distance from the park, visitors can explore the historic towns of Ione and Grantsville. The park is located 23 miles east of Gabbs on State Route 844. The park is open all year, but winter travel may be prohibited due to snow.
