Fodor's Expert Review Parque Paleontológico Bryn Gwyn

Just south of Gaiman the green river valley gives way to arid steppes where clearly visible strata reveal more than 40 million years of geological history. Some 600 acres of these badlands—many of them bursting with fossils—make up the Parque Paleontológico Bryn Gwyn, a branch of the Museo Paleontológico Egidio Feruglio in Trelew where a fossil trail and botanical gardens await. Confirm with the museum before going as the park can close periodically after heavy rain.
