The Sacramento Valley boasts a veritable goldmine of history and activities just waiting to be explored by visitors. Gold was discovered in the valley in 1848, prompting miners from around the globe to descend on Sacramento with hopes of striking it rich. Today, visitors can experience the thrill of gold panning and the culture of the Gold Rush era through attractions such as the Sacramento Museum of History, Science, Space & Technology. The valley is also home to the Sleep Train Amphitheatre, a massive open-air art and concert facility with a capacity of 18,500. Located roughly 25 mi (40 km) southeast of the city of Sacramento, the Sutter Creek Theatre is a former silent movie house that now offers a variety of live entertainment. The Indian Springs Wildlife Trust in Penn Valley houses more than 175 birds that visitors can enjoy. Other destinations in the region include Chico, Yuba City and Marysville.
