Vista del Lago Water Education Visitors Center is off I-5 at the Vista del Lago Rd. exit above Pyramid Lake. This 18,500-square-foot building offers interactive exhibits about California’s water supply and the California Aqueduct. Exhibits show how ancient cultures reached water supplies as well as the future of water stewardship. Videos tackle such issues as climate change and Earth’s limited water supply. The center’s balcony affords a nice view of Pyramid Lake.
