Spanning 64 acres in Washington Park, the massive Oregon Zoo offers children the chance to see their favorite animals up close and is one of the largest attractions in Oregon. Here, more than 1,000 animals reside in natural, expertly designed habitats like Cascade Canyon Trail, home to black bears, bobcats, bald eagles and river otters. Other exciting exhibits include the Pacific Shores, which features sea otters, polar bears and sea lions. Also, on most days they have a live bird show on the main lawn. Kids especially love the Zoo Railway, a winding one-mile ride around the grounds' perimeter. Kids also love seeing the elephants and the lions.
