"One of the city’s oldest institutions and the largest natural history museum in the western U.S., this museum houses fantastical fossils and skeletons plus other mind-blowing objects. The collection contains almost 35 million specimens and artifacts that stretch across a timeline of some 4.5 billion years. A $75 million transformation will debut in 2024 with a new 75,000-square-foot indoor-outdoor wing." - Travel + Leisure Editors
