Denver's Union Station is a two for one: it's a working public transit station and a highly praised dining and shopping center. The station was a huge success when it first opened to the public in 1881, providing railroad service until the center of the building caught fire in 1894. The architecture from the 1917 redevelopment remains and today, it's home to an Amtrak hub and a bus concourse. Located in the hip Lower Downtown neighborhood (aka LoDo), with multiple dining options and boutiques, and The Crawford Hotel, Union Station is a newfound entertainment center.

Did you know that you can actually walk along dinosaur tracks? Well, you can and you can do it in this very state.
