Rising 45 storeys, this building is a landmark on Denver’s horizon. Its restaurant, Edge, is at the bottom, allowing diners to observe and soak in the streetside downtown buzz. A spa occupies the third floor, with a salon, hot tub and steam room. While up on the rooftop, you’ll find an outdoor pool, a whirlpool and an alfresco bar — overlooked by a state-of-the-art fitness centre. The Four Seasons’ skyscraper houses 239 guest rooms decorated in an urban-chic contemporary style, with huge picture windows (book a suite with a freestanding tub for a bath with a view).
