Our Hotel
St Julien Hotel & Spa opened in 2005 and debuted as the first world-class hotel and spa to open in downtown Boulder in nearly 100 years. Boasting unprecedented views of the Flatirons mountains, the hotel’s sophisticated and sustainably designed architecture and landscaping embraces Boulder’s independent spirit and natural surroundings. Nature meets nurture. Style embodies simplicity. All balanced perfectly with luxurious accommodations and top-notch service. A distinguished member of Preferred Hotels & Resorts Worldwide, St Julien Hotel & Spa represents the finest destination hotel and spa that Boulder has to offer.

St Julien Hotel & Spa also works together with the City of Boulder towards the goal of Zero Waste.
