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.
Environmental Commitment and Stewardship
St Julien Hotel & Spa is committed to minimizing our impact on the environment. As a committed Colorado green hotel, we realize that the decisions we make as an organization affect not just the environment of the Hotel, but also that of the community. In an attempt to improve our environmental efforts, St Julien has formed a Green Committee, whose goal is to spearhead efforts that will reduce the Hotel’s footprint on the community – all while maintaining the high level of service and quality sought by our guests. St Julien Hotel & Spa also works together with the City of Boulder towards the goal of Zero Waste.
