Treat yourself to the refreshing air of the Rocky Mountains, nestled between the front range and Boulder flat irons at the St Julien Hotel & Spa. A destination where nature and luxury have merged, unparalleled services in an outstanding city is the perfect pair. A few steps from Pearl Street mall show off the style and sensibility of this casual city. Relish in a retreat specifically created for good times, relaxation and renewal. The neighboring hillsides offer breathtaking views during hikes, mountain bike excursions, or back country snow shoeing. You are at the center of it all, while being wonderfully hidden in the sanctuary of a vacation dream. Stacked with an infinity pool, complimentary fitness center, and 10,000 square foot spa, signature amenities make your stay that much sweeter.

I am very privileged to stay at the best hotels worldwide, but there aren't many who leave me feeling joyous to arrive and sad to leave...a place i call my Rocky Mt home. I have recommended the St Julien year after year to friends and colleagues. The staff, the exceptional care - REAL care, is astounding. I will miss you until next time. There isn't a hotel in the world that literally makes me want to skip thru the lobby with open arms. And has me joyous to join a spa experience. And if you are lucky to have a room with a Flatiron view, you will feel enveloped and loved by the spirit of the Arapaho all around you.

Extremely unprofessional front desk staff, very disrespectful and unhelpful.

St Julien Hotel & Spa is one of those rare places that truly gets it right—every single time. We live just a couple miles away and still choose to staycation here a few times a year, which says everything. From the moment you walk in, you’re welcomed in a way that feels warm and genuine, not pretentious. Being greeted by name, thoughtful room upgrades, and the kind of service that feels personal without being overdone—it all adds up. The details are what make it special. Turndown service with slippers and a genuinely delicious piece of chocolate feels like such a treat. Inside the rooms, everything is simple, clean, and beautifully maintained. The Nespresso makers are a perfect touch, and the soaking tubs make it feel like a true reset. It’s never over the top—just thoughtfully done and consistently cared for. Outside of the room, the experience carries all the way through the property. The espresso martinis at the bar are some of the best—Troy at T-Zero absolutely nails them. Meals at Jill’s, time spent in the lobby—it’s all inviting without ever feeling overdone. You can just settle in and enjoy being there. What stands out most is the staff. From front desk to housekeeping, everyone is kind, attentive, and genuinely seems like they want to be there—which, to me, says they’re being treated well too. The pool and hot tub are a highlight, especially with views of the Flatirons—sometimes snow-capped, which never gets old. The space is always clean, stocked with fresh towels, and clearly checked on frequently. It’s simple, but done really well. We’ve had rooms overlooking both the mountains and Walnut Street, and the balcony views are incredible. It’s the kind of place where you can get work done, step out for a hike, and come back to something that feels like a true escape. As someone who’s spent years in the service industry, I notice the details—and they get them right. Every time. We always leave feeling taken care of, and we’re already looking forward to the next stay.

Location was impossible to beat. Room was comfortable and very clean. Bell staff and valets are pros. I don't know if I'd return or find an Airbnb next time, but it's a very nice hotel and doesn't deserve some of the silly poor reviews it receives. It's a solid 4/5. That said, I'd have gladly paid 40-50% more for a 5/5 wow experience... I'm not sure Boulder has that right now.

Concierge Desk is the greatest! Catherine Nate and Michelle were so delightful and helpful. Best recommendations and supreme service. Bellboys and valets are incredible too. Everything is always so easy and taken care of when I stay here. Thank you St. Julien staff. It’s always a wonderful experience! The pool is my kids favorite too.
