Here are Boulder hotels that advertise a rooftop/rooftop‑style bar, terrace or rooftop pool — with a short note about each:

• Limelight Boulder — rooftop social club/rooftop terrace with pool and bar/lounge. (limelighthotels.com)
• Moxy Boulder — rooftop deck/terrace (hotel features a rooftop deck, hot tub and outdoor social spaces). (bouldercoloradousa.com)
• Embassy Suites / Hilton (Boulder) — property promoted as having Boulder’s rooftop pool and on‑site bar/restaurant (Brickstones). (travelboulder.com)
• St Julien Hotel & Spa — hotel restaurant/ bar with an outdoor terrace that offers Flatirons views (terrace seating for Jill’s/T‑Zero; indoor lounge as well). (Note: St. Julien’s terrace is a prominent outdoor dining/lounge space rather than a full rooftop bar.) (stjulien.com)

Notes and tips:

• “Rooftop” can mean different things: some hotels advertise an actual rooftop bar/pool (Limelight, Moxy, Embassy Suites) while others offer elevated terraces or garden patios with views (St. Julien). I cited the hotels’ listings and local tourism sources above. (hotels.com)
• If you want hours, reservations, or to confirm whether rooftop spaces are open for the date you plan to visit, I can check availability/hours for any specific hotel and date.
