"The O2 Lounge was an absolute lifesaver for me during our trip. My blood oxygen levels were hovering around 65–85% most of the time, and the altitude really hit me harder than expected. I stopped in almost every day for a 45-minute session, and each time I left feeling noticeably better. It made a huge difference in how I felt for the rest of the day and allowed me to actually enjoy the trip instead of just pushing through the symptoms. If you’re dealing with any altitude sickness, I highly recommend coming here. The service was great, the staff was friendly and helpful, and the whole process was easy and relaxing. I did the “relax” option almost every time, and it was perfect. Can’t say enough good things — this place genuinely helped me get through the trip."

"this lounge is such a great place to relax and the service here is amazing! they did a great job informing me about altitude sickness. the oxygen boost helped me a lot before going skiing."

"This place made me feel 100% better , truly. I didn’t even realize how much I needed the care, kindness, and understanding I found here. It felt like a hidden gem placed in my path at the perfect moment. Guy and his staff treated me with such compassion and patience, and I’m genuinely grateful. Thank you, Guy… you and your team were a blessing when I needed it most."

"Excellent experience! Oxygen session and great drink menu including smoothies (mine was delicious). Sally and Skylar were so wonderful and welcoming. Great lounge with a variety of comfortable couch and bar seating options. Great prices and options!"

"We are from Louisiana, coming to Colorado hurts 😆 Stop at this place 100%. Excellent prices and service. You can get coffee or tea while recouping with o2. The gentleman helping us was impressively attentive. I don't have 1 negative thing to say. Wonderful service, atmosphere, and beverages. Would definitely recommend."
