The Atrium at HATC
A 4,000 sq ft elevated event space in the heart of Big Bear Lake
The Atrium at High Altitude Training Center is a one-of-a-kind, light-filled venue designed for brands, creators, companies, and private hosts who want something different than a hotel ballroom or lodge conference room.
With soaring two-story ceilings, floor-to-ceiling windows, and a seamless indoor-outdoor flow, The Atrium blends alpine energy with modern design—perfect for events that want space, presence, and personality.
- Private, design-forward space (not a generic venue)
- Natural light + mountain energy = instant atmosphere
- Built for brands, creators, and experiences—not weddings on autopilot
- Integrated with a high-performance campus if you want wellness, fitness, or recovery layered in
- Big Bear location, two hours from LA—but a world away from boardrooms
Available daily: 5:00 AM – 2:00 AM
Weekend events: Available upon approval
Flexible load-in / load-out windows
Early morning and late-night programming welcomed
