Mohonk Mountain House

Mohonk Mountain House: An Award-Winning Fitness Amenity Designed for Guest Experience

New Paltz, NY

Mountain High Wellness in the Heart of the Hudson Valley

Surrounded by cliffs, forests, and panoramic Hudson Valley views, Mohonk Mountain House offers a setting where nature and hospitality exist in perfect harmony. Every detail from accommodations to amenities reflects a commitment to guest experience.

Since first outfitting the resort’s fitness center in 2005, Advantage has worked closely with Mohonk, providing preventive maintenance, equipment updates, and ongoing consultation — always with Precor equipment at the core of the facility, delivering the performance and reliability the property depends on. That partnership continued in 2025 with a comprehensive refresh, modernizing strength and cardiovascular offerings while preserving the space’s layout, flow, and character.

Behind the Mohonk Mountain House project

A Collaborative Process

Planning began well over a year before installation. Advantage provided guidance on equipment selection and layout, incorporating guest feedback while maintaining safety and flow throughout the space. Visits, measurements, 2D layouts, and thoughtful recommendations ensured that the facility would meet both operational and aesthetic standards.

“Advantage makes this process easy,” says Stirewalt. “They listen to our preferences and help us balance equipment choices with the space we have. The collaboration has been incredibly productive.”

Facility Design Expertise

Advantage Hospitality Sales Manager Christine Watson guided the Mohonk team through every stage, from consultation to installation. Her attention to detail and industry expertise ensured a smooth process.

“Christine and the installation team worked seamlessly with us. They were professional, attentive, and excited to see the final result. The changeover was effortless.”

Immediate Impact

The recent refresh brought the fitness center up to date with user-friendly, high-performing options, including:

  • Precor Discovery Smith Machine with Olympic plates
  • 5 Precor Vitality selectorized strength stations
  • Precor Functional Trainer
  • 11 Precor Cardio stations featuring P84 touchscreens
  • Escape Fitness functional accessories

Every piece was selected to maintain balance and accessibility in a linear layout defined by natural light and beautiful wood columns and finishes throughout. Framed by the property’s stunning views, the design creates a space that feels open, inviting, and inspiring.

Intentional Spaces, Lasting Impact

The result is a fitness center that feels intuitive, functional, and visually aligned with Mohonk Mountain House’s heritage, allowing guests to move seamlessly between stations and enjoy varied workouts without the space ever feeling crowded.

Since reopening, the facility has received overwhelmingly positive feedback, with Vice President and General Manager Barbara Stirewalt sharing, “We love hearing guests say ‘wow’ when they enter the space — and they do!”

The refresh also earned national recognition, securing first place in a USA Today Readers’ Choice Award, further reinforcing the property’s commitment to guest satisfaction and experience. The redesigned center blends efficiency, accessibility, and visual appeal through carefully planned layouts, versatile equipment, and abundant natural light, creating an inviting and energizing environment that inspires wellness, delights visitors, and reflects a thoughtful, bespoke approach to hospitality design.
