Allegra Spa is the full-service spa within the Summit at Big Sky hotel, positioned at the base of Lone Peak in Big Sky, Montana—one of North America's largest ski areas. Situated at an elevation exceeding 7,500 feet, the spa serves the resort's active clientele: skiers and snowboarders in winter, and hikers, mountain bikers, and trail runners in summer. The spa occupies dedicated space within the Summit Hotel, offering private treatment rooms, a relaxation lounge, and a treatment menu developed with the specific physiological demands of high-altitude mountain guests in mind.
The signature Alpine Mountain Massage combines deep-tissue and Swedish technique with warm oil blended with high-altitude botanical extracts, designed to address muscle fatigue and connective tissue tension that accumulate over multiple days on the mountain. The Powder Day Body Treatment targets the lower body specifically—applying heated stone and targeted compression to legs, hips, and lower back after heavy ski or snowboard use. The Oxygen Facial addresses the distinct skin challenges of altitude: dryness, UV exposure, and reduced humidity, using serums and manual massage to restore hydration and circulation. Nail services including manicures and pedicures round out the menu for guests extending their stays.
Therapists at Allegra Spa are state-licensed and trained in both relaxation and sports performance recovery modalities. The overall aesthetic of the spa is mountain-contemporary—clean lines, warm lighting, and materials that reference the surrounding alpine environment without excessive theming. Couples suites are available for side-by-side bookings.
Big Sky is accessible primarily by car from Bozeman (approximately 45 minutes). Spa services are available to Summit Hotel guests and Big Sky Resort property visitors. Treatment availability follows the ski season (typically November through April) and summer season (June through September), with reduced programming during spring and fall shoulder periods. Reservations are strongly recommended during peak ski weeks—Christmas, January, Presidents' Week, and spring break—and during summer's busiest mountain biking weekends. Prices range from approximately $120 to $250 USD per treatment.

Tips for visiting
- Book treatments immediately at check-in during peak ski weeks—availability disappears within hours during Christmas and Presidents' Week
- The Oxygen Facial is most effective after two or more days of sun and wind exposure at altitude; plan it mid-trip rather than day one
- Drink extra water before and after treatments—high-altitude dehydration compounds the effects of massage and reduces recovery benefits
- Midweek appointments are significantly easier to book than weekend slots throughout both ski and summer seasons
- Gratuity of 15–20% is customary; the spa does not add it automatically, so plan accordingly
Frequently asked questions
Is Allegra Spa open year-round?
The spa operates primarily during ski season (November–April) and summer mountain season (June–September). Hours and treatment availability are reduced during spring and fall shoulder periods. Visitors should contact the Summit Hotel concierge to confirm current schedules before arrival.
Can non-hotel guests book treatments?
The spa primarily serves Summit Hotel guests and Big Sky Resort property visitors. Non-hotel guests may be accommodated on a space-available basis; calling ahead to confirm is advisable before making the trip.
Which treatments work best for post-skiing muscle recovery?
The Alpine Mountain Massage and Powder Day Body Treatment are specifically designed for skiers and snowboarders, targeting the legs, hips, and lower back. The heated stone component of the Alpine Massage is particularly effective for deep muscle soreness.
How far in advance should treatments be booked?
During peak winter weeks (Christmas, January, Presidents' Week) and summer weekends, booking 3–7 days in advance is recommended. Last-minute availability is rare during high-demand periods at Big Sky.
What does the spa offer specifically for the effects of altitude?
The Oxygen Facial is specifically formulated to address altitude-related skin challenges including dryness, UV exposure, and reduced humidity. Therapists are also experienced in altitude-related muscle fatigue and can tailor massage techniques accordingly.
