Perched 400 feet above Avalon Harbor on Catalina Island, Mt. Ada Los Angeles transforms the former summer estate of chewing gum magnate William Wrigley Jr. into Southern California's most exclusive luxury retreat. This Georgian Colonial mansion, built in 1921 as a private family residence, offers discerning travelers an intimate escape where historic grandeur meets personalized hospitality just 22 miles from the mainland.
The Story & Heritage Mt. Ada's distinguished heritage begins with William Wrigley Jr. and his wife Ada Elizabeth, who commissioned this 7,000-square-foot mansion as their Catalina Island sanctuary. Following Wrigley's death in 1932, the estate welcomed princes and presidents before its transformation into a luxury boutique hotel in the 1980s. Meticulously restored to preserve its 1920s splendor, the property has earned prestigious accolades including Conde Nast's "Best in the World" recognition and Forbes Travel Guide Four-Star Award. Operated by the Santa Catalina Island Company, Mt. Ada maintains its legacy as the island's premier luxury accommodation, where architectural details like handmade dentil moldings, stately columns, and French doors reflect its storied past.
Accommodations & Design With only six ensuite guest rooms accommodating a maximum of 14 guests, Mt. Ada ensures unparalleled exclusivity and personalized service. The crown jewel, the Grand Suite, occupies Wrigley's former bedroom and features a 280-square-foot private balcony with commanding harbor views. The intimate Garden Porch room, though compact at 181 square feet, offers charming garden vistas, while select accommodations include original fireplaces and private balconies. Each room maintains the mansion's residential character with period-appropriate furnishings and modern luxury amenities. The 2-to-1 guest-to-staff ratio ensures attentive service throughout this ultra-luxury property, where guests enjoy panoramic views of Avalon, the Pacific, and on clear days, the California mainland.
Experiences & Amenities Dining at Mt. Ada centers on the formal dining room and spectacular wraparound terrace, where breakfast and lunch are included in the stay. The former billiards room, now a cozy den with fireplace and bar, provides an intimate setting for evening cocktails, while The Butler's Pantry offers 24-hour access to wine, port, and light refreshments. Guests enjoy complimentary access to Descanso Beach Club, Catalina Country Club tennis facilities, and the island's golf course. The six-acre grounds provide tranquil gardens where deer and foxes roam, while the hilltop location captures both sunrise and sunset with cooling ocean breezes.
