Auberge Resorts Collection, a Marin County operator of 10 luxury resorts in North and Central America, the Caribbean and South Pacific, has put the Calistoga Ranch in upper Napa Valley up for sale.

“Calistoga Ranch is one of the highest-rated and most successful boutique luxury hotels in the U.S. that attracts high-end guests from all over the world,” said John Strauss, international director with JLL, in the announcement marketing property. “Its natural beauty and private location present a rare opportunity for investors to buy an iconic, irreplaceable asset in the Napa Valley.”

JLL declined to reveal the asking price. Another luxury lodging property in Napa Valley, the 80-room Hotel Yountville, is selling for $96.5 million, or $1.21 million a room.

Built in 2004, the 50-room Calistoga Ranch resort sits on 157 acres. Each of the resort’s 50 rooms are free-standing lodge units with various indoor–outdoor living amenities such as outdoor living rooms, showers and hot tubs.

The property offers two food and beverage outlets, a spa, 15,000 square feet of indoor and outdoor event space, an indoor/outdoor fitness center, yoga deck and two outdoor pools. The resort also has an on-site vineyard, wine cave, acres of hiking trails, and close proximity to many of Napa’s wineries.

Properties in the Auberge Resorts Collection include Auberge du Soleil and Solage in Napa Valley; Esperanza and Chileno Bay Resort & Residences, Los Cabos, Mexico; Hotel Jerome, Aspen, Colo.; Malliouhana, Anguilla; Nanuku, Fiji; Element 52, Telluride, Colo.; and Hacienda AltaGracia, Costa Rica.

Several others are in development. Auberge Beach Residences and Spa Fort Lauderdale is scheduled to open this year. The Lodge at Blue Sky in Utah late next year, Auberge Resorts Sun Valley in Idaho in 2019 and Stanly Ranch Napa Valley southwest of Napa also in 2019.
