Hotel operator Four Seasons has opened its fifth Hawaiian resort; a new property on the island of O’ahu.

The Four Seasons Resort O’ahu at Ko Olina is located on the ocean in the community of Ko Olina. At the heart of the property is a 17-storey terraced hotel – originally designed by architect Edward Killingsworth in 1998 and now renovated by Honolulu studio Philpotts Interiors – that was once the centrepiece of a previous resort.

The renovated building features 371 ocean and lagoon views and several restaurants decorated in authentic Hawaiiana style, inspired by nature and featuring traditional local woods and banana-leaf wall coverings.

The resort offers access to beaches and several pools overlooking the Pacific Ocean. There is also an on-site tennis centre, expansive gardens and a custom-built wedding chapel.

A 35,000sq ft (3,250sq m) six-storey spa and wellness complex has also opened, with 14,200sq ft of outdoor space. It has door and outdoor treatment rooms with treatment menus inspired by ancient Hawaiian healing traditions; a health club and gym; steam, sauna, whirlpool facilities; an outdoor lap pool; a hair and nail salon and a barber shop.

“Our name ‘Ko olina’ literally means ‘place of joy,’ a sentiment that comes to life from the moment you arrive,” said general manager Sanjiv Hulugalle. “We look forward to welcoming guests to our island ohana for the first time this summer, and then again and again.”

The resort has been developed by The Resort Group (TRG), one of Hawaii's largest landowners of resort developments; Westbank (WB), a Canadian luxury hotel developer; and Four Seasons.
