The $250m (£132m, 188m euros) Morongo Casino Resort and Spa in Cabazon, California will open in early December.
Designed by The Jerde Partnership – which was also involved with Las Vegas landmark hotels The Bellagio and Treasure Island – the resort is owned by the Morongo Band of Indians.
The property boasts a luxury pool with cabana and waterslides alongside restaurants, nightclubs and a kids arcade.
The full service Sage Spa at the resort boasts a spa pool and swimming pool alongside an extensive selection of treatments.
It is predicted that the Morongo will add $2.8bn (£1.05bn, 1.5bn euros) to the economy within five years, including the creation of 4,000 jobs.
The resort will officially open to the public 10 December. Details: www.casinomorongo.com
