The St. Regis Red Sea Resort: Kengo Kuma private island paradise on Ummahat with Tilina overwater dining, shell-shaped villas, and St. Regis Spa

Reigning with striking biophilic seashell architecture designed by master architect Kengo Kuma and Red Sea grand palace nobility on the pristine private island of Ummahat in the Al Wajh lagoon, Tabuk Province, Saudi Arabia (surrounded by vibrant untouched coral reefs, accessed via a 40-minute chartered catamaran cruise or 20-minute seaplane from Red Sea International Airport), The St. Regis Red Sea Resort opened in 2024 as Saudi Arabia’s premier ultra-luxury private island and overwater villa grand palace. Designed by world-renowned architect Kengo Kuma, the 90-villa luxury palace is wrapped in organic timber curves, sweeping sand-dune-inspired rooftops, and overwater spiraling walkways. Centered around the acclaimed overwater fine-dining institution Tilina, the Japanese Nikkei restaurant G福 (Gishiki 45), an expansive outdoor heated freshwater swimming pool with private cabanas, 24-hour dedicated St. Regis Butler service, and the palatial Forbes Five-Star St. Regis Spa, this property is the Red Sea Project’s ultimate visionary grand palace.

Arrival introduces travelers to unvarnished Arabian island glamour and Ummahat historic splendour: liveried St. Regis Butlers greet guests at Red Sea International Airport before boarding the private seaplane or catamaran across the crystal turquoise lagoon, arriving at Kengo Kuma’s spiraling overwater welcome pavilion where conch shells sound, and sipping chilled date-water infusions or mocktails with warm artisanal Red Sea crab canapés. Day-one logistics focus on coordinating bespoke Red Sea marine, diving, and island pursuits: snorkeling directly from your overwater villa deck into the untouched fourth-largest barrier reef system in the world (steps away), private guided scuba diving expeditions among coral pinnacles and hawksbill turtles (in resort), private chartered catamaran sailing through the desert archipelago (in resort), swimming across the beachfront pool, indulging in Arabian oud and 24-karat gold therapies at the Forbes Five-Star St. Regis Spa, watching the daily evening sunset Champagne (non-alcoholic) Sabering ritual, and reserving an overwater table for dinner at Tilina.

Palace living balances active Red Sea marine exploration with serene desert island sanctuary wellness: The St. Regis Spa features private luxury treatment suites, outdoor vitality whirlpools, steam rooms, saunas, an outdoor heated swimming pool, and therapies utilizing Arabian frankincense, gold, and ESPA skincare. Dining is an extraordinary Modern Overwater-Nikkei culinary summit: elevated overwater fine gastronomy at Tilina (celebrated for dry-aged meats, local Red Sea seafood, and fine non-alcoholic pairing creations), Japanese Nikkei cuisine at G福 (Gishiki 45), Mediterranean dining at Nesma, and 24-hour in-villa royal dining.

Accommodations comprise 90 expansive overwater villas and beachfront dune compounds styled by Kengo Kuma in warm curved timber boiserie, bespoke natural linen fabrics, deep freestanding marble soaking bathtubs, private outdoor plunge pools, and private furnished sundecks framing the turquoise lagoon ranging from 120 to 450 square metres. Each residence features plush king beds with custom linens, and marble bathrooms with deep soaking bathtubs, embedded TV mirrors, and custom Remède amenities.

Island purists, Kengo Kuma architecture devotees, and luxury travelers seeking untouched Red Sea barrier reef seclusion, overwater villas, and St. Regis Butler service should book The St. Regis Red Sea Resort without hesitation.
