Below the surface: Three luxury underground retreats

If you’re a seasoned traveller looking for a once-in-a-lifetime hotel experience, look no further than under your feet.

Venture underground or underwater to discover these phenomenal holiday destinations that are as awe-inspiring as they are luxurious.

Conrad Maldives Rangali Island in the Maldives

Slumber among the fishes at The Muraka, an extravagant US$15 million residence opening in November 2018 at Conrad Maldives Rangali Island. Wholly immersed in the natural seascape of the Indian Ocean, this two-level overwater bungalow features a powder room, gym, butler’s quarters, bar, dining room and more.

Take a dip in the infinity-edge pool and unwind with a cocktail on the sunset-facing deck before making your way five metres below sea level to a luxurious king-sized bedroom – complete with 180-degree views of the surrounding coral and sea creatures.

La Cocaliere in Courry, France

Head to France for the opportunity to sleep inside one the country’s most impressive caves, La Cocaliere. Hollowed out of limestone rock more than 130 million years ago and located 50 metres below the surface, this spectacular underground sanctuary is just one cavern in a huge 30-kilometre network.

Thrill-seekers can stay the night in the heart of the cave with their very own transparent pyramid to call home. Instead of sleeping under the stars, guests can enjoy 360-degree views of glittering stalactites and precious calcite crystals.

Manta Underwater Room at The Manta Resort, Zanzibar

Anchored 250 metres off the coast and surrounded by nothing but the turquoise Indian Ocean, the Swedish-engineered Manta Underwater Room lets you delve under the sea to get up close and personal to the vibrant marine life that lies below the surface.

Venture up to the roof of the suite for sun tanning by day and stargazing by night, before going down to your secluded submarine bedroom bubble where you can watch the world float by.
