World's Most Secret Hotels

We uncover the world's most remote and extraordinary hotels - including a brutalist lodge in Bolivia, a futuristic getaway in County Fermanagh, a mirrored resort overlooking a Norwegian fjord and an art deco hotel nestled amid the Pyrenees.

We visit a majestic, fortress-style hotel that rises like a mirage in the United Arab Emirates. There's a futuristic fantasy in Dorset, a yellow submarine in Ireland, and a hotel built out of repurposed shipping containers in the Australian outback.

An old Cornwall jail becomes a luxury retreat. Opulent ancient caves bring the South African wilderness up close. A Swedish lighthouse shines a light for luxury seekers. And in tropical northern Queensland, an eco-resort offers treetop accommodation.

This time there's a Swiss mountain retreat, a ghostly ancient inn in Rye, the perfect pod for a digital detox, a working lighthouse that's also a luxurious hotel, and a brutalist classic in Mexico.
