Phulay Bay, a Ritz-Carlton Reserve (Nong Thale, Krabi)
The inaugural Ritz-Carlton Reserve, opened in 2009 on a remote Tab Kaek Beach in Krabi with a 1:5 staff-to-guest ratio that remains among the most generous in luxury hospitality.

Eighty-eight all-pool hillside villas above a private cove on the Gulf of Thailand, each with an infinity pool and heated jet pool, on a property anchored by the MICHELIN Guide-recognized Saffron restaurant serving refined Thai cuisine.
