Four Seasons Hotels & Resorts has opened its first Vietnamese resort – a luxury development in Hoi An, on the country’s central coast.

The Four Seasons Resort at the Nam Hai, Hoi An is home to a 14,018sq m spa, with eight lake villas complete with overwater relaxation pavilions with their own crystal singing bowls. The Heart of the Earth Spa’s treatment suite has an entire octave set of alchemy crystal bowls with the “ability to alter the vibration of the whole resort”, which Four Seasons says is “a first for any spa in the world”.

Treatments centre on vibrations channelled from the crystal singing bowls, which are tuned to 432 hz – “the pulsing intonation of nature”.

Each treatment is grouped into one of three wellness principles of stability, creativity and non-judgement and treatments include massages, rituals, body treatments, facials, manicures and pedicures (with vegan spa nail products). Each treatment room has its own steam room and there is also a yoga deck based within the spa premises.

Product lines on offer include Ila, Aromatherapy Associates and Spa Ritual.

Inspired by the teachings of Vietnamese monk Thich Nhat Hanh, visitors are encouraged to write their own ‘Love Letter to the Earth’ at the Heart of the Earth Spa. It is managed by Four Seasons regional (Asia Pacific) spa director Luisa Anderson (based in Bali) and spa manager Made Dwi Susanti (based at the Hoi An resort).

No consultants were used during the build process, however, Anderson was directly involved in creating the spa’s concept, treatment menu and training.
