The Spa at The edge, Bali

Clinging to the rock face of a stunning sea cliff, the Edge Spa defies conventions and, ... gravity.
Designed to fuse with its surrounding the spa skims above the azure blue sea.  With liquid floor, wall-less rooms, and sensuous curves-- its lightness of being seduces and liberates the senses, coaxing them to suspend disbelief. 
The spa’s innovative design may break new grounds, but the soul of the spa is as old as Bali itself. The Edge Spa offers quintessentially Balinese spa experiences inspired by the four basic elements of a simple Balinese temple offering (canang): sacred flowers, blessed water, life-giving rice, and sincere devotion.
The Edge Spa features wet and dry treatment areas, private steam coves and unobstructed views of the Indian Ocean. It also offers a selection of in-villa baths and treatments.

Awarded by Asia Spa Magazine as 2010's Most Innovative Spa of the Year.
