Entrepreneurs Phil Stephenson and Robin Paterson, owners of the Petit Saint Vincent private island in the Caribbean Sea, have announced the opening of a treetop spa as part of a major redevelopment of the resort.

The PSV Spa is designed to blend in with its surroundings and has been crafted entirely using coconut trees, driftwood and natural wood. Facilities include four open-air treatment rooms, private outdoor showers and a relaxation area.

Each of the exclusive spa treatments are specifically tailored to the individual guest enabling them to choose which products are used from a selection of carefully blended massage oils made from local herbs, spices and aromatic plants

The treatment menu - featuring Indonesian and Caribbean influences - has been created by Petit St. Vincent's team of Balinese and Caribbean therapists.

Signature treatments include the ancient Shirodhara massage - an Ayurvedic treatment, involving the warm and consistent flow of aromatic oils on the forehead and 'third eye', the chakra point just above and between the eyebrows that is said to be the seat of human consciousness.

The 46 hectare (113 acre) island was acquired by Stephenson and Paterson in 2010. Accommodation is offered in 22 private cottages and other resort facilities include a fine dining restaurant.
