Luxury river cruise operator Haimark is launching a spa-focused, seven-night river expedition on its new ship, the Mekong Princess.

The 12-suite Mekong Princess includes the Princess Spa, a large treatment room with full-glass French balconies facing the river that will offer Southeast Asian-inspired treatments, including massages, facials, scrubs and body wraps. The spa will use the Bodia Spa product line.

Each guest will receive a complimentary one-hour Princess Spa treatment during the sailing.

The inaugural September 17, 2015 sailing will include an itinerary through Vietnam and Cambodia down ancient river tributaries with visits to tiny village outposts, floating markets and a bird sanctuary.

The ship also includes a fitness centre as well as daily yoga, Tai Chi and meditation classes, some of which take place on the open-air Bassac Deck observation area.

The ship also includes a library, internet lounge and entertainment lounge, while the French Colonial Indochine dining room serves spa cuisine along with multi-course Southeast Asian and Western fare.
