Crisp air, the heady fragrance of Australian-made Waterlily botanicals and the comforting heft of solid, 19th-century stone walls all contribute to a profound sense of wellbeing at the new Stables Day Spa at Mount Lofty House. Perched just below the summit in the Adelaide Hills, this MGallery Collection hotel was built in the 1850s as a summer house by the Hardy family, who lived in a “sort of feudal splendour”, their carriage horses enjoying an equally grand time in a handsome stable block in the garden. The horses are gone and the building restored to house three whitewashed treatment rooms, where the aptly named Jasmin scrubs, pummels, massages and hydrates your jetlagged correspondent in a two-hour signature spa ritual, deploying a fragrant arsenal of potions and lotions. Pots of lavender, shot-gold drapes and simple adornments make this a serene and cosy retreat, especially when the hotel is wrapped in mists and the scent of woodsmoke drifts across orchards and vineyards in the valley below. The new day spa prefaces a multi-million-dollar upgrade of Mount Lofty House that will include nine luxury guest suites. More: mtloftyhouse.com.au.
