Wilderness travel defines New Zealand, where spa culture goes back to nature at the new Aro H Wellness Retreat (www.aro-ha.com, first picture), near Queenstown. It subscribes to a less-is-more approach, focusing on simple rooms, vegetarian food, Vinyasa yoga, subalpine hiking, meditation and therapeutic massage. Accommodation is in 11 eco-friendly, modern wooden buildings overlooking Lake Wakatipu in the Southern Alps (from NZ$2,250, about £1,135 per person, for a three-day “Jump Start”, all inclusive). Alternatively, check out of the world by checking into a treehouse – the new headline suite in wood and honeyed stone at La Sultana Oualidia (www.lasultanahotels.com; treehouse from MAD6,150, about £455, second picture) on Morocco’s Atlantic coast. The suite looks towards the lagoon harbouring Morocco’s famous oyster beds and pink flamingos – a scene coloured with that same feeling of a forgotten world that infuses not only the novels of Paul Bowles but, for trailblazers such as Wateridge, the most compelling kind of travel.
