The Spa at Bushmans Kloof Wilderness Reserve & Wellness Spa Retreat, Cederberg Mountains, Western Cape
What: A spa attached to a private reserve in the Cederberg Mountains, which are dotted with red sandstone rocks known for their natural healing energy. Inside, there's a quartz crystal steam room, and treatment rooms have rain showers; outside are four pools and a riverside treatment gazebo.
The look: Neutral if not austere. In reception, a massive hand-cut glass-and-porcelain mosaic depicting the tree of life is the focal point; monastic treatment rooms have pebble floors that are heated in winter.
Who goes: Nature-loving honeymooners and 50-plus city escapees.
The treatment: The Celebration of Life is head-to-toe bliss, with targeted massages for the back, feet, and hands followed by a deeply hydrating Elemis facial.
P.S.: It's worth paying the surcharge to book the riverside gazebo.
