If your legs are weary after mountain biking or hiking, or you just want to cosy up with your significant other, these private, wood-fired hot tubs could be just the ticket. Choose between a 90-minute soak in a tub (each has its own dressing room) or a two-hour session in a ‘wellness pod’, which includes a sauna.

These tubs are popular – book ahead online (last booking 8.30pm). Clothing is optional and the chemical-free glacier and snow-melt water is changed after each booking; the used water is recycled for irrigation. The concept is Japanese, but with the surrounding mountain ranges, the lakeside setting and a pristine night sky, you could only be on the South Island of NZ. Therapeutic massages (30/60/90 minutes $65/120/170) and other treatments are also available.
