Castle Hot Springs
Arizona
Castle Hot Springs sits in a remote stretch of Sonoran Desert northwest of Phoenix, with natural geothermal springs at the centre of the stay. Access is reserved for registered overnight guests aged 18 and over, keeping both the springs and the wider resort within a small residential setting. Individual accommodation uses Southwestern textiles, ironwork and masonry. Spring Bungalows include private heated outdoor soaking tubs and indoor and outdoor fireplaces. At Harvest, produce from the resort’s farm shapes seasonal meals, with herbs, vegetables and fruit grown on site. Days can include farm tours, guided hikes, yoga, archery and pickleball, while e-bike trips and a via ferrata climbing course offer more active ways to explore the surrounding terrain.
