The term 'Spring Sites' refers to two different types of locations: Oases (5 letters) and Spas (4 letters). An oasis is a fertile area in a desert, usually with a spring or well that provides water for plants, animals, and humans. A spa is a health resort that offers treatments such as massage, facials, and other therapeutic services. Both oases and spas provide a place of relaxation and rejuvenation.
