* This spa has caught my attention before and I hope to visit it soon and report back personally. Savvy and creative spas grown their own spa products Extract: By an IMPRESSIVE margin in this listing the best website for relating the spa and the products used to the sustainability program of the whole property was the Yaxkin Spa at the Hacienda Chichen Resort in the Yucatan, Mexico.
Of course there are many special places that don't make these lists, often because they are small and relatively unknown (part of their great charm). Give them your own mention in the Comments below.
Here is my favorite mineral spa: Harbin Hot Spring
