The Suite is decorated in Dude ranch style honoring the Old West. It is a bright and airy suite with big windows on two sides looking out to the pool and hills and rocks that nestle protectively behind the Inn and Spa. Decorated in warm terra cotta and natural colors, the Diamond S Suite sports a double bed and a trundle-settee and can sleep up to four people.

It has a one-half bath and is one of the favorite suites in the Inn.
