Sand Tray Therapy Sand tray therapy is a wonderful expressive arts modality that provides a safe and contained space for clients to create a three dimensional world or story using miniature symbolic figures in the sand. Sand tray allows children and adults to express their inner experience with or without words, tapping into deep feelings, and inviting the inner self to heal through expressing and creating a unique story, world or installation art image that is shared and witnessed by the art therapist. The emerging story can hold many layers of meaning and move and change in time and space. Sand tray is simple yet powerful and very accessable for all ages and can help work through challenges symbolically. Different scenarios can be played out in an appealing, interactive, and contained environment.
