I know gravel can be a cool landscape design element. I have seen on this site
https://www.lasdstudio.com/ several examples of the use of this material in the garden and its decoration. I believe that besides the common gravel paths, there are many other creative ideas for how this can be used in garden decoration. I'm sure that only experts in this can find such bold design solutions, so I advise you to contact one of the landscape design services in your area. These guys helped me, but they only work in San Diego, California.
