The essential purpose of a path is to provide a route between one part of the garden and another. Usually there will be a hard surface of some sort to allow you to keep out of the mud in wet weather. The path designs shown below use pavers and pebbles and demonstrate the many different ways these materials can be used to create attractive and practical walkways. I came across these ideas in an article by Lauren Dunec Hoang which I found on the Houzz website.

Garden paths made of pavers set into gravel are one of the most popular walkway styles due to their natural look, permeability for rainwater and versatility in design. Given the wide range of materials available and opportunities for different combinations, walkways made of pavers and pebbles work with all garden styles. For example, you can pair poured concrete slabs with dark gravel for a contemporary look or set irregular flagstones in warm-toned decomposed granite for a more Mediterranean feel.
If you?re considering adding a pathway of this style, there are a number of things you will need to consider, including the range of costs for materials and installation, whether or not to hire a professional and how to reduce the gravel traveling onto the pavers.
