Walk on cobblestones. Textures in PBR size 2048. Use two textures, one with light brown white stones or the other with stones of different colors.
You can use Blender’s Array and Curve to make your paths.
You can also crossbreed with three different models, they are:
cobblestones_crossing_a
cobblestones_crossing_b
And to finish the journey:
cobblestones_final
The stones must be buried halfway in the ground.
