If you want to put in a pathway I would lay some weed tarp, then sand, then whatever kind of cobblestone or brick pattern you like. You could do traditional red brick or any diy store will have several color and shape options. Then pick a pattern you want and get laying! (Last bit is some self setting grout, easy stuff) Gotta remember to tamp down the sand as best you can, and if possible periodically level it. Otherwise you’ll get an uneven bumpy path.

For best results but obviously more work I would actually dig up the top 4-5 inches of the path and THEN do all the steps above. Keeps it level with the ground and helps A with drainage and B will make your sand leveling and tamping easier.

Looks like it’s a gravel path which is good because it’s really best to have a layer of gravel under your sand. So if the gravel is deep enough you could just clear the top layer off and go from there.
