The feel of gravel can vary depending on the size and shape of the gravel pieces, as well as the texture of the surface they're on. Generally, gravel feels rough and coarse to the touch, with a gritty texture. The larger the gravel pieces, the rougher the feel will be. Smaller gravel pieces can feel more like sand, with a smoother texture. Gravel can also be sharp and uncomfortable to walk on if it's not well-maintained, particularly if there are larger rocks or pieces of debris mixed in.
