Steps and walkways are transitional areas that lead you to a destination. This said, the transitional area should be of similar "theme" or style.
Walkways can be completely paved with interlock or natural stone, straight or curved. Within this, you can pick the pattern of the stone (random or patterned), pick designs (such as incorporating a circle or diamond within the walkway), or pick the border. You can can also mix materials, such as a beach pebble walkway with natural stone steps and stone edging.
Walkways do not have to be completely paved, you can use solely stepping stones or line the path with plants and garden beds.
Steps add interest to your area. As they do take up a bit of space per step, you want to make sure that the design and style is prominent and eye-catching.
