Any natural stone with a nearly flat surface might be used as a stepping stone. A walkway or even just a set of single stones set firmly into the soil creates a natural looking path that may lead straight to the destination of the dock or may wander around some scenic areas along the way. Such stones need only to be of reasonably uniform size and should be placed at a comfortable space apart for most pedestrians.
The rough surfaces of flagstones are appropriate to use as stepping stones. They may be set in soil where sod has been removed and secured with soil backfill. Replace sod around the stones, or sow with grass seed for a natural appearance.
Manufactured patio blocks that can be purchased in a variety of sizes up to 24 x 24 inches may make a simple path to and around a dock, but the patio blocks will also lend themselves to forming a platform at the base of the dock, which is an appropriate spot for sunning, resting after swimming and other leisure activities, including dining. Select patio blocks with enough texture to make for secure footing in wet conditions.
Creating a path or platform of stepping stones is an opportunity to use manufactured patio blocks with solar lighting built into the block. This useful and practical feature offers enhanced safety to residents and guests.
Making patio blocks or round stepping stones at home is a rapidly growing hobby. Several manufacturers offer kits containing the ready-mix concrete, plastic or disposable forms and decorative items to set into the blocks. Enterprising crafters can gather the materials for making the blocks much less expensively and offer family and friends an opportunity to create personal works of art in stone.
