River Rock: Uses, Coverage & Calculator
Smooth, naturally rounded stone that brings color and texture to beds, borders and dry creek beds.
What is River Rock?
River rock is naturally tumbled stone with smooth, rounded edges. Sizes and colors depend on the source, so check the product page for what is available in your area.
It is mainly decorative, but its open structure also handles water well. That makes it a natural fit for dry creek beds, downspout splash areas and borders that need to drain.

River Rock questions
Quick answers to what customers ask most.
Can I walk on river rock?
It is uncomfortable as a path because the rounded stones roll. Use walkway gravel or stepping stones through river rock beds.
How much area does a ton cover?
At 3″ deep, about 80 sq ft per ton, depending on stone size.
Does river rock keep weeds away?
With landscape fabric underneath, it does a good job. Without fabric, weeds will grow between the stones.
