River Rock Cobbles (3” to 7”)

River rock cobbles in the 3" to 7" size range are naturally rounded stones sourced from riverbeds, shaped over time by water flow. This cobble-sized aggregate is larger than typical gravel, offering a distinctive, smooth appearance and substantial weight that helps keep the stones in place.




The generous 3" to 7" size makes these cobbles ideal for decorative landscaping, dry creek beds, erosion control, and garden borders. Their rounded shape is gentle on bare feet and reduces the risk of injury, making them suitable for pathways and play areas. While they provide excellent drainage and visual appeal, their size and weight make them less suitable for compacted surfaces or driveways. River rock cobbles are a popular choice for both residential and commercial projects seeking a natural, low-maintenance, and attractive finish.
