River Rock vs Gravel
Practical differences between smooth river rock and angular crushed gravel, and when to use each.
Smooth river rock is decorative and drains freely but does not compact, so it is a poor surface for driving or walking. Angular gravel compacts into a firm surface and is the right pick for driveways, paths, and paver bases.
Shape drives use
Round stones roll under load; angular stones lock together. Use round river rock for looks and decorative drainage, angular gravel for anything that has to bear weight or foot traffic.
Cost
River rock costs more per cubic yard than crushed gravel because it is sorted and washed. Bulk pricing is usually 2 to 4 times higher for river rock, depending on size and region.
