Extra Large River Rock

5.011 reviews

Rounded 4–8" stone for creek beds and slopes

Extra large river rock is natural stone tumbled smooth and sized 4 to 8 inches. At this size each stone reads on its own, so it's the pick for dry creek beds, the edges of drainage channels, slope edges, and accent features where smaller rock would look lost or wash out. Size varies slightly by location, and the natural color mix varies by location and darkens when wet.

Extra large river rock is rounded natural stone sized 4 to 8 inches, big enough to anchor creek beds and slopes, not gravel you spread for a bed or path.

Also called: 4-8 inch river rock, jumbo river rock, oversized river rock, landscape cobbles, big river rock, river stone cobbles.

Beautiful rock, better than pictured. Nina was very proactive and helpful in the coordination of delivery of 5 tons of rock to ensure that expectations were set correctly and exceeded. Great communicator! We were able to fill the whole front of our house flower buds with beautiful river rock and all around the back of our pool cage.

Frequently Asked Questions

Use the calculator with your length, width, and depth. Stones this size need a layer about 6 inches deep to cover the ground. One ton covers about 40 square feet at 6 inches deep.

Line the channel with landscape fabric, set the extra large stones along the banks and at the bends, then fill the bottom with smaller river rock. Mixing sizes looks more natural than one size alone.

It holds well on gentle slopes and in normal yard runoff. Rounded stone can roll, so on steep banks or where water moves fast, use riprap. Its angular faces lock together.

Yes. Most stones run a few pounds up to about 25 pounds, so one person can set them. Wear gloves and lift with your legs. A wheelbarrow helps move them from the pile.

No. Stones this size are uneven and roll underfoot. For paths, use smaller rounded stone or set stepping stones through the rock.

By dump truck, straight to your property. The driver dumps it in one pile where you choose. Pick a firm, level spot the truck can reach, clear of cars and overhead wires. Delivery is included in the price you see.
