Extra Large River Rock
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.

Extra large river rock is the biggest rounded stone in the family. Pick river rock for beds and borders, or riprap where fast water or steep slopes need stone that locks together.

I initially ordered the wrong amount but the customer service representative, Jenel, helped me out by correcting it and giving me a refund immediately. I advised them where I would like the dirt to be dumped in my backyard and the driver made it happen. Great experience working with Jenel and Hello Gravel.

I work for an industrial construction company that deals with a lot of civil work, and I'm very accustomed to building a proper base with specific materials on projects we work on. The people at Hello Gravel were very pleasant to deal with. Prices are good. Unfortunately, the product I asked for wasn't available after paying for it, but they worked hard at ensuring I had a suitabe alternative. In the end, it all worked well, and the staff were very attentive. Lots of operators would not have gone through the trouble they did to make sure I was happy as a customer. Hello Gravel did

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.
