Red Lava Rock

4.91,400+ reviews

Lightweight 3/4–1 1/2" volcanic rock for beds and borders

Red lava rock is crushed volcanic stone full of tiny air pockets, which makes it light and easy to spread. It goes down like mulch but doesn't rot, break down, or need replacing every year. Use it in shrub beds, around cactus and succulents, and along borders where you want warm color with less upkeep. Pieces run about 3/4 to 1 1/2 inch. Size varies slightly and shade varies by location.

Red lava rock is lightweight, porous volcanic stone about 3/4 to 1 1/2 inch that spreads like mulch, not heavy river rock that's hard to move.

Also called: lava rock, red cinder, volcanic rock, scoria, cinder rock, red lava stone.

The order was excellent, the entire process went smoothly. I ordered the walkway gravel for a project around the home and the road base for a patio. The delivery driver placed it exactly where I wanted it and it was delivered on time. Excellent customer service.

Ordered gravel , it was delivered with in a reasonable time. It will need power spayed once it’s spread out but it’s probably expected out of river rock

Google review · Mentions walkway gravel

Once again I had a great second delivery of gravel! We loved having Kevin deliver on time and in just the right space. He was able to back into our steep driveway with great skill. Jodie, who scheduled our delivery kept us up to date with exactly when our delivery would be arriving. I am very pleased with the type of gravel they provide. It looks great on our walkway!

We received the best communication and support during the buying and delivery processes. User friendly links and fast quote, and the river rock is exactly as we pictured it. Would recommend Hello gravel from anywhere in the USA.

Frequently Asked Questions

Use the calculator with your length, width, and depth. A 2 to 3 inch layer gives full coverage. One cubic yard covers about 105 square feet at 3 inches deep.

Lava rock weighs about a third as much as most gravel. Selling it by volume means you pay for coverage, not weight.

Mulch feeds the soil as it breaks down, and you refresh it every year or two. Lava rock doesn't break down, so you put it down once. Pick mulch for beds you dig often. Pick lava rock for shrub beds and borders you want to leave alone.

It's heavier than mulch and the rough edges grip each other, so it stays put in normal wind and rain. On steep slopes or right under downspouts, use edging to hold it in.

It's rough and porous, so wear gloves when you spread it. It's not a good fit for bare-foot areas, play areas, or dog runs.

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.
