River Rock vs. Lava Rock: Which Is Right for Your Landscape?
Two Popular Choices, Very Different Looks
River rock and lava rock are two of the most popular decorative landscaping stones—but they serve different purposes and create very different aesthetics.
River Rock: Natural and Smooth
River rock is naturally tumbled stone with smooth, rounded edges. It comes in a range of sizes and earth tones.
Best uses:
- Dry creek beds and drainage channels
- Garden borders and decorative beds
- Around water features
Popular options include 1-1.5" River Rock and 1x4 River Rock for larger coverage.
Lava Rock: Bold and Lightweight
Lava rock is volcanic stone—lightweight, porous, and available in striking red or black colors.
Best uses:
- Decorative ground cover
- Fire pit surrounds
- Xeriscaping and low-water landscapes
Choose between 3/4" Black Lava for a modern look or 3/4" Red Lava for warm contrast.
