Bring bold contrast and natural texture to your landscape with our premium Kendall Gray Lava Rock. This lightweight volcanic rock features a deep charcoal-black hue and a porous, rugged texture that enhances both residential and commercial outdoor spaces in Marin, Sonoma, Napa & Solano areas.
 
Whether you're designing pathways in Novato, building planter beds in Petaluma, constructing fire pit surrounds, or large-scale xeriscapes in Napa, our various size options let you choose the right rock for your project’s scale and aesthetic. Smaller sizes like 5/16" or  3/8"offer tighter compaction and are ideal for walkways and top dressing, while ¾" and 1½" sizes provide striking texture and coverage for decorative and structural uses.
