The parking lot sits a quarter-mile uphill from the strand, and the descent through coastal scrub prepares you for the peculiarity waiting below: patches of lavender-hued sand mingling with ordinary beige, most vivid where manganese garnet fragments concentrate near the waterline. You'll crouch to confirm it's real, fingers sifting through grains that look like crushed gemstones under the right slant of light.
“The only beach in California where manganese garnet deposits turn the shoreline shades of mauve and violet.”

Keyhole Arch dominates the southern end, a doubled sea stack pierced clean through by centuries of Pacific assault. At low tide you can walk beneath it, boots squelching in kelp-strewn sand, dodging the frigid surge that funnels through the opening. Photographers camp out two hours before sunset, tripods anchored against the wind, waiting for that five-minute window when the sun aligns perfectly with the aperture and sets the wet rock glowing.
The beach faces west with no shelter, so bring layers—the marine wind cuts through fleece by mid-afternoon. Driftwood logs offer makeshift seating above the high-tide line, and tide pools on the north rocks harbor ochre sea stars and hermit crabs. Swimming is dangerous here; riptides and shore break claim the unwary. You come for the geology, the arch, and the strange beauty of sand that refuses to behave like sand anywhere else.
