The approach is half the reward: a rutted dirt road through shoulder-high scrub, the air thick with the resinous scent of immortelle and rockrose, cicadas sawing in the heat. The cove opens suddenly—a shallow crescent of coarse sand and smooth pebbles cupped between low granite headlands. The water is absurdly transparent, shading from pale aquamarine in the shallows to deep sapphire where the seabed drops away just beyond the cove's mouth. On windless days the surface is so still you can see individual rocks on the bottom three metres down, each stone rimmed with a halo of rippled sunlight.
“While Campomoro's main beach absorbs the masses, Canuseddu remains the secret the tower can see but most visitors never seek.”

Snorkeling here is less about fish density and more about clarity and topography. The left headland extends underwater in a tumble of boulders colonized by purple sea urchins and orange encrusting sponges; damselfish and rainbow wrasse patrol the crevices, and if you hover motionless long enough, octopus will sometimes emerge from the rubble to investigate. The seabed alternates between sand patches and posidonia meadows, each transition marked by a shift in the light and the species you encounter. Visibility routinely exceeds ten metres, especially in morning calms before the afternoon libeccio kicks up chop.
The beach itself is small—space for perhaps two dozen people before it feels crowded—and utterly lacking in services. No bar, no umbrellas, no lifeguard. You carry everything in and out, and that effort curates the crowd. Most days you'll share Canuseddu with a handful of snorkelers and a few locals who know the cove from childhood.
