Counting the waves…
Cala Sinzias occupies a wide bay on the Costa Rei stretch, its sand paler and finer than most of the south coast. The beach runs long and open, dunes rolling behind you, shallow water extending so far offshore that the horizon seems to begin in the middle distance. Families colonize the shallows, where toddlers splash and build castles without risk. The sand underfoot is compacted and smooth, easy walking even at midday. The water is transparent in a way that feels technical—engineered. You see your toes magnified on the white bottom, watch tiny fish navigate between your ankles, count ripples in the sand three meters out. The color shifts as you wade deeper, from silver to mint to a pale turquoise that photographers chase. Snorkelers explore the rocky points at either end of the bay, where the bottom finally drops and Posidonia begins. Umbrellas cluster near the access points, but the beach is wide enough to find solitude if you walk. Dune vegetation—juniper, mastic, wild lilies—holds the sand in place and muffles the sound of the parking lot. Late afternoon, when the angle of the sun flattens and the water goes glassy, the whole scene looks overexposed, bleached. You'll need sunglasses. You'll need to reapply sunscreen twice as often as you think.
