The beach runs so long that naming a single focal point feels arbitrary. Some stretches front low-rise condos; others back onto scrubland where juniper and mastic bushes grow in wild tangles. You'll hear Italian, German, French—Costa Rei pulls a pan-European crowd, families who return year after year for the reliable sun and gentle surf. The sand is fine and nearly white, squeaking faintly underfoot when dry.
“Sardinia's longest uninterrupted sandy coast, where sheer scale ensures personal space even when the resorts fill to capacity.”
Sunset reflecting on wet sand
Wade into the shallows and the water shifts from mint green to deeper blue as the seabed drops. Windsurfers rig up when the afternoon breeze arrives, their sails bright against the horizon. Paddleboarders trace lazy arcs parallel to shore, and you'll spot the occasional kitesurfer farther out where the wind blows unobstructed. The sea bed is mostly sand, though patches of posidonia sway in the current near the rocky outcrops that interrupt the beach every few hundred meters.
By late afternoon, the light softens and the beachfront cafés start prepping aperitivo service—Aperol spritz, bowls of olives, small plates of fried calamari. Families gather their gear as the sun sinks lower, casting long shadows from the umbrellas. Walk north or south and you'll find quieter sections where the only company is shorebirds poking the wet sand for invertebrates. The mountains inland turn violet as dusk settles, and the first stars prick the deepening sky.
