1. Grande Plage
This is the postcard image of the city, a strip of golden sand dominated by the striped tents and the imposing silhouette of the Hôtel du Palais. It is undeniably crowded in summer, a patchwork of towels and umbrellas that leaves little room for solitude, but the energy is part of the appeal. The waves here are strictly zoned—flags clearly separate swimmers from the surfers who drift in the lineup, a necessary order in the chaos of high season.
Even if you do not swim, the beach is a theater of local life. You see the surf schools drilling beginners in the whitewash and older locals swimming their daily laps regardless of the water temperature. It is the most accessible of Biarritz attractions, sitting right at the foot of the casino and the main shopping streets, which makes it easy to dip in for an hour between other activities.
High tide can swallow most of the sand, pushing everyone up against the seawall, so checking the tide charts is essential if you plan to sunbathe. The promenade above offers a perfect vantage point to watch the tide roll in, often crashing spectacularly against the sea walls during winter storms.
