The boardwalk along Trouville's beach is the symbolic centre of the town. A line of wooden planks runs for nearly two kilometres above the sand, fronted by a row of small painted bathing huts that families rent for the summer. Belle Époque villas, the casino, and the Cures Marines spa form a backdrop on the inland side.
The promenade is busiest in late afternoon and early evening, when families fill the cafes that line it. Walk the full length, then sit at a beach cafe with a glass of cider and watch the tide come in.
