Cayenne is easy to see on foot in one day. The center of the action is the Place des Palmistes, lined with colonial timber-fronted buildings and full of palm trees. To its west, Place Léopold Héder (aka Place Grenoble) is the oldest part of the city. After a siesta, cruise Av du Général de Gaulle, the main commercial street, to experience Cayenne at its bustling peak. La Place des Amandiers near the coast is the place to go to relax with pétanque (bowling) and dominoes.
