The best view of the Morro castle, one of the symbols of Havana, is from the Malecón in the 4th zone, as the front of the Castillo de San Salvador de la Punta is the closest point to the castle at the entrance channel of Havana Bay. Zone 4 is also the most green area in the old town.
Close to the Malecón, there is the Callejón de Peluqueros (Alley of the Hairdressers) that is one of the vital spaces in Old Havana, where you will find many restaurants and cafés, able to cater to every palate.
