Le Pecq's territory is astride the two banks of the Seine and includes a small island, Corbière. It is highly urbanized except for Corbière island, which is partially protected as a nesting zone for migratory birds. Until after the Second World War, there were swimming baths on the island. Le Pecq was famous for two other establishments related to water: a spa exploiting springs on St-Germain hill and a natural water swimming pool which was 100 metres long with sand beaches.
It borders the communes of Saint-Germain-en-Laye and Mareil-Marly in the west, Montesson and Le Mesnil-le-Roi (Carrières-sous-Bois district) to the north, Croissy-sur-Seine and Le Vésinet in the east and Marly-le-Roi and Le Port-Marly to the south.
