Except for Bagaud Island, the Hyères archipelago are the largest islands on the Provençal coast with areas of 3,158 acres (1,278 ha) for Porquerolles, 2,473 acres (1,001 ha) for Le Levant, and 1,549 acres (627 ha) for Port-Cros. The relief of these three islands exceeds 328 ft (100 m) in altitude, reaching 643 ft (196 m) in Port-Cros, the most rugged, 465 ft (142 m) in Porquerolles and 459 ft (140 m) on Le Levant Island. Their rather marked topography leaves room for a significant and cultivated plain only in Porquerolles.
