Mossel Bay is a harbour town on the Garden Route in South Africa’s Western Cape Province. It’s known for the wide Santos Beach and the 19th-century Cape St. Blaize Lighthouse, which offers bay views. The Bartolomeu Dias Museum Complex includes the Maritime Museum, the Shell Museum and botanical gardens. The Post Office Tree, a milkwood tree in the complex, has been used as a mail collection point since the 1500s.
