🔒 Local Secrets

📧
Post Office Tree — You can still post a letter from the boot-shaped letterbox at this ancient milkwood tree. Your postcard gets a special Dias Museum stamp.
🌊
Pinnacle Point caves — Archaeological sites on the St Blaize Trail contain 164,000-year-old evidence of early human behaviour. Some of the oldest evidence of symbolic thinking on Earth.

Seal Island boat trip — If shark diving is too extreme, a boat trip to Seal Island (R450pp) gets you close to thousands of Cape fur seals and frequent shark sightings from the boat.
Mossel Bay's attractions blend rich maritime history with thrilling natural encounters.
