5The Sardine Run, South Africa

The Sardine Run gained its worldwide reputation with the release of “Blue Planet” as everyone saw the billions of sardines migrating up the Eastern Coast of South Africa. Shoals of up to 15 km long attract hungry seabirds, whales, sharks and, of course, dolphins don’t hesitate to get in on the action.

Divers can be dropped in the middle of the feeding frenzy for a chance to see some of the 18,000 dolphins which chase sardines every year. Divers not only get to see them in impressive numbers but also witness the mammals showing off their intelligence as they cooperate to hunt the huge shoals. When to Go: May to July for the Sardine Run, though dolphins are present year round Type of Dolphins: Bottlenose and common dolphins
