Located at the most southern point of Africa,Cape Agulhas is both a cool place to go to and a beautiful tourist destination. Since it is also the official border between the Atlantic Ocean and the Indian Ocean. The water here is warm like the Indian Ocean and I would recommend a visit for casual swimmers.
The nearby Cape Agulhas Lighthouse, which is over 150 years old, is a destination of its own. Its history and spectacular view are two reasons to visit the lighthouse. Cape Agulhas is definitely worth a visit and is one of my coolest places in South Africa.
