KwaZulu-Natal is South Africa's most geographically varied province, stretching from the warm Indian Ocean coast up through the Natal Midlands to the high peaks of the Drakensberg Mountains. It is also historically the heartland of the Zulu nation, and that history is present everywhere.
Durban is the provincial capital and the biggest city — a port city shaped by its Indian community, with excellent curry restaurants and a long beachfront. North of Durban, the Dolphin Coast runs up toward the game reserves of iSimangaliso Wetland Park and the St Lucia Wetlands, a UNESCO World Heritage Site.
The Drakensberg occupies the western edge of the province, rising to over 3,000 metres along the Lesotho border. The Cathedral Peak, Giant's Castle, and Royal Natal areas offer exceptional hiking and San rock art sites. A road trip from Durban up into the mountains and back is one of the most rewarding routes in the country.
The battlefields of the Anglo-Zulu War — Isandlwana and Rorke's Drift — and the Anglo-Boer War are in the northern Midlands and well worth a day with a guide if history interests you. Hluhluwe-iMfolozi Park, Africa's oldest nature reserve, offers the best chance of seeing rhino anywhere on the continent.
The province rewards slow travel. The distances are real — Durban to the Drakensberg is a three-hour drive — but the variety is unmatched in South Africa. You can swim in the warm Indian Ocean in the morning, be among elephants at a game reserve by afternoon, and wake up in mountain mist the next day. Most people see KwaZulu-Natal through Durban alone; that's a missed opportunity.
