Every New Year, people mostly from Inanda township, near the coastal city of Durban, trek barefoot about 80 kilometres (50 miles) and set up camp at the foot of the peak. They believe that on its heights, itinerant preacher Isaiah Shembe received divine instructions to found the church.
Created in 1913 and also known as the Nazareth Baptist Church, the institution is one of the largest African traditionalist churches, combining Christianity with the Zulu culture. Followers revere Shembe, who died in 1935, as their prophet.
After arriving at the base of the mountain, worshippers clamber up and down twice a day, led by women followed by men carrying sticks and then children.
They also tend wayside graves, laying flowers. It takes about an hour to reach the top, where they listen to sermons dedicated to peace and unity.
Yet while the church has many millions of followers, it is plagued by divisions and court disputes over leadership and access to the mountain. A larger faction today climbs a different mountain. Due to the tensions, police have been on duty at Nhlangakazi.
