Popple Peak, Mountain summit on the Lesotho–South Africa border

Popple Peak is a 3,331 m summit in the Drakensberg, on the South Africa–Lesotho border; its top lies in Lesotho. It rises about 300 m above the surrounding escarpment and stands roughly 4 km southeast of Njesuthi. The peak is also known as Khoko-Ntso.

Barry Anderson, Des Watkins and John Poppleton reached the summit in 1946. A thunderstorm came up on arrival, and Poppleton, fearing for his safety, left the top. Anderson sent the survey to the Surveyor General with the height and the name "Popple Peak", after Poppleton.

The peak also carries the Sesotho name Khoko-Ntso (or Khoko-Ntšo), used alongside the Afrikaans Popplepiek. Its summit lies on Lesotho territory, while the mountain straddles the border watershed. The name Popple Peak, given by Barry Anderson, honours John Poppleton, one of the three climbers who reached the top in 1946.

The summit lies on the Lesotho–South Africa border, with the top itself inside Lesotho; the Njesuthi summit is about 4 km to the northwest. The peak rises roughly 300 m above the surrounding escarpment, so approach and descent cross steep, exposed ground. Thunderstorms build quickly here, as they did in 1946, so plan to be off the summit early.

The peak belongs to an exclusive group called Khulus: mountains above 3,000 meters that stand more than 1 kilometer away from other similar elevations. This rare classification sets it apart on the regional mountain landscape.
