The Tyume Valley is situated in the Eastern Cape Province, inland from East London about 120 km is the town of Alice, where Fort Hare University is located. Just a few kilometers before reaching Alice is the turnoff for the Hogsback road that goes up the heart of the Tyume Valley to the village of Hogsback atop the Amatola Mountains. From Hogsback, you can look south and see the Tyume Valley.
