Bahorok or Bohorok is a subdistrict of Langkat Regency. Its capital is Bohorok town, and Bukit Lawang is a major local tourist attraction for viewing orangutans.
The Bohorok river, which is a tributary of the Wampu River, joins the Wampu in the subdistrict.
According to legend, a Karo of marga Peranginangin, submarga Sukatendel was hunting and found a child in some bamboo. The child was given to a childless woman to raise. The area where the child was found eventually became Kuta Buluh. When that child grew older, he married a woman of Sukatendel village.
He had five children, the middle being Dewa Perangin-angin. Dewa Perangin-angin converted to Islam, in order to marry Paga Ruyung of Deli Tua.
They had three children, Sutan Jabar, Sutan Husin and Putri Hijau. Sutan Husin was in a dispute with his brother, Sultan Jabar, so Slutan Jabar went to Malacca, while Sutan Husin following the Wampu river upstream, and stopped to rest where it met another river (the Bohorok). Eventually he built a house at this point. One day, while on a hunting trip, he climbed the hill from the river, and finding an unknown sweet-tasting fruit tree at the top named it Buah Huruk (or fruit that is atop the hill in Karo language).
