The river Adurant ran from the southern Blue Mountains into the river Gelion, marking the southern boundary of Ossiriand.

According to Karen Wynn Fonstad's The Atlas of Middle-earth, it was over one-hundred and fifty miles in length.[1]

The small island of Tol Galen lay between its banks.[2][3]


The word Adurant means "Double-course" in Sindarin, referring to a parting of the river about the isle of Tol Galen.[4]
