Chandlers Creek rises in the Marengo State Forest, about 7 kilometres (4.3 mi) northwest of Mount Hyland, below Thunderbolts Range, within the Great Dividing Range, east southeast of Glen Innes. The river flows generally to the northeast then north northwest through parts of the Guy Fawkes River and Chaelundi national parks, joined by two minor tributaries before reaching its confluence with the Boyd River at Louis Point, a locality on the Old Glen Innes Grafton Road west of Coutts Crossing.[2] The river descends 1,100 metres (3,600 ft) over its 64 kilometres (40 mi) course.[1]
