Doubtless River
# Doubtless River

The Doubtless River is a river of northern Canterbury, New Zealand. A tributary of the Doubtful River, it rises south of Mount Boscawen and flows southward through the Lake Sumner Forest Park to join that river 2 kilometres (1.2 mi) east of Phantom Flat.

The New Zealand Department of Conservation maintains a backcountry hut near the junction of the Doubtless and Doubtful Rivers.
