Originating from Lake Tarawera, the river flows over a rhyolitic lava flow from Mount Tarawera before plunging into the impressive waterfall. Visitors can access the base of the falls via a well-maintained track provided by the Department of Conservation NZ, offering a picturesque view of the cascading water.
A distinguishing feature of Tarawera Falls is the underground river that flows from its base. When it rains, the river vanishes about 30 meters back from the clifftop into flooded caves in the lava, only to reappear further downstream. This intriguing natural phenomenon enhances the attraction of the waterfall, making it a must-visit spot for travelers exploring the Bay of Plenty region.
