The full circuit takes about two hours and passes several beaches suitable for picnics and swimming in summer. The lake covers one square kilometre, reaches nine metres in depth, and has no permanent visible outflow. Access is from State Highway 47, 11 km from Tūrangi.

About Lake Rotopounamu and the Track
Lake Rotopounamu occupies a crater on the western flank of Mount Pihanga. The lake is fed by four tributary streams and usually has no visible surface outflow, with water escaping below ground. Its name derives from the Māori words “roto” (lake) and “pounamu” (greenstone). The surrounding forest includes podocarp, broadleaved and beech species together with wetlands that support a range of native ecosystems.
The track begins opposite the car park and climbs gently to a junction. Walkers can complete the full loop by turning right and following the path past Five Minute Beach, Long Beach and Ten Minute Beach before returning via the northern shore. Several beaches provide spots for rest or swimming during warmer months. The shorter option from the junction leads directly to Ten Minute Beach in about 20 minutes.
Birdlife thrives thanks to ongoing pest control by Project Tongariro in partnership with DOC. Species present include toutouwai (North Island robin), tītīpounamu (rifleman) and kōmiromiro (tomtit), along with more common forest birds such as kererū, tūī and pīwakawaka.
Access and Safety
The car park lies on the south side of Te Ponanga Saddle on State Highway 47. Visitors must take care crossing the busy road to reach the track start. The route is suitable for families and offers a pleasant break for travellers between Taupō and the central park attractions. Allow extra time in winter when conditions may be cooler and wetter under the forest canopy.
Biosecurity and Conservation
Rotopounamu is part of a World Heritage area where sustained pest control protects native biodiversity. Visitors are asked to arrive with clean footwear and equipment to avoid introducing weeds or pathogens. The lake and forest are managed to maintain water quality and habitat values for the species that live there.
What Visitors Often Say
A peaceful and scenic short walk through beautiful native bush with several nice beaches for a break or swim. The track is easy enough for most ages and offers good birdwatching opportunities.
Great stop-off point when travelling through the area. The lake is clear and the forest feels mature and tranquil. The loop is straightforward and well worth the small detour from the highway.
