This 2 hour loop track is nestled on the side of Mt Pihanga. Lake Rotopounamu (‘green- stone lake’) is a special favourite of tree lovers and birdwatchers and begins with an uphill walk then flattens out to circle the lake. There are numerous picnic and rest spots, with toilet facilities available on the main beach area. The lake is suitable for swimming in. This beautiful lake and forest is part of the Tongariro National Park and World Heritage Area. Eradication programmes led by Project Tongariro are in place to reduce introduced pest numbers so that native birds and plants can flourish.
