The Tane Mahuta tree is about 2000 years old (Thats old) But there is another tree which is called Te Matua Ngahere that ages to about 2500 - 3000 years old.
I also think it will be a nice time to spend time with the family and explore the forest also learning new facts. Fun fact: Waipoua is a ancient green world of towering trees and rare birds.
Sorry for late post been doing different things ( S,L,J )
