We are having the unique experience of RIDING through a healthy, living redwood tree. This Tour-Thru Tree is approximately 725 years old and at some time in the distant past, was scarred by fire. Because of its giant size, along with neighboring trees, was spared when the area was logged in 1967. The tree is 15 feet (4.5 m )in diameter at eye level. It is about 90 ft. (27 m) tall to the point where the top was blown off. Side branches give it an overall height of 164 ft. (50 m).
