Notes: Tour Thru Tree is located at 430 California State Route 169 (Klamath Glen Road) in Klamath, California 21 mi (34 km) south of Crescent City. Tour Thru and neighboring trees were spared when the area was logged in 1967.
In May 1976, retired United States Air Force Major and former Del Norte County supervisor Harold A. Del Ponte hired two nephews, one an engineer and the other a tree faller, to carve a 7.33 ft (2.23 m) wide and 9.50 ft (2.90 m) tall tunnel, large enough for automobiles, through the trunk of Tour Thru. They completed the job, using a 7 ft (2 m) long chainsaw, in just under two days. As compensation, Del Ponte offered his nephews $600 cash up-front or half of the tourism proceeds perpetually. Never anticipating that Tour Thru Tree would become a popular tourist attraction, the men opted for cash.
Tour Thru, which appears in a television commercial, is the newest and second most-popular of the three drive-through coast redwoods: as many as 60,000 vehicles visit the tree each year. Although Chandelier is more-popular, Tour Thru accommodates larger vehicles. Tour Thru Tree Park also offers picnic tables, a unique redwood restroom, a gift shop, and (in a field across the street) a mob of emus (Dromaius novaehollandiae). Tour Thru Tree Park is open year-round. Call 707-482-5971 for seasonal hours, entrance fees, and more information.
