So you want to drive through a tree? Well, you've got options. (At least for now. Since no new drive-through trees will be created any time soon, for obvious environmental reasons, the existing ones are maybe the last of their kind.) There are actually three trees in the vicinity of Redwood National and State Parks whose trunks are wide enough to accommodate a car. The Chandelier Tree, at the Drive-Thru Tree Park, may be the most well-known and most frequently photographed; pay your $5 and get behind the wheel. The Tour Thru Tree, near Klamath, is the other tree with a human-constructed tunnel. The only organically occurring drive-through tree in the area is the Shrine Tree in Myers Flat, on Avenue of the Giants. The opening in this tree was primarily nature-created—though at this point it's held together with some human help. Shrine also has a fallen tree with a drive-up ramp, a stump you can walk through, and a couple of playhouses carved from redwoods.
In the tiny hamlet of Leggett in California's Humboldt county you can drive through the Chandelier Tree. This tree is a 315 foot tall coast redwood tree with a 6 foot wide hole cut through its base to allow a car to drive through. The hole was carved in the 1930s. Take some time to explore all the natural wonders of the scenic Avenue of the Giants including a house made out of a giant redwood (Tree House) and the Immortal Tree, the oldest redwood (950 years old) in the forest. Impressive!
