You cannot drive a car through a living Sequoia tree in a National Park, as this is now considered environmentally damaging. However, you can still drive through the "Tunnel Log" in Sequoia National Park. This is a massive Giant Sequoia that fell across the road due to natural causes in 1937; a tunnel 17 feet wide and 8 feet high was carved into the trunk to allow vehicles to pass through. It is a very popular photo spot and remains open to the public during the summer months. There are also a few privately owned "drive-through" trees in Northern California—specifically Coast Redwoods, which are taller and more slender than Sequoias. These include the Chandelier Tree in Leggett, the Shrine Drive-Thru Tree in Myers Flat, and the Tour Thru Tree in Klamath. While these are popular tourist attractions, conservationists emphasize that these modifications are relics of an older era of tourism and that modern forest management focuses on preserving the trees in their natural, unaltered state.
