Thing to Do
Tunnel Log
Soon after the Moro Rock / Crescent Meadow Road was completed, a giant sequoia fell, blocking the roadway. The tree was too large to move, so workers carved a tunnel through it. Since 1935, people have been driving through Tunnel Log. Now you can join in on the novelty of driving through a fallen Sequoia. Vehicles taller than 8 feet (2.4 m) can use a bypass.
A different tree you can drive through: Tunnel Log is made of a fallen horizontal sequoia tree. Many who think of the living sequoia tree you can drive through is located in Mariposa Grove in nearby Yosemite National Park. However, the famous standing tunnel tree in Yosemite collapsed in 1969.

Winter Visits: To access this area in winter, you will need to hike, snowshoe, or ski into the area.
