Tunnel Log is a fascinating feature in Sequoia National Park, known for its impressive size and unique history. This massive fallen sequoia tree, which measures about 8 feet in diameter, was cut through in the 1930s to create a tunnel that allows vehicles to pass right through it. The log fell during a storm in 1937, and instead of removing it entirely, park officials decided to make the most of it by carving out a passage. Today, visitors can drive their cars through this iconic landmark, making it a popular spot for photos and a fun experience for families exploring the park. The sheer scale of the log serves as a reminder of the incredible natural wonders found in Sequoia National Park.
