What Is the Tunnel Log?

The Tunnel Log is a fallen sequoia tree that crosses Crescent Meadow Road. It fell in 1937 and stood at 275 feet with a 21-foot diameter at its base before falling. During the Great Depression in the 1930s, many men had trouble finding work. To help combat the work issue, President Franklin D. Roosevelt created the Civilian Conservation Corps (CCC), which helped primarily young, unmarried guys obtain conservation work. Instead of moving the tree, a team of CCC workers carved the tunnel in the fallen sequoia tree in 1938, creating what is known as the Tunnel Log.

Driving buggies and cars or walking through the tunnel tree became useful for continued travels through the forest.

How to Visit the Tunnel Log

You can drive through the tunnel tree when you visit the Sequoia National Park. Visiting the park requires no reservation, but if there are specific activities you want to do, you may have to schedule those in advance. Regardless of your plans, you must pay an entrance fee to visit the national park. Once you are in the park, you can continue on your way to the Tunnel Log or hiking trails.

To get to the Tunnel Log, drive down Crescent Meadow Road. You will reach it after you get about half a mile past Moro Rock. Your vehicle must be less than 8 feet tall to drive through the Tunnel Log. If it is taller, you can take the bypass instead and walk back to the tunnel tree.

With how massive sequoia trees are, driving through the Tunnel Log offers an extraordinary experience that you and your family will not soon forget.

What to Expect

If you want to drive through the Sequoia National Park car tunnel, visit the park during the warmer seasons, like late spring, summer and early fall. Crescent Meadow Road, the road leading to the tunnel tree, is only open during the warmer months since it becomes impassable in the winter due to snow. If you visit during the winter or early spring, the area is only accessible by hiking, snowshoeing or skiing.

Regardless of what you do, pack the necessary supplies and dress appropriately for the weather. If driving, make sure to prep your vehicle and ensure it can handle various terrains.
