Tunnel Log

Sequoia National Park

Sequoia National Park is home to some of the largest living organisms on the earth, Giant Sequoia trees. Clustered in groves throughout the park, these trees can stand nearly 300 feet tall and can have a diameter of nearly 25 feet.

In addition to a trip to see the General Sherman tree (the largest tree in the world!) no trip to Sequoia National Park would be complete without a stop at Tunnel Log. Tunnel Log is one of the few places where visitors can truly take in the immense size and power of these trees up close and personal. Tunnel Log provides visitors the chance to drive through a downed sequoia tree!  How’s that for a destination?!

The tunnel was created in 1938 after an unnamed sequoia tree fell across Crescent Meadow Road. The tree was 275 feet high and 21 feet in diameter and was most likely over 2,000 years old when it fell.  The tunnel was cut in the log to make the road passable again, and stands today17 feet wide and 8 feet high. The tunnel remains as an example of the sheer size and strength of the sequoia. Visitors can gain a whole different perspective of these trees simply by driving through Tunnel Log. 

When to Go:

Sequoia National Park is open year-round and offers a different experience each time of year. The best time to visit is in the late spring and early summer when the wildflowers are in bloom.
