Tunnel Log

Overview

Tunnel Log is exactly what it sounds like: a giant sequoia that fell across the road, then was tunneled so you can drive right through. It’s a quick, fun novelty and one of the park’s most photographed stops—perfect for a souvenir shot and a sense of the trees’ scale.

A bit of history

A massive sequoia—about 275 feet tall and roughly 21 feet in diameter—fell across Crescent Meadow Road in 1937 due to natural causes. Rather than remove it, a tunnel was carved in 1938, reflecting an earlier era of park management that leaned into memorable visitor experiences. The tunnel opening is about 17 feet wide and 8 feet high, with a bypass for taller vehicles.

Where it is & how it works

You’ll find Tunnel Log on Crescent Meadow Road in the Giant Forest area, about 0.5 miles past Moro Rock. The approach is an active traffic zone: most visitors queue single-file, take a quick turn through, and grab a photo. There are only small paved pull-outs nearby, so expect brief waits while others stage their shots. If your vehicle is taller than 8 feet, use the bypass road and walk back for photos.

Season and access

Crescent Meadow Road generally opens in late spring (often by the Wednesday before Memorial Day) and closes when snow makes it impassable. On busy summer weekends, the road is often closed to private vehicles during the day; plan to use the park shuttle in those periods. Always check current road and shuttle status before you go.

Best time to visit

• Go early—sunrise is your friend. You’ll beat the line and get softer light under the forest canopy.
• Weekdays are typically calmer than weekends. Late afternoon light can be nice but expect more people.
• In winter when the road is closed, you won’t be able to drive through; some visitors see it on foot when conditions allow.

Photo etiquette and safety

Keep setups quick so traffic flows. This is a tight roadway with cars and pedestrians weaving around a popular shot—be courteous and alert. Pets may be with you on paved roads here; keep them leashed and out of traffic.

Pair it with

Combine Tunnel Log with Moro Rock just up the road and the Crescent Meadow area beyond. It’s an easy add-on to any Giant Forest itinerary.

Is it worth it?

Yes—if you treat it as a five- to ten‑minute novelty stop. It’s fun, memorable, and very “Sequoia,” but not a half‑day activity. Time it right and you’ll be in and out with a grin and a great photo.
