A guide to visiting Sequoia National Park Tunnel Log: Drive Through a Giant Sequoia

What is the Tunnel Log tunnel in tree?
The Tunnel Log is a massive sequoia that fell naturally across Crescent Meadow Road in the Giant Forest area of Sequoia National Park in late 1937. Instead of removing this colossal obstacle, park officials decided to carve a tunnel through it the following summer, creating a distinctive attraction that has captivated visitors for over eight decades.

How to get to tunnel log Sequoia national park map
During my visit, I took advantage of the free Sequoia Shuttle service that operates during the summer months. It’s an excellent option for those who want to avoid parking hassles or prefer not to drive on the winding mountain roads. The shuttle stops at all major attractions in the Giant Forest area, including the Tunnel Log.
If you’d like to experience the ultimate drive through a sequoia tree here are the directions to drive through tree sequoia follow these directions:
- From the Ash Mountain Entrance, drive up Generals Highway for about 16 miles.
- Turn right onto Crescent Meadow Road.
- Continue for about 3 miles until you reach the Tunnel Log.
Tip: If you’re visiting during peak season (June to August), use the shuttle service. It’s free, eco-friendly, and eliminates the stress of finding parking at popular sites.

Best Time to Visit the Tunnel Log
Based on my experience and conversations with park rangers, the best time to visit the Tunnel Log depends on your priorities:
- For fewer crowds: Early morning (before 9 AM) or late afternoon (after 4 PM) on weekdays.
- For best lighting for photos: Mid-morning or late afternoon when the sun isn’t directly overhead.
- For guaranteed access: Late spring to early fall when the road is open and free of snow.
I visited in July, and while it was busy, the shuttle service made it easy to access without worrying about parking. The weather was perfect – warm but not too hot, ideal for exploring the park.
Tip: If you’re visiting in winter, call ahead to check road conditions. Crescent Meadow Road can close due to snow.
Best Photo Spots for sequoia tree tunnel
As a photography enthusiast, I was eager to capture the perfect shot of the Tunnel Log. Here are some prime photo locations I discovered:
- The approach: Stand about 50 feet back from the tunnel entrance for a shot that captures both the massive fallen tree and the tunnel.
- Inside the tunnel: For a unique perspective, have someone take a photo from inside the tunnel as your vehicle passes through.
- The exit: Position yourself on the far side of the log to capture vehicles emerging from the tunnel.
- Bypass road view: For a different angle, walk up the bypass road for an elevated view of the Tunnel Log.
Tip: Bring a wide-angle lens if you have one. It helps capture the full scale of the fallen sequoia. (I didn’t bring one and that’s ok, there was a long line! so if you can go early)

My Personal Experience
Driving through the Tunnel Log is a must-do when visiting Sequoia National Park. As I jumped on the shuttle from Moro Rock, I saw the sheer size of the fallen giant was awe-inspiring. The tunnel itself is smooth and well-maintained, making for an easy drive-through.
What struck me most was the texture and color of the sequoia’s interior, visible as you pass through the tunnel. The rich reddish-brown hues and the intricate patterns of the wood grain tell a story of centuries of growth.
After a quick photo with the tree and of the tree. I explored on foot and walked back to explore the area. This allowed me to truly appreciate the tree’s massive scale and read the informational plaques that provide context about the Tunnel Log’s history and significance.
Tips for Visiting the Tunnel Log
- Arrive early: I got there around 8:30 AM and practically had the place to myself for about 30 minutes.
- Use the shuttle: The free summer shuttle service is convenient and reduces traffic in the park.
- Be patient: If you’re there during busy times, you might need to wait for a turn to drive through. Use this time to admire the surrounding forest or read the informational signs.
- Check your vehicle size: Most standard cars and SUVs can fit through the tunnel, but if you’re unsure, use the bypass road.
- Respect the environment: Stay on designated paths and don’t climb on the fallen log. The sequoia’s root systems are fragile.
- Bring water and snacks: There are no facilities immediately at the Tunnel Log, so come prepared.
- Combine with other attractions: The Tunnel Log is close to Moro Rock and the Giant Forest Museum. Plan to visit these on the same day.
- Look for wildlife: I spotted several marmots and deer in the area. Keep your distance and never feed wild animals.
- Take your time: Don’t rush through. Park your car and explore the area on foot after driving through.
- Capture the moment: Whether it’s a photo, video, or just a mental image, make sure to record this unique experience.
The Significance of the Tunnel Log drive thru sequoia tree
While driving through a tree is undoubtedly fun, the Tunnel Log represents more than just a quirky roadside attraction. It serves as a living (or in this case, fallen) history lesson about the park’s past and the evolution of conservation practices.
In the early days of national parks, attractions like the Tunnel Log were seen as ways to draw visitors and generate support for conservation efforts. Today, we recognize the importance of preserving these natural wonders with minimal human intervention.
The Tunnel Log stands in contrast to the famous Wawona Tree in Yosemite National Park, which had a tunnel cut through it while still alive and eventually fell in 1969. The Tunnel Log, having fallen naturally, allows visitors to interact with a sequoia without harming living trees.
