Overview

If you’re exploring Yosemite National Park, the California Tunnel Tree is one of those iconic stops you absolutely can’t miss. Towering above you, this massive sequoia invites visitors to experience the sheer scale and beauty of California’s ancient forests. The trail leading to the Tunnel Tree is family-friendly, short, and perfect for a leisurely stroll through some of the oldest trees on the planet. Whether you’re snapping photos, taking a moment to breathe in the forest air, or sharing the experience with kids, this stop is a highlight of any Yosemite adventure.

The California Tunnel Tree has a fascinating history. Originally, tunnels were carved into several giant sequoias in the late 19th and early 20th centuries to allow horse-drawn carriages and later automobiles to pass through, creating a unique attraction for early tourists. Unlike other tunnel trees, this sequoia remains a pedestrian-friendly marvel. Walking through the tunnel connects visitors with Yosemite’s history while highlighting the grandeur of these ancient trees, some of which have been standing for more than 1,800 years.

California Tunnel Tree Plan

Yosemite National Park is massive, with over 750,000 acres of granite cliffs, waterfalls, meadows, and forests. Since we only had a day or two, planning our route was essential. We made sure to prioritize Yosemite Valley, Glacier Point, and Mariposa Grove, where the California Tunnel Tree is located. Stopping there let us see one of the park’s most famous sequoias without taking on a long, strenuous hike. We also explored the nearby Grizzly Giant and other giant sequoias, which made our visit feel truly complete.

Getting There

Location

Yosemite National Park is located in the Sierra Nevada Mountains of California. The Mariposa Grove of Giant Sequoias, home to the California Tunnel Tree, is near the park’s south entrance, accessible from Highway 41. The nearest town for lodging and supplies is Mariposa, California, just a short drive from the grove. GPS coordinates and park signage make it easy to find, and plenty of parking is available near the trailhead for visitors.

Best Time to Go

The California Tunnel Tree is a great stop year-round, but the best times to visit are spring and fall. Spring brings blooming wildflowers along the forest trails, while fall offers crisp air and golden foliage. Summer is busy but still rewarding, with long daylight hours for exploring. Winter can be quieter, though snow may close some roads or require chains for your vehicle. Weekdays are typically less crowded than weekends, making for a more peaceful experience.

Who Can Go?

This trail is beginner-friendly and accessible for families, seniors, and casual hikers. The path to the California Tunnel Tree is mostly flat, and the tunnel itself is low enough for a walk-through photo opportunity but easy to navigate. Wheelchairs or strollers may be limited in some sections, but the grove has accessible paths nearby for those with mobility challenges. Kids especially love the novelty of walking through a tree, making it a memorable stop for all ages.

What You'll See

Along the short trail, you’ll encounter massive giant sequoias, including the California Tunnel Tree and surrounding giants like the Grizzly Giant. Forest wildlife such as deer, squirrels, and a variety of birds are commonly spotted, and seasonal wildflowers add vibrant color in spring. The trail provides both serene forest views and photo opportunities that showcase the sheer scale of these ancient trees. You might even spot the fallen sequoias, which reveal the incredible life cycle of these giants.

What to Bring & Wear

Comfortable walking shoes are a must, as the trail is dirt-packed with some uneven sections. Dress in layers, as forest temperatures can be cooler than in the open valley. Bring water, a camera, and sun protection for any exposed areas. Binoculars are helpful for spotting wildlife, and a small backpack can hold snacks, jackets, or any gear for a longer day exploring the grove.

Where to Go

Start at the Mariposa Grove Welcome Plaza, where you can access maps, shuttle information, and restroom facilities. From there, follow the short marked trail to the California Tunnel Tree. Nearby, explore the Grizzly Giant Grove Loop to see more ancient sequoias. If you have time, continue along the trails to the Faithful Couple and other historic sequoias in the grove. Each stop offers unique photo opportunities and perspectives of Yosemite’s oldest residents.

How Long Does it Take?

The walk to the California Tunnel Tree and back typically takes 30–45 minutes at a leisurely pace. If you want to explore the surrounding Mariposa Grove and nearby giant sequoias, plan for 1.5–2 hours. The trail is short enough for a quick visit but also rewarding if you take time to pause, photograph, and appreciate the forest.

Cost

Access to Mariposa Grove and the California Tunnel Tree is included with the Yosemite National Park entrance fee, which is $35 per vehicle for seven days. Annual passes and interagency passes are also accepted. Parking at the Mariposa Grove Welcome Plaza is free, and shuttles run seasonally to minimize traffic in the grove.
