This paved loop through Mariposa Grove delivers the giant sequoia experience without the hiking commitment. You'll circle past the Grizzly Giant, the park's largest sequoia, and walk through the California Tunnel Tree, all on flat ground that takes most people under two hours.

Overview
The Grizzly Giant Loop cuts through one of the Sierra's most famous sequoia groves on terrain that's accessible to nearly everyone. The entire route is paved and relatively flat, winding between ancient trees that predate the Roman Empire. This isn't wilderness hiking — it's more like walking through a living museum where the exhibits happen to be 2,000-year-old trees.
The grove sits at around 5,400 feet elevation, high enough to support giant sequoias but low enough that snow doesn't linger all winter. The trees here survived logging in the 1800s and now anchor one of Yosemite's most visited areas. The trail connects the grove's celebrity trees: the Bachelor and Three Graces, the towering Grizzly Giant, and the California Tunnel Tree with its car-sized opening.
What to Expect
The loop starts from the arrival area and follows paved paths with gentle grades throughout. You'll encounter interpretive panels explaining sequoia ecology — how these trees survive fires, why they need burned ground to germinate, and how they can live for millennia in the Sierra climate.
The Grizzly Giant stands 209 feet tall and measures 30 feet across at its base. Age estimates put it between 1,900 and 2,400 years old, making it ancient when the California missions were founded. The tree's massive lower branches are larger than most entire trees, and its girth becomes clear when you see people standing at its base for scale.
The California Tunnel Tree was carved in 1895, part of the era when tourist attractions meant cutting holes through living giants. The opening is large enough to walk through, though the tree continues to thrive despite the modification. Near the end of the loop, the Bachelor and Three Graces cluster showcases how sequoias often grow in family groups.
Tips & Logistics
The shuttle system runs from early March through late November, with buses departing from the Welcome Plaza every few minutes during peak times. The plaza has 300 parking spaces, but they fill early in summer and fall. Arriving before 9 AM or after 4 PM improves your odds of finding a spot.
If you have a disability placard, you can drive directly to accessible parking at the grove itself, bypassing the shuttle entirely. Wheelchair-accessible sections cover the main highlights, including the Grizzly Giant.
Winter changes the logistics significantly. When snow closes Mariposa Grove Road, usually December through March, the shuttle stops running and cars can't reach the Welcome Plaza. The grove remains open to hikers, snowshoers, and cross-country skiers willing to cover the additional 2 miles each way from the South Entrance gate.
Water is available at the arrival area during summer only. In winter, the only water source is back at the Welcome Plaza. Restrooms operate year-round at several locations throughout the grove, though winter facilities are limited to pit toilets.
The trail works for families with young kids and anyone looking for an easy introduction to Yosemite's natural features. Most people complete the loop in 1-2 hours, but the benches and flat terrain make it easy to take breaks and extend the experience.
