Mariposa Grove Yosemite activities consist almost exclusively of hiking and viewing these magnificent trees. In spring, summer and fall (May to October) you can also take a one-hour tram tour.

Hiking and Highlights

See both the lower and upper groves on a moderate 5 to 6-mile hike or just the lower grove on an easy 2.2-mile roundtrip hike. There are certain trees you must be sure to see!

  • Grizzly Giant
    This tree is estimated as being 2,700 years old, the oldest tree in the grove. Simply wondrous in its beauty, the Grizzly Giant is the star of the grove, measuring 30 feet in diameter at its base and over 90 feet in circumference.
  • California Tunnel Tree
    Just past the Grizzly Giant is the only living tree in Yosemite with a tunnel drilled through it. You can walk through this marvelous Sequoia while marveling at how small it makes you feel in comparison.
  • Wawona Tree
    In 1881 a tunnel was carved into the trunk of this Sequoia. It was renamed “The Fallen Tunnel Tree” as it was toppled by a storm in 1969. You can still view its awesome size, even though it now lies on the ground.
  • Washington Tree
    This tree has the distinction of being the largest tree in the grove.
  • The Fallen Monarch
    Since Giant Sequoias don’t decay rapidly, you can still view this Giant Sequoia that fell over three hundred years ago.
  • The Telescope Tree
    Repeated fires created a tree with a completely hollow trunk. You can walk inside and look up at the sky.
  • The Columbia Tree
    At 285 feet high, this is the tallest tree in Mariposa Grove.

Fun Facts

Yosemite Mariposa Grove was first discovered by Galen Clark, a homesteader in Wawona, when he happened upon these Giant Sequoias. He named the grove after the California county where the grove is located.
