For many, a trip to the Mariposa Grove of Giant Sequoias is a once-in-a-lifetime experience. Visitors often compare the Grove to a spiritual cathedral, where they stand in awe of the sheer grandeur of the ancient sequoia trees.  It is hard to comprehend, but if one of these trees topples, it would take 1,000-3,000 years to grow a similar tree in its place. The project to restore Mariposa Grove is an ambitious, multiyear effort to preserve these majestic trees and reverse 150 years of development by balancing visitor needs with ecological protection.

Groundbreaking: June 30, 2014

The project officially broke ground on June 30, 2014 during a joint National Park Service and Conservancy celebration for the 150th anniversary of the Yosemite Grant Act. Park ecologists, wildlife managers and others are working together to mitigate future impact to the trees, restore the grove ecosystem, protect wildlife and create an exceptional experience for park visitors. The Mariposa Grove is expected to reopen in early November 2017.

Your support is restoring Mariposa Grove today, to ensure that future generations will be inspired by this special place and its magnificent giants.

The Mariposa Grove is not just a sanctuary for people; it’s also an important refuge for a diverse assemblage of animals that rely on the Grove’s protected status.
