About Giant Forest Grove
Giant Forest Grove is one of the largest sequoia groves, covering about 2,107 acres. It is in the Kaweah River Watershed region situated between 5,154 - 7,816 feet elevation at 36.56531°N. It is managed by Sequoia-Kings Canyon National Park. Giant Forest is located on a rolling plateau between the merging canyons of the Marble Fork and the Middle Fork of the Kaweah River. It is home to some of the most exceptionally large sequoia trees including the General Sherman Tree - the world’s largest living tree - as well as many other iconic sequoia trees. As such, Giant Forest is a large attraction for the Sequoia-Kings Canyon (SEKI) National Park and is a heavily visited area. The resilience and restoration of this grove is a high priority to SEKI National Park. Controlled burns have been extensively implemented in Giant Forest since 1979 in an effort to maintain wildfire resilience and a healthy ecosystem. Mature giant sequoias have never been logged in this grove.
