About
Atwell Mill Grove offers a majestic encounter with some of Earth's largest living organisms. This stunning giant sequoia grove, nestled within Sequoia National Park, provides a more secluded and rugged experience compared to other, more heavily visited groves. Visitors can immerse themselves in a serene forest setting where ancient giants tower, creating an awe-inspiring atmosphere of timeless natural beauty.
The grove is home to several exceptional sequoias, including the Diamond Tree, which stands nearly 290 feet tall and is the largest in the grove. Other notable trees include the Dean Tree, ranking among the top 30 giant sequoias globally with a volume of over 32,000 cubic feet, and the Arm Tree, known for having the largest limb of any tree worldwide, measuring approximately 12 feet in diameter. The unique Atwell Tunnel Tree also offers a fascinating sight with its internal cavity large enough to "hold three Volkswagen Bugs." Hiking through the grove reveals not only these monumental trees but also the East Fork of the Kaweah River and diverse mixed-conifer forests featuring ponderosa pines, sugar pines, Jeffrey pines, white firs, and incense cedars.
Visiting Atwell Mill Grove is an unforgettable journey into the heart of an ancient forest, providing a profound sense of scale and natural wonder. It’s a perfect destination for those seeking tranquility, impressive photographic opportunities, and a deep connection with nature away from the main park crowds. The challenging drive to the grove only enhances the feeling of discovering a hidden gem, rewarding adventurers with unparalleled views and a unique perspective on these magnificent trees.

Atwell Mill Grove, also known as the Skinner Grove of Big Trees, has a history intertwined with early California settlement and conservation efforts. The grove was originally home to a sawmill, Atwell Mill, built in 1879. This mill processed giant sequoia logs into lumber for local homes and shingles. The property eventually came into the possession of A.J. Atwell and later D.E. Skinner, who donated the land to the Department of the Interior. Though initially excluded, Atwell Mill Grove became part of Sequoia National Park with the park's expansion on October 1, 1890, protecting it from further logging. Despite its early history of logging, many magnificent sequoias remain, and visitors today can still see enormous stumps from this era, now often surrounded by younger sequoias, offering a poignant reminder of the grove's past and its resilience.
