The Boole Tree, located in the Sequoia National Forest, is one of the few remaining monarch trees in the Converse Basin area that was left after the historic logging in the late 1800s. The tree was named for the Converse Mill foreman, Frank Boole.

The Boole Tree is one of the largest in the world and is the largest tree within the National Forest system. The Boole Tree Trail has a bit of everything to offer.  Wildflowers, Giant Sequoias, forested backdrops and scenic panoramas of the Kings River Canyon are just some of the spectacular features you'll find along this trail.

To hike the entire 2.5 mile loop trail takes approximately 2 hours.  Ample parking, information and restroom facilities are located at the trailhead.
