Welcome to LSU Hilltop Arboretum! These fourteen extraordinarily beautiful acres in Baton Rouge showcase an extensive collection of Louisiana native trees and shrubs. The property known as Hilltop is located on Highland Road south of LSU.

You are invited to cross the old footbridge overlooking a twenty foot deep ravine and wander into the tranquil “cathedral”, where tree canopies form a green protective room. Discover the bamboo grove where you can sit and listen to the wind in the trees. In the meadow, tall grasses and colorful autumn wildflowers shimmer in the bright Louisiana sunlight. The visitor to LSU Hilltop Arboretum will find not only a place of learning, but a quiet place, far removed from the pressures of life; a place of solace and contemplation.
