Wander through a serene eucalyptus grove in the Presidio to discover a unique piece of art seamlessly woven into the landscape. You'll find a winding, 1,200-foot line of recycled eucalyptus trunks snaking through the forest floor, a whimsical creation by artist Andy Goldsworthy. It's a favorite spot for a peaceful walk, and many can't resist the playful challenge of balancing on the sculpture itself. The trail to Wood Line is easily accessible from the nearby Presidio Blvd, making for a quick and magical escape into nature and art.
