This is the one must-see attraction in Tuléar. Essentially a 400,000-sq-metre distillation of the entire spiny forest in one place, it's a fantastic collection of 900 plant species; take a guide (tip expected) to learn more about the weird and wonderful plants on show here. It was established by a Swiss botanist and conservationist in 1980; his ancient Citroen that once used to gather the plants is now being consumed by them. Madagascar National Parks (MNP) take note: clone this place. Night tours (Ar10,000) leave at 5.45pm.
