Madagascar's extraordinary diversity of chameleons is one of the island's great natural spectacles, and Andasibe is a reliable place to encounter multiple species in a single visit. Both day and night walks yield sightings, with different species active at different hours.
During daylight, guides search through dense vegetation for cryptically coloured animals — Calumma crypticum (the cryptic chameleon) and the larger Calumma parsoni (Parson's chameleon) being the most prized daytime finds. At night, sleeping chameleons turn pale and become visible with torchlight from several metres away. Small Brookesia leaf chameleons, resembling dead leaves on the forest floor, are found only with careful searching — some species here are smaller than a fingernail. A single guided walk in the right conditions can yield six or eight chameleon species.
