Madagascar holds 5% of the world's species, the Avenue of the Baobabs near Morondava silhouettes giants at sunset, and the lemur reserves at Andasibe and Ranomafana track indri and sifaka through rainforest.
End of rainy season with landscapes intensely green, lemur courtship and birthing in Andasibe, and the indri's eerie morning calls at peak.
Cool dry season the best window for southern travel, humpback whales off Île Sainte-Marie July-September, and Tsingy de Bemaraha tracks accessible.
Spring shoulder with Avenue of the Baobabs at peak photogenic light, and the Mahafaly tomb culture in the south accessible by 4WD.
Hot rainy season with cyclone risk on east coast January-March, but lemurs nursing young and Andasibe still accessible from Antananarivo.
