If you visit one place in western Madagascar, make it Parc National Bemaraha. A Unesco World Heritage Site, its highlights are the jagged, limestone pinnacles known as tsingy and the impressive infrastructure – via ferrata (mountain route equipped with fixed cables, stemples, ladders and bridges), rope bridges and walkways. Guides are compulsory and cost Ar75,000/135,000 per half/full day for up to four people.
Formed over centuries by the movement of wind and water, and often towering several hundred metres into the air, the serrated peaks would definitely look at home in a Dalí painting.
