The tsingys are large limestone platforms heavily eroded by rain water in a process called 'karstification'. The process is common in limestone rocks across the planet – Cheddar Gorge is possibly the most famous example in the UK – but, while in the northern hemisphere the phenomenon gives rise to moderately eroded areas, in Madagascar, where everything is wild and extreme, it produces great structures like Gothic cities. In some of the crevices, the rain forest grows and much of the island's wildlife finds safe haven.
Some of the most spectacular tsingys can be seen in the Ankarana reserve, in the north of the island, near the RN-6, which connects Diego Suarez with Ambanja. Here there are more than 120 kilometres of caves, dozens of sinkholes and canyons whose depth will take your breath away. In the few areas of the Ankarana – whose name is Malagasy for 'the place where there are sharp rocks' - where the rock gives way to the rain forest, you may be lucky enough to see one of the many species of chameleons endemic to Madagascar, with their colourful changing skins, from the small short-horned chameleon to the fantastically coloured panther chameleon. The Ankarana Massif is considered sacred by the local Antakarana people, and several of their kings are buried in the caves here.
But the highlight of the Ankarana fauna is, without a doubt, the lemur, one of the best known and most studied of the Madagascar wildlife. These friendly mammals, half squirrel, half cat, are in fact proto-simians – which makes them distant cousins to the primates and even more distant relatives of man himself. How they got here and, more especially, why they have only survived in Madagascar is a mystery to science. It is known that when the island was separated from Africa they didn't yet exist, and that they arrived later, about 40 million years ago, allegedly on board floating tree trunks and floating islands of plant matter from the dark continent. There are nearly 100 different species on the island, all indigenous, ranging from the tiny Madame Berthe's Mouse Lemur, which weighs in at only 30 grammes (just over an ounce), to elusive nocturnal species such as the Aye-Aye, the species featured in Gerald Durrell's book, The Aye-Aye and I.
The best way to get to Ankarana to join one of the 4x4 expeditions organised by local agencies in Diego Suarez. There is no accommodation within the park, so the organisers provide all the necessary equipment for camping, or you can sleep in one of the lodges and cabins that are just outside the reserve. A night under the stars, with a great natural stone backdrop and the Malagasy sounds of nature as soundtrack, is an unforgettable experience.
