We've been in The "Rova de Tsinjoarivo" for a day.According to me , the site is beautiful because there was a superposition between the ancient Merina's civilisations and the begining of the forest in the east of Madagascar. But I think that the infrastructure isn't enough to promote tourism : you can't arrive there without a 4*4 during the raing season. Thus If you want to go there you must use your feet along 10 km or something like that
