We didn't see Ring-tailed lemurs until we reached Anja Reserve, in southern Madagascar. Well, we saw them in the Singapore zoo; they are one of the few lemurs that thrives in captivity, and the most common lemur found in zoos. Anja is located at the base of this massive rock formation. We spent a few hours there in the afternoon, after visiting Sidexam Tea’s factory, and before we reached our last destination, Isalo.
