Muniyaras
Muniyaras Dolmens are burial chambers belonging to the Megalithic age made of huge rocky slabs. It is believed that this was the ideal place for the ancient sages for meditation and Yoga. There are many dolmens in and around Munnar especially Marayoor, Kovilkadavu and near the cliffs overlooking the Pambar River.
