The Marunthuvazh Malai also known as the Maruthuva Malai,nearer to Vaikunda Pathi forms the part and the southernmost tip of the Western Ghats.
According to tradition, the Maruthuva Malai is a fragment of the Sanjeevi Mountain, a piece of which fell down here, and it was carried by Hanuman from Mahendragiri to Lanka for healing the fatal wounds of Lakshmana, the brother of Rama, the epic hero. It stretches for more than a km, reaching a height of 800 feet at the highest point. It is about 2 km from Swamithoppe and 11 km from Nagercoil.
This hill is also believed to be noted in Ayyavazhi mythology as Parvatha Ucchi Malai. Apart from the Mythology, this hill is historically related to the life of Vaikundar. So few theologians consider this hill as sacred and consider it one among the Ayyavazhi holy sites. Backing some quotes from Arul Nool and Akilam some even argue that Marunthuvazh Malai is one among the Pathis.
