Aryankavu is renowned for its Ayyappan temple, which is one of the five most significant temples dedicated to Lord Ayyappa in Kerala. The temple, also known as Aryankavu Shastha Temple, portrays Lord Ayyappa as a young boy. The name Aryankavu originates from the fact that Lord Ayyappa is referred to as Tiru Aryan. Nestled amidst forests, the temple is situated on the Trivandrum – Tenkasi National Highway. Similar to Sabarimala, women between the ages of 10 and 50 are not allowed inside the Aryankavu Ayyappa Temple. The rituals and pujas followed at Aryankavu Sastha Temple adhere to Tamil traditions.
