Located atop a hill at Chengamanad, 30 km north of Kochi, this is a place shrouded in mythology. The word "Munikkal Guhalayam" literally means sages rock cave. It is believed that sage Jangaman had lived here around 2000 years ago, and the place was initially known as Jangaman, which later changed to Chengamanad. A famous Lord Murugan Temple is located on the spot where the sage is said to have meditated which was later consecrated by Chattambi Swamikal in 1898. Another story goes that Lord Murugan also called as Guhalayam had made this place his abode and hence the name Guhalayam.
