The first step of the mountain pathway starts at the place where Gajamukha Pillayar is in south and Aarumuga swamy in the north. This place is called the base of the mountain (malai adivaaram).
Passing through the stairway, we arrive at the Sengundhar Mandapam, and then at the Kaalathisuvaamigal mandapam, Thirumudiyar Mandapam, and finally arrive at the Thaili mandapam. To the west of Thaili mandapam, there is a Nandhi, 7 feet wide and 4feet high, facing the Gopuram tower. The part called as pasuvan kovil , place which is behind this is known as Naagamalai.
Here a magnificent statue of Adhisedan, with five heads, and 60 feet long, is present. The most special aspect of this is that we are able to see the Naagar structure of Aadhisedan, who bears the structure of Lord Shiva who wears Aadhisedan as an ornament. This Naagar structure, sculpted from a long rock, is the first place of Naagar Mountain. Even today, devotees worship this Nagar idol by anointing it with Vermilion and offering sweets and savouries, like sugar pongal and Venpongal. In olden times, the only way the people could reach the Naga Daivam was to travel up the stairs., At present, vehicular paths have been constructed to shuttle weaker devotees up to nagar pallam, from where they can offer worship to the shrine.
The devotees going through the steps can see the 60 feet long, five headed Aadhisedan and also worship Lord Muruga in the 60th step.
Once a year, during the grand celebrations of this festival, the devotees have a custom of carrying 1008 milk pots from the Bathrakaliamman shrine present at the foot of the hills, and walk up the divine stairway of the mountain.They worship the gods by fasting and performing a grand Abishekam for the 60 feet long, 5 headed Adhisedan idol situated at Naagar pallam. They also decorate the revered Nagadhevan idol with turmeric and Vermillion along with lime and worship him. This grand festival is celebrated on the Nagapanchami day every year, in the Tamil month of Aadi.
Crossing this, and passing a few Mandapams and halls, one can arrive at the sixtieth step [Arubatham Padi] which has special powers. This place which possesses 60 steps in a straight row has till today been considered a marvel in the sculpting sector. In all the 1206 steps present in the entire mountain, this step is extremely special. Unsolved cases in the past have been solved with the help of this step. One cannot lie when standing over this sacred step. People providing witness when standing over this sacred step are considered to be under a strict oath, almost like accepting a testimony in today’s high court.
Worshipping the God by climbing on the steps is a very wonderful and unique experience. While climbing up the steps, the sight of the nature’s beauty, temples of the Lord, and the play of monkeys are a treat not only for our eyes, but also make us joyful and happy. There are many halls built in the entire stretch for devotees to rest while climbing through the steps.
In 1599, Moroor Athapa Nallathambi Kaangeyen built the stairs leading up to the mountain

In 1974, Erode V.V.C.R Murugesamudhalaiyar brought electricity and power lamps to the mountain temple.
Holy Lord Arthanaareeswarar temple, Holy Lord Aathikesavaperumal temple and Holy Lord Sengottu Velavar temple – though all these three temples are situated individually here, the entire temple complex is known as Arthanaareeswarar temple.
Located in an area of 350 acres landscape, this holy mountain is 2000 feet above sea level. The temple is 650 feet high from the base of the mountain with 1206 steps to climb on to it. To worship the Lord present in the temple on the mountain top, buses are operated on behalf of the temple management. The devotees are also permitted to reach the temple with their own vehicles. Apart from this, devotees climb through the mountain steps to worship Ammaiyappar. Every month, on the full moon and new moon days, thousands of devotees climb through the mountain steps to worship the God. Crossing this and passing a few Mandapams and halls, one can arrive at the sixtieth step [Arubatham Padi] which has special powers.
Passing this step and crossing a few more Mandapams ,you can witness the temple of the majestic Iyangara Pillayar and a beautiful Gopuram constructed roughly 475 years ago.
