The Complete Guide to the Athri Hill Trek

The Athri Hill Trek is a short yet beautiful trek located in the Pothigai mountain range of the Western Ghats near the village of Alwarkurichi. A hidden gem that is yet to be discovered by outdoor lovers, this trek is 25 kilometres from the Tenkasi district in Tamilnadu. 

The Athri Hill trail lies inside the north-eastern section of the Kalakkad Mundanthurai Tiger Reserve Forest.

The beautiful Kadana Nathi Dam (Nathi means River in Tamil), dense forest trails, an unusually shaped limestone cave and spectacular views of the Western Ghats are just some of the highlights of the Athri hill trek. The best part? The surprises don’t stop there. Read on for more information about the best sections and the standout parts of this trek.

History of the Trek

According to Hindu Purana, it is believed that the great sage Athri travelled through the Pothigai mountain region of the Western Ghats with his wife Anusya Devi and his disciples around 2,500 years ago. He considered the area to be a holy spot to perform penance for Lord Shiva. Moved by the unflinching devotion of his disciple, Lord Shiva appeared before the sage. As a result, the mountain range came to be known as the Athri Hills.

Today, the hills still hold religious significance for devotees who make the hard climb to pay their respects to the Shiva temple that was built in the middle of the forest a long time ago.

Athri Hill is blanketed in evergreen forests from its base to its highest peaks. This is in contrast to other mountains in the Southern regions, where thorny scrub forests are prevalent at lower elevations. 

The Athri hill trek is a moderate level trek that can be completed in two hours by fit trekkers and three hours by beginners.

Highlights of the Highlights of the Athri Hill Trek

1. The breathtaking view of the Kadana Nathi Dam

The Athri Hill Trek offers a beautiful view of Kadana Nathi Dam with the Western Ghats opening up behind it. 

Walking across the Kadana Nathi Dam with a large number of birds flying overhead and views of the Western Ghats giving you company is a great way to start the trek. 

During monsoon and post-monsoon season, the dam fills up with water and you will have to walk an extra two kilometres around the dam. However, this extra effort is rewarded with views of the lush green surroundings and the calm waters of the dam.

2. Dense yet less trodden forest trail

Rich foliage and the towering trees make this trek an exciting one. Picture by Ajay Vignesh.

The Athri Hill Trek is a combination of an easy hike by the river, a deep forest trek and a steep, vertical climb. 

Walking through the deep forest is an adventure in itself and the experience of walking amongst tall trees makes this trek a truly special one.

 Unlike many other Southern hill treks, Athri Hill provides a clear glimpse of the fascinating mycorrhizal network between trees. As you trek along, you will notice many roots cross the path and link to the trees on the opposite side.

3. Unique limestone caves

One of the best highlights of this trek is the old limestone rock caves that you will come across during your hike. It is widely believed that Sage Korakkar, one of the earliest proponents of Siddha medicine, frequented at least one of these caves for meditation and medicinal experimentation.

The green limestone cave has a fairly narrow entrance. If you do manage to squeeze in, you will find just enough sitting space for a single person.

Be mindful when touching and exploring the cave as many tiny bugs can be found inside the cave’s fissures.

4. Spectacular view of the Western Ghats

The Athri Hill Trek greets you with refreshing views of the Western Ghats right from the get-go. While many treks provide spectacular summit views, this trek allows you to take in the expansiveness and beauty of the Western Ghats at the start itself.

Once you reach the end of the trek, you get to experience a bird’s eye view of the Alwarkurichi village dotting the plains and the picturesque Kadana Nathi Dam from the summit.

➤ Trail Information

Athri Hill can be reached in two ways. 

During the dry season, when the Kadana Nathi Dam dries up and the catchment area only has stagnant water in some sections, you can access Athri Hill by walking across the dam. If you take this path, the trek will be 2 kilometres shorter.

Do note that the GPX file traces the path of the trek during the dry season which goes across the dam. If you are trekking during the monsoon season, your route will be different from that shown in the GPX file.

During the monsoon season, when the dam fills up, you’ll have to go around the Kadana Nathi Dam and through the dense forest to cross the Stone River to rejoin with the first route.

The Athri Hill Trek can be divided into four sections.

If you arrive by your own vehicle, you can skip the first stretch till you reach the Kadana Nathi Dam.

1. Auto/Bus travel from Alwarkurichi bus stop to Kadana Nathi Dam
2. Walk from Kadana Nathi Dam to Deep forest trail point
3. Trek from forest trail point to limestone cave
4. A short steep hike from Limestone cave to Athri Hill summit

When you get off the bus at the Alwarkurichi bus stop, you will see a four-way junction in front of you. You will find a small sweet shop to the left. You can inquire about bus availability to the Kadana Nathi Dam over here.

There are usually only two buses that run to Kadana Nathi Dam. The first bus leaves about 7:15 a.m., and the second bus usually leaves around 11:30 a.m. The second bus operates only when there are enough passengers, so it is best to take the 7.15 am bus to Kadana Nathi Dam. 

Protip: If you reach Alwarkurichi before 7:00 a.m., it is recommended that you take the first bus to Kadana Nathi Dam; otherwise, you can hire an auto from the Auto stand on the right side (opposite to the sweet shop). The auto fare from the Alwarkurichi bus stop to Kadana Nathi Dam costs around Rs. 250.

Om Sakthi Auto service is cheap and one of the reliable sources.

The distance from Alwarkurichi to Kadana Nathi Dam is around ten kilometres and it takes 25-30 minutes to cover the distance. The road leading to the dam is a scenic one and is surrounded by lush agricultural land and the Western Ghats.

After receiving your entry passes, the forest department officials will instruct you on the do’s and don’ts of the trek. It is recommended that you go on the trek as a group, especially if you are a first-time trekker in the region, as there is a threat of wild animals and the possibility of getting lost in the dense forest.

A 10-minute hike along the mud route will lead you to a little flowing stream. The stream serves as a marker that the mud route has come to an end and that the narrow rugged path surrounded by high, dense vegetation is about to begin.
