Visit the famous Arunachalesvara Temple, a sacred Hindu temple dedicated to Lord Shiva. The temple is spread over 25 acres and is believed to be one of the largest temples in India. It has four large gateway towers and a large inner courtyard with many smaller shrines.
Next, visit Sri Ramanashramam, the ashram where the famous Hindu sage, Sri Ramana Maharshi, lived and taught for many years. The ashram has a peaceful atmosphere and offers a great view of the sacred Arunachala hill.
Start your second day with a visit to Gingee Fort, a 13th-century fort complex known for its architectural beauty. The fort has three hilltop citadels and is surrounded by steep and rugged hills. It offers great views of the surroundings.
Finally, head to the Sathanur Dam, a popular picnic spot with a beautiful lake surrounded by hills. The dam is 59 feet in height and 1,550 feet in length and is a great place to relax and enjoy the natural beauty of the area.
If you have more time, you can head to other nearby tourist attractions such as the Virupaksha Cave, Vedapureeswarar Temple, and the Skandashramam. If you have less time, you can skip the Sathanur Dam and spend more time exploring the other locations. It is recommended to visit the temples in the morning to avoid crowds. Also, wear comfortable footwear as there is a fair amount of walking involved in most locations.
