Three 400-foot granite pillars with fenced valley viewpoints
Pillar Rocks is a set of three granite boulders standing shoulder to shoulder, each around 400 feet tall, managed by the Tamil Nadu Forest Department. A small garden and shaded viewing platforms sit near the base, with fenced sections overlooking the valley. The gap between the pillars is the site known as Devil's Kitchen / Guna Caves. The former trek to the top of the rocks is now closed to visitors.
