The short answer
Gudiyam Caves Heritage Trail: what visitors should know first
Worth a morning if you like archaeology and an easy forest walk. The route is about 4.5 km each way on low, dry ground, booked as a guided trail with Trek Tamil Nadu. Start early; the heat is the real difficulty.
History and context
The story behind Gudiyam Caves Heritage Trail
Gudiyam is one of sixteen prehistoric rock shelters in the Allikulli hills near Poondi, first identified by the geologist Robert Bruce Foote. The Archaeological Survey of India excavated it in 1963 and 1964 and found Palaeolithic stone tools.

Why it matters
Why Gudiyam Caves Heritage Trail is worth your time
Gudiyam is one of the oldest human sites near Chennai. Stone tools found here and in the surrounding hills show that people were living and working in this landscape in the Palaeolithic, long before any of the city's temples or forts.
The walk also shows a side of Tiruvallur district most visitors miss: dry evergreen forest, monkeys and birdlife within a couple of hours of the city. Trek Tamil Nadu runs it as a guided trail so that numbers stay small and the site is protected.
Highlights
What not to miss
- 01

- 02
Dry evergreen forest
A low, scrubby forest type that is now rare along the Coromandel coast.
- 03
Poondi reservoir
The large reservoir nearby makes a calm stop for anyone not walking.
Plan your visit
How to experience it
Book a slot on the Trek Tamil Nadu website and drive to the Gudiyam reception point, about 60 km west of Chennai near the Poondi reservoir. Groups are small, up to about 15 people, and start at 7, 8 or 9 am with a forest department guide.
The trail runs about 4.5 km each way through tropical dry evergreen forest and scrub, reaching a maximum of only about 141 m (460 ft). The ground is level to gently rolling, but it is rough underfoot and has little shade in places. Allow about four hours for the round trip and time at the shelter.
The rock shelter itself is a large overhang in the Allikulli hills. There is little on site to explain it, so read a little before you go. Carry plenty of water, a hat and sunscreen, and keep to the guide's pace.
Plan with confidence
Small decisions that make the visit easier.
- Book a slot on the Trek Tamil Nadu website in advance
- Arrange your own car to the Gudiyam reception point
- Carry at least 2 litres of water per person
- Wear closed shoes, a hat and light full-sleeve clothing
- Carry personal medicines and photo ID
- Take all litter back with you
