The short answer
Javadi Hills and Amirthi Forest Trails: what visitors should know first
The easiest way into the Javadi Hills from Vellore is a guided Trek Tamil Nadu walk at Amirthi: a 2 km easy loop or a 4 km waterfall trail. The higher hills are best seen by car, and the Kavalur observatory opens to the public on Saturdays.
History and context
The story behind Javadi Hills and Amirthi Forest Trails
The Javadi (Javadhu) Hills are an arm of the Eastern Ghats spread across Vellore, Tirupattur and Tiruvannamalai districts, home mainly to Malayali tribal communities. The Vainu Bappu Observatory at Kavalur in the hills began work in 1967.

Why it matters
Why Javadi Hills and Amirthi Forest Trails is worth your time
The Javadi Hills are one of the larger hill ranges of northern Tamil Nadu, yet they see few visitors. Sandalwood, fruit orchards and millet fields shape the landscape, and in 2024 more than 100 megalithic burials were found in reserve forest near Jamunamarathur.
The Amirthi trails are a gentle introduction to this forest, close enough to Vellore for a half-day trip. Booking through Trek Tamil Nadu keeps group sizes small and helps fund forest protection and local guides.

How to experience it
Trek Tamil Nadu runs two guided walks from the Amirthi Zoological Park, about 25 km from Vellore. The Amirthi Zoo Trail is a 2 km easy circuit of about an hour to the Perumal Koil temple in the forest, reaching about 310 m (1,020 ft). The Amirthi Falls Trail is a 4 km moderate circuit of about three hours to the Amirthi waterfall and on towards Neplampattu. Both start at 8 am, with groups of up to 15.
The forest here is dry deciduous with riverine strips along the streams. Gaur, spotted deer, pythons, pangolins and many birds and butterflies live in the area, although sightings are never guaranteed. After the rains the waterfall is lively; in dry months it may be a trickle.
For a longer day, drive into the hills to Jamunamarathur, the main town on top, or to the Vainu Bappu Observatory at Kavalur. The observatory is open to visitors on Saturday afternoons and evenings, with stargazing if the sky is clear. The Beemanmadavu waterfall lies deeper in the hills on the Polur side and needs local directions.
Plan with confidence
Small decisions that make the visit easier.
- Book the trail on Trek Tamil Nadu before you travel
- Hire a car from Vellore; public transport to the trailhead is limited
- Wear closed shoes; rocks near the falls can be slippery
- Carry water, snacks and insect repellent
- Visit Kavalur on a Saturday only, and check the timings first
Know before you go

- Area
- Amirthi Reserve Forest, about 25 km from Vellore, and the Javadi Hills beyond
- Time needed
- 1 to 3 hours on the trail; a full day if you also drive into the hills
- Best time
- After the monsoon, roughly October to February, when the forest is green and the heat is lower
- Walking level
- Moderate
- Senior comfort
- The 2 km Amirthi Zoo Trail is graded easy and suits most older travellers who walk regularly. The 4 km waterfall trail is longer and rockier and is better left to fitter family members. Parents who prefer not to walk can enjoy the drive into the hills or a Saturday visit to the Kavalur observatory.
- Tickets and access
- Amirthi trails are booked through Trek Tamil Nadu (Tamil Nadu Forest Department); the fee includes the permit, guide and insurance. The Vainu Bappu Observatory charges a small entry fee at the gate on Saturdays. Confirm current fees locally.
