The Javadhu (Jawadhu or Javadi) Hills are a broad block of the Eastern Ghats spread across Tiruvannamalai, Vellore and Tirupattur districts, separating the Tiruvannamalai plains from the Palar valley. The plateau rises to around 1,100–1,150 metres (3,600–3,800 feet), with forest, small farms and more than 200 hamlets, most of them home to Malayali tribal communities. Jamunamarathur is the main village and the base for visitors.
There are no big hotels, no crowds and very little that is staged for tourists. You come for cool air, a waterfall, a lake, quiet roads and one unusual extra – the chance to look through a telescope at one of India’s most important observatories.

Why go to the Javadhu Hills
Most hill stations within reach of Pondicherry are four to six hours away and well known. Javadhu is closer than most of them and far less visited. It suits travellers who like slow, unplanned days: a walk to a waterfall, an afternoon by the lake, an evening looking at stars. It also fits neatly onto a trip to Tiruvannamalai, only about 75 km away.
Things to see in the Javadhu Hills
Beema Falls
About 5 km from Jamunamarathur, Beema Falls is the best-known cascade on the hills. Local tourism listings say water flows for about eight months of the year, with the strongest flow after the monsoon rains. When the flow is moderate, visitors bathe in the pool at the base. Rocks get slippery and the forest department may restrict access after heavy rain, so check locally. See our Beema Falls guide for details.
Komutteri lake and the park
Komutteri (also called Kolappan) lake is the largest lake on the hills, with a small man-made island and a boat house. The district administration lists the boat house and park among the main sights. Boating depends on water levels and is not always running, so ask on arrival.
Vainu Bappu Observatory, Kavalur
At Kavalur, on the western slopes of the hills at about 725 metres, the Indian Institute of Astrophysics runs the Vainu Bappu Observatory. Its 2.3-metre telescope, completed in 1986, was the largest in Asia until 2014, and the site has a proud research record, including the first minor planet discovered from India in the 20th century, named after Ramanujan. At the time of writing the institute holds public night-sky sessions with a small telescope every Saturday from 7 pm to 10 pm, subject to clear skies, without advance booking. Check the Indian Institute of Astrophysics website before you go.
Villages, forests and old stones
The district notes Neolithic finds and old burial markers across the hills, and more than 100 megalithic burials were reported near Jamunamarathur in 2024. Melpattu village, high on the plateau, has a forest department herbal garden. The Malayali farmers grow millets such as samai, and the hills are known for jackfruit, tamarind and other fruit trees; sandalwood once grew widely here. The Kovilur Siva temple is another stop listed by the district. At the foot of the hills on the Vellore side, the Amirthi forest area has a small zoo.
Best time to visit
October to March is the most comfortable season, with cool nights on the plateau and clear skies for the observatory. The falls are best from about August to December, after the south-west and north-east monsoon rains. April and May are warm, though still milder than the plains. Avoid driving the ghat road after dark or in heavy rain.
How to reach the Javadhu Hills from Pondicherry
Drive west to Tindivanam or Gingee and on to Tiruvannamalai (about 108 km), then north-west via Polur, where the road starts to climb towards Jamunamarathur. The full distance is about 165 km and takes around four hours with a short break. The ghat road is narrow in places, so a driver used to hill roads helps.
We usually pair the hills with Tiruvannamalai: our Javadhu Hills and Tiruvannamalai weekend combines the Arunachaleswarar Temple with a night on the plateau. Experienced trekkers can add Parvathamalai, the steep sacred hill near the road between the two.
Sample weekend plan
- Saturday: Leave Pondicherry early, visit the Arunachaleswarar Temple in Tiruvannamalai, then drive up to Jamunamarathur; evening sky-watching at Kavalur if the sky is clear.
- Sunday: Beema Falls in the morning, Komutteri lake, a drive through the villages, then down the ghat road and back to Pondicherry by evening.
Javadhu Hills, Yelagiri or Yercaud?
All three are Eastern Ghats hills within a day’s drive of Pondicherry, but they feel very different. Yercaud (about 237 km) and Yelagiri (about 241 km) are established hill resorts with lakes, boating, viewpoints and plenty of hotels. Javadhu, at about 165 km, is closer but much less developed: fewer facilities, simpler rooms and more of a village feel. Choose Javadhu for quiet and stargazing, Yelagiri for an easy family weekend, and Yercaud if you want the most choice of stays and sights.
Where to stay and eat
Accommodation on the hills is limited to a few simple guesthouses, government rest houses and small private stays around Jamunamarathur. Many visitors stay in Tiruvannamalai and go up for the day. Food on the plateau is basic; carry snacks and water. We can help you find a suitable stay.
Practical tips
- Carry cash; ATMs and card payments are limited on the hills.
- Mobile coverage is patchy in parts of the plateau.
- Bring a warm layer for evenings, especially from November to February.
- Ask before photographing people in tribal villages.
- Do not leave plastic at the falls or the lake.
