Chinnar Wildlife Sanctuary is the odd one out among Kerala’s forests. While most of the state is wet and green, Chinnar sits in a rain shadow and wears a cover of dry thorn scrub, sun-bleached rock and sandalwood. It lies on the Kerala–Tamil Nadu border in Idukki district, near the sandalwood village of Marayoor, and it is the place to come for the grizzled giant squirrel, the Indian star tortoise and the Thoovanam waterfall.
Chinnar Wildlife Sanctuary, in Idukki district, Kerala, is a dry thorn-forest reserve of about 90.4 sq km on the Tamil Nadu border near Marayoor. Per Kerala Tourism, it was opened in 1984 and is one of only two Indian homes of the grizzled giant squirrel. It stays open through the monsoon, so plan guided treks between December and April.
Key takeaways
- Chinnar is a rain-shadow sanctuary of about 90.4 sq km in Idukki district, Kerala, with roughly 500 mm of annual rainfall — a dry thorn forest unlike Kerala’s wet jungles.
- The guided trek to Thoovanam Falls is 4 km, takes about three hours and costs ₹250 for Indians and ₹600 for foreigners, per Kerala Tourism (as of October 2026).
- Chinnar is one of only two places in India where you can see the endangered grizzled giant squirrel, and it holds the country’s only Indian star tortoise rehabilitation centre.
- Munnar is about 58 km away on State Highway 17; the same road runs on to Udumalpet in Tamil Nadu, and the nearest airport is Coimbatore, about 115 km.
- Unlike Kerala’s wet-forest parks, Chinnar stays accessible in the June–August monsoon because its heaviest showers come only around November.
- Marayoor’s natural sandalwood forest and the Iron-Age Muniyara dolmens sit about 20 km away, making an easy add-on to a Chinnar visit.
About Chinnar: quick facts
Chinnar Wildlife Sanctuary covers about 90.4 sq km in the Devikulam taluk of Idukki district, Kerala, straddling the border with Tamil Nadu. According to Kerala Tourism, the sanctuary was opened in 1984 and lies in the rain-shadow region of the southern Western Ghats, which is why it looks and feels so different from the rest of the state.
The Marayoor–Udumalpet highway (State Highway 17) roughly splits the reserve in two. The land climbs steeply within a few kilometres, from around 500 m near the Chinnar river to the high peak of Nandanmala at 2,372 m (7,782 ft). Two rivers, the Chinnar and the Pambar, run through it and feed the riverine strips where wildlife concentrates.
| Feature | Detail |
|---|---|
| Location | Idukki district, Kerala; on the Kerala–Tamil Nadu border |
| Area | About 90.4 sq km |
| Declared | 1984 |
| Terrain | Rain-shadow dry thorn scrub, dry deciduous forest, shola, grassland |
| Altitude | About 500 m to 2,372 m (Nandanmala peak) |
| Rivers | Chinnar and Pambar |
| Flagship species | Grizzled giant squirrel, Indian star tortoise |
| Managing office | Wildlife Warden, Munnar P.O., Idukki |
Eleven tribal settlements lie within the sanctuary, home mainly to the Muthuva and Hill Pulaya communities, per Kerala Tourism. They are partners in running the reserve, not a sight to be viewed; the eco-tourism programmes are managed jointly by the Forest Department and local Eco-Development Committees.
The dry-forest ecosystem and its wildlife
Chinnar is a dry thorn forest, and that single fact shapes everything you will see. It receives only about 500 mm of rain a year, spread over roughly 48 days, according to figures cited for the sanctuary — a fraction of what falls on Kerala’s wet forests. The result is thorny scrub with xerophytic (drought-adapted) plants, dry deciduous woodland, and pockets of shola and grassland higher up.
The star attraction is the grizzled giant squirrel (Ratufa macroura), a large, shaggy, salt-and-pepper squirrel named for its grizzled grey coat. Kerala Tourism describes Chinnar as its second home in India, and the riverine forest along the Chinnar and Pambar supports a healthy population. You can often spot one in the trees near the Chinnar check post without a long walk.
Chinnar is also the dry-country specialist’s sanctuary. The scrub supports the Indian star tortoise (Geochelone elegans), and the sanctuary runs what The Hindu reported in 2017 is the only Indian star tortoise rehabilitation centre in the country. The reserve records a notably rich reptile list — 52 reptile species, including 29 snakes, in Kerala Forest Department figures from 2012.
Larger animals share the forest too. Elephants move through the sanctuary, which is why walking or driving the highway after dark is risky; spotted deer, common langur and gaur are seen on the drier slopes. Birdlife is strong, with 225 recorded species. There are no jeep safaris here, so wildlife-watching is done on foot with a guide or from the roadside in daylight.
| Species | Why it matters | Where / when |
|---|---|---|
| Grizzled giant squirrel | Endangered; Chinnar is one of two Indian homes | Riverine trees; near Chinnar check post, early morning |
| Indian star tortoise | Dry-scrub reptile; sanctuary runs India’s only rehab centre | Scrub forest; interpretation centre |
| Asian elephant | Resident herds; avoid the road after dark | Across the sanctuary; daylight only |
| Spotted deer and gaur | Common grazers of the dry slopes | Open scrub and grassland |
| Birds (225 species) | Dry-forest and riverine specialists | Pambar/Chinnar riverbanks, treks |
Best time to visit Chinnar Wildlife Sanctuary
The best time to visit Chinnar is the cool, dry window from December to April, when trails are firm and sightings are good. The real advantage over the rest of Kerala is the monsoon: because Chinnar sits in a rain shadow and gets its heaviest showers only around November, it stays open and walkable in June–August, when wet-forest parks like Periyar and Eravikulam are at their soggiest.
A dry-forest bonus noted by local coverage is the near-absence of leeches, which plague Kerala’s wet trails. Carry sun protection instead: the scrub offers little shade and midday heat on the lower trails can be sharp.
| Season | Months | What to expect |
|---|---|---|
| Cool and dry (best) | December–February | Pleasant days, firm trails, good sightings |
| Warm and dry | March–April | Hotter afternoons; animals near water; still good for treks |
| Southwest monsoon | June–August | Open and walkable; green flush; a dry-forest advantage over wet parks |
| Local rains | October–November | Chinnar’s own showers arrive; check trek availability |
How to reach Chinnar
Chinnar is reached by road, most often from Munnar, which lies about 58 km away on State Highway 17, the Munnar–Udumalpet road; the same highway continues north to Udumalpet in Tamil Nadu. There is no railway station or airport at the sanctuary, so you drive in, and the check post sits right on the highway.
By air, the nearest airport is Coimbatore (about 115 km), with Cochin International further off. By rail, Pollachi is the nearest useful railhead at about 60 km, while Aluva (near Kochi) is about 200 km. The Munnar road is a scenic ghat drive through tea country and the Marayoor sandalwood belt, so allow more time than the distance suggests.
| From | Distance | Notes |
|---|---|---|
| Munnar | About 58 km | Scenic SH-17 ghat road, around 2 hours |
| Coimbatore (nearest airport) | About 115 km | Via Udumalpet; nearest flights |
| Pollachi (nearest railhead) | About 60 km | Tamil Nadu side |
| Kochi / Aluva | About 200–208 km | Cochin International Airport and Aluva station |
Top things to see and do
The headline experiences at Chinnar are the Thoovanam waterfall trek, wildlife-watching for the grizzled giant squirrel, and the cultural pairing of Marayoor’s sandalwood forest and the Muniyara dolmens just outside the reserve. Everything inside the sanctuary is done with a forest guide; there are no self-drive safaris.
Thoovanam Falls trek. The Thoovanam waterfall sits inside the sanctuary and is reached on a 4 km guided trek of about three hours from the Alampetty check post, per Kerala Tourism. The Chinnar river keeps you company for part of the walk, and the falls come into view toward the end. It is rated a moderate trek; timings run roughly 8 am–2 pm.
River trekking and dolmen walk. Guided river-trekking along the Chinnar and a separate walk to prehistoric dolmen sites near the hamlets are both bookable at the check post. These are gentle introductions to the dry forest and good for squirrel and bird sightings.
Marayoor sandalwood forest. Marayoor, about 20 km from Chinnar, is the only place in Kerala with natural sandalwood forest. The stands are protected, so you view them from the road and designated points rather than walking in freely.
Muniyara dolmens. Around Marayoor stand the Muniyara dolmens — Iron-Age burial chambers (locally “muniyara”) built of stone slabs set on edge under a capstone. Marayoor has one of Kerala’s largest concentrations of these megaliths, a striking stop for anyone interested in the region’s prehistory.
| Spot / experience | What it is | Time needed |
|---|---|---|
| Thoovanam Falls trek | 4 km guided trek to a river waterfall | About 3 hours |
| Chinnar check post squirrel spotting | Grizzled giant squirrel in roadside trees | 30–60 minutes |
| River trek / dolmen walk | Guided riverine and megalith walks | 2–3 hours |
| Marayoor sandalwood forest | Kerala’s only natural sandalwood stands | 1–2 hours |
| Muniyara dolmens | Iron-Age megalithic burial sites | 1 hour |
Eco-tourism programmes and fees
Eco-tourism at Chinnar is run jointly by the Forest Department and tribal Eco-Development Committees, and you sign up at the check post or through the Wildlife Warden’s office in Munnar. The headline guided trek to Thoovanam Falls is priced, per Kerala Tourism, at ₹250 for Indian visitors and ₹600 for foreign visitors; a separate Marayoor-area wildlife drive is offered at ₹3,000 for a three-hour slot or ₹6,000 for five hours.
Forest-managed stays inside or near the sanctuary include a tree house at Chinnar and machans (raised watch platforms) at points such as Koottar, Karakkad and Champakkad, plus trekking-and-camping at Vasyappara. Rates for these are not published online and change often, so treat any figure you see as an indicative planning estimate and reconfirm with the Wildlife Warden’s office before you travel.
| Programme | Duration | Fee |
|---|---|---|
| Thoovanam Falls trek | About 3 hours (4 km) | ₹250 Indian / ₹600 foreigner |
| Marayoor-area wildlife drive | 3 hours | ₹3,000 (per the published slot) |
| Marayoor-area wildlife drive | 5 hours | ₹6,000 (per the published slot) |
| Tree house / machan stay | Overnight | Indicative — reconfirm with Wildlife Warden |
A suggested two-day itinerary
Two days is enough to combine the sanctuary’s wildlife with Marayoor’s culture, using Marayoor or Munnar as your base.
- Day 1: Drive from Munnar, stopping for tea-country and sandalwood-belt views. Reach the Chinnar check post, sign up for the guided Thoovanam Falls trek, and watch for the grizzled giant squirrel near the entrance in the afternoon light.
- Day 2: Take an early river trek or dolmen walk, then explore the Marayoor sandalwood forest and the Muniyara dolmens before driving back. Be off the forest road well before dark because of elephants.
If you have a third day, pair Chinnar with Munnar’s tea estates and Eravikulam National Park — see our Munnar travel guide for how to slot them together.
Where to stay
There is no large hotel strip at Chinnar itself, so most visitors stay at Marayoor, the nearest town, or base themselves in Munnar and make a day trip. Marayoor has homestays and small eco-lodges close to the sandalwood forest; Munnar has the full range from budget lodges to resorts.
- Budget (about ₹1,000–₹2,500 a night): Marayoor homestays and small guesthouses; simple Munnar lodges. Indicative, as of October 2026.
- Mid-range (about ₹2,500–₹6,000 a night): Eco-lodges and tea-view hotels around Marayoor and Munnar.
- Forest stays: The Forest Department’s tree house and machans inside/near the sanctuary; book through the Wildlife Warden’s office well ahead, as capacity is tiny.
Book ahead for weekends and the December–April peak. Price bands are indicative planning estimates — reconfirm current tariffs when you book.
Budget breakdown
A two-day Chinnar trip from Munnar costs roughly ₹4,500–₹8,000 per person for a mid-range plan, excluding how you reach Munnar. The biggest variables are your room and whether you hire a private car. The figures below are indicative planning estimates as of October 2026; confirm current rates before you travel.
| Item | Estimate | Notes |
|---|---|---|
| Stay (1 night) | ₹1,500–₹3,000 | Marayoor homestay or Munnar hotel, shared twin |
| Guided Thoovanam trek | ₹250 | Indian visitor fee per Kerala Tourism |
| Food (2 days) | ₹600–₹1,200 | Local meals; Kerala and Tamil cuisine |
| Transport (shared car) | ₹1,500–₹3,000 | Munnar–Chinnar day hire, split |
| Buffer / entry extras | ₹500 | Camera, guide tips, local travel |
Permits and rules
No special inner-line or state permit is needed to visit Chinnar — it is an ordinary Kerala wildlife sanctuary open to Indian and foreign visitors, and you simply pay the programme fee at the check post. The one formal requirement is that treks inside the forest must be done with a Forest Department guide; independent walking off the highway is not allowed.
- Go with a guide for all forest treks; sign up at the Alampetty or Chinnar check post.
- Carry a valid photo ID; foreign visitors may need passport details for records.
- Single-use plastic is discouraged in the sanctuary; carry your waste out.
- Do not feed or crowd wildlife, and keep quiet near the river where squirrels feed.
- Drone use over a protected forest needs prior Forest Department permission — do not assume it is allowed.
Practical tips
Treat Chinnar as a dry, remote forest: carry what you need and plan around daylight. Mobile network is patchy inside the sanctuary, so download maps and confirm bookings before you arrive. Cash is useful for fees and small shops; UPI works in Marayoor and Munnar but not reliably at the forest gate.
- Elephants: Do not walk or drive the forest road after dark; plan to finish activities in daylight.
- Heat and sun: The scrub gives little shade — carry water, a hat and sunscreen.
- Health: The nearest hospitals are in Marayoor and Munnar; carry a basic kit.
- Solo women travellers: Day visits with a registered guide are straightforward; base in Marayoor or Munnar and travel the ghat road in daylight.
- Packing: Sturdy shoes for the Thoovanam trail, light cottons for the heat, and a warm layer if you continue to high-altitude Munnar.
Nearby places
Chinnar pairs naturally with the hill stations and forests of the high Western Ghats, all within a short drive. Marayoor and Munnar are the obvious combinations, with Eravikulam National Park and the Anamudi peak completing a classic high-range loop.

Frequently asked questions
Where is Chinnar Wildlife Sanctuary located?
Chinnar Wildlife Sanctuary is in Idukki district, Kerala, on the Kerala–Tamil Nadu border near the town of Marayoor. It sits on State Highway 17, the Munnar–Udumalpet road, about 58 km from Munnar. The check post is on the highway, and the sanctuary covers about 90.4 sq km of dry forest.
What is the best time to visit Chinnar?
The best time to visit Chinnar is December to April, when the days are cool and trails are firm. Unusually for Kerala, the sanctuary also stays open and walkable during the June–August monsoon, because it lies in a rain shadow and its heaviest showers come only around November. Avoid midday heat in March and April.
How much does the Thoovanam Falls trek cost?
The guided Thoovanam Falls trek costs ₹250 for Indian visitors and ₹600 for foreign visitors, per Kerala Tourism as of October 2026. It is a 4 km, roughly three-hour moderate trek from the Alampetty check post, with timings around 8 am to 2 pm. Fees change, so reconfirm at the check post or the Wildlife Warden’s office.
What animals can I see at Chinnar?
Chinnar’s signature animal is the grizzled giant squirrel, which lives here in one of only two Indian populations. You may also see the Indian star tortoise, elephants, spotted deer, gaur and common langur, plus 225 recorded bird species. The sanctuary runs India’s only Indian star tortoise rehabilitation centre, per The Hindu (2017).
Do I need a permit to visit Chinnar?
No special permit is needed to visit Chinnar, which is a regular Kerala wildlife sanctuary open to all visitors. You pay the programme fee at the check post. The one rule is that forest treks must be done with a Forest Department guide; independent walking off the highway is not allowed, and drone flying needs prior permission.
How is Chinnar different from other Kerala forests?
Chinnar is a dry thorn forest in a rain shadow, receiving only about 500 mm of rain a year, while most Kerala forests are wet and green. This gives it drought-adapted scrub, the Indian star tortoise and the grizzled giant squirrel, far fewer leeches, and the rare quality of staying open through the southwest monsoon.
Last updated and sources
Chinnar suits travellers who want dry-forest wildlife, a moderate waterfall trek and a dose of prehistory, best paired with Munnar between December and April. Go with a Forest Department guide, respect the elephants on the road, and reconfirm fees before you travel.
