Thommankuthu Waterfalls, in the Thodupuzha taluk of Idukki district, Kerala, is a seven-step forest cascade and one of the state’s long-running forest eco-tourism sites. It is a day-trip spot from Thodupuzha town, run by the Kerala Forest Department with a small entry fee, and it draws walkers, picnic groups and families who want a short forest trail with pools rather than a single sheer drop.
Thommankuthu Waterfalls is a seven-step cascade in a reserve forest about 18 km from Thodupuzha town in Idukki district, Kerala. It is run as a Kerala Forest Department eco-tourism centre, opens daily from 8 am to 6 pm, charges a nominal entry fee, and is reached most easily by road from Thodupuzha.

About Thommankuthu Waterfalls and quick facts
Thommankuthu Waterfalls is a stepped forest cascade, not a single plunge: Kerala Tourism describes it as a “seven-step thundering cascade,” and the District Tourism Promotion Council (DTPC) Idukki says the water descends in seven distinct steps, with a pool at the foot of each. It lies in a reserve forest in the Thodupuzha taluk of Idukki district.
The name is explained by local folklore. According to local belief, the falls are named after a man called Thomman who drowned while trying to cross the stream; “kuthu” in Malayalam refers to a waterfall. Treat that as legend rather than documented history.
Two linked falls are usually named here. DTPC Idukki lists Thommankuthu and a second cascade, Ezhunilakuthu, in the same forest. The stream itself is named differently across sources: DTPC Idukki calls it the Kannadiyaar, while Wikipedia’s infobox names it the Kaliyar — and the Forest Department range is itself called Kaliyar, so reconfirm the name locally.
A word on disambiguation: Thommankuthu is often marketed under “Munnar” in tourism listings, but it is not in Munnar. It sits near Thodupuzha, on the lower, western side of Idukki district. Do not confuse it with the other “kuthu” falls on the same trail — Ezhunilakuthu, Nakkayam and Chekuthankuthu.

Official sources do not publish a verified height for the cascade. Some travel sites quote large figures, but none is backed by a primary source, so this guide leaves the height out rather than repeat an unverified number.
Best time to visit Thommankuthu Waterfalls
The best time to see Thommankuthu in full flow is the monsoon and the weeks just after it, roughly June to January. Kerala Tourism notes the streams gush with full force in the monsoon and the waterfall’s roar carries a long way. For safer walking and bathing, the drier weeks after the rains — September to January — are the more comfortable window.
The trade-off is real. At peak monsoon the rocks are slippery and the pools rise fast, which is exactly when the site is most dangerous (see Practical tips below). In the hot, dry months of March to May the flow thins and some pools shrink, but the trail is easiest underfoot.
| Season | Months | What to expect |
|---|---|---|
| Southwest monsoon | Jun–Sep | Fullest flow and loudest falls; slippery rocks, rising pools, highest risk — do not bathe when water is high |
| Post-monsoon | Oct–Jan | Strong but steadier flow, green forest, cooler air; generally the most comfortable time to walk and picnic |
| Summer | Feb–May | Thinner flow, smaller pools, warm days; easiest trail footing but less dramatic water |
How to reach Thommankuthu
Thommankuthu is reached by road from Thodupuzha, the nearest town. There is no railway station or airport close to the falls, so most visitors drive or take a bus to Thodupuzha and continue by local bus, taxi or auto to the Forest Department gate. Kerala Tourism places the falls about 18 km from Thodupuzha; DTPC Idukki gives about 21 km by road from the bus stand.
By air: the nearest airport is Cochin (Kochi) International Airport, about 63 km away per DTPC Idukki. From the airport you can hire a taxi or reach Thodupuzha by bus, then continue to the falls. Our Kochi travel guide covers arrival logistics and onward transport from the Kochi side.
By rail: the nearest railhead is Aluva, about 65 km away per DTPC Idukki; Ernakulam is the other practical option. From either, continue by road to Thodupuzha.
By road: Thodupuzha is well linked by Kerala State Road Transport Corporation (KSRTC) and private buses from Kochi, Ernakulam and Munnar. From Thodupuzha, local buses, autos and taxis run to the falls area. If you are building a wider Kerala route, our Kerala travel guide helps you slot Idukki into a larger itinerary.
| From | Approx. distance | Mode |
|---|---|---|
| Thodupuzha town | About 18–21 km | Road (bus/taxi/auto) |
| Aluva Railway Station | About 65 km | Rail, then road |
| Cochin International Airport | About 63 km | Air, then road |
The falls, pools and things to do
The main draw is walking up the stepped cascade and resting by the pools. DTPC Idukki describes smaller falls descending in seven distinct steps, each with its own pool, and mentions a forest trail that passes caves, rest huts and settlements deeper in. Kerala Tourism frames a visit as a dip in the pool below the falls followed by a trail that traces the water upstream.
DTPC Idukki also lists boating, fishing and rock climbing among activities associated with the site. These depend on season, water level and Forest Department clearance, so confirm what is actually running on the day before you plan around them. The forest is dense; DTPC notes the upper trail needs careful navigation, which is why guided treks exist.
| Activity | Notes | Time needed |
|---|---|---|
| Lower cascade and pools | Short walk from the gate to the first falls and pools; the main picnic area | 1–2 hours |
| Forest trail upstream | Climb past successive steps; rougher and slippery when wet — footwear with grip helps | 2–3 hours |
| Guided Nakkayam–Thommankuthu trek | 5 km Forest Department trek past more falls and caves; pre-booking required | Most of a day |
| Boating / fishing / rock climbing | Listed by DTPC Idukki; availability varies by season and clearance — confirm first | Varies |
The Nakkayam–Thommankuthu forest trek
The Forest Department runs an organised one-day trek here, and it is the proper way to go beyond the lower falls. Kerala Tourism lists the Nakkayam–Thommankuthu trek as a 5 km trail through rocky, dense forest, open 8 am to 4.30 pm, with pre-booking required and a maximum of nine people per trek.
The listed fee is ₹1,500 for up to five persons (the minimum rate) and ₹250 for each additional person, as of October 2026 — reconfirm when booking. The route passes the Nakkayam and Chekuthankuthu waterfalls and the Nakkayam, Chekuthan Kuthu and Plapothu caves. Packages depend on weather, so availability is not guaranteed day to day.
Bookings and enquiries go through the Forest Department: Kerala Tourism lists the Divisional Forest Office, Kothamangalam (+91 485-2822317) and an enquiry/booking number (+91 85476 01306). DTPC Idukki additionally lists the Range Officer, Kaliyar (+91 85476 01302) and DTPC Idukki (+91 4862 232248). Call ahead; do not assume walk-in trekking is possible.
A suggested day plan
Thommankuthu suits a half- to full-day outing from Thodupuzha or Kochi. A simple, safe plan:
- Morning: leave Thodupuzha early, reach the gate soon after opening at 8 am while it is quiet and cool, and walk the lower cascade and pools.
- Midday: picnic near the lower falls, then take the forest trail up as far as conditions allow, or join a pre-booked guided trek if you arranged one.
- Afternoon: head back well before the 6 pm closing; light fades early under the forest canopy.
If you want the organised trek, start at opening time — Kerala Tourism notes arriving early leaves more time in the forest, and the trek itself closes entry by 4.30 pm.
Where to stay near Thommankuthu
There is no accommodation at the falls themselves. DTPC Idukki points visitors to Kerala Tourism’s accredited “where to stay” listings for Idukki, and in practice Thodupuzha town is the nearest base, with Kochi and Munnar as larger alternatives for a wider trip.
The figures below are indicative planning estimates for the Thodupuzha–Idukki area (October 2026) and are not live-verified tariffs — reconfirm current rates and book ahead in peak monsoon and holidays.
- Budget (indicative, reconfirm): simple lodges and guesthouses in Thodupuzha, roughly ₹800–₹1,800 a night.
- Mid-range (indicative, reconfirm): hotels and homestays around Thodupuzha and Idukki, roughly ₹2,000–₹4,500 a night.
- Higher-end (indicative, reconfirm): resorts in the wider Idukki/Munnar belt, from about ₹5,000 upward.
For government and accredited options, check Kerala Tourism’s classified-accommodation directory rather than relying on a single booking app.
Food to try around Thodupuzha
There are no reliable eateries inside the forest site, so carry water and food, and plan meals in Thodupuzha. The local cooking is standard central-Kerala fare, worth trying in town:
- Puttu with kadala curry (steamed rice-and-coconut cylinders with black-chickpea curry) — a common breakfast.
- Appam with stew (lacy fermented rice pancakes with a mild coconut-milk vegetable or chicken stew).
- Kerala sadya (a vegetarian rice meal with many small sides, served on a banana leaf), easiest to find at lunch.
- Beef or fish curry with rice or Kerala parotta (layered flatbread) at local restaurants.
Meal costs are not fixed and vary by place; budget a modest amount per meal and confirm locally.
Budget breakdown for a day trip
The entry cost itself is tiny — DTPC Idukki lists ₹10 for adults and ₹5 for children. Most of your spend is transport and food. The table below is an indicative planning estimate for one person on a day trip from Thodupuzha (October 2026), assuming shared local transport and simple meals; it is not a live-verified quote and should be reconfirmed.
| Item | Indicative cost | Notes |
|---|---|---|
| Entry | ₹10 (adult) | DTPC Idukki listed rate; ₹5 for children |
| Local transport (round trip) | ₹150–₹600 | Bus is cheapest; shared taxi/auto higher; depends on group size |
| Food and water | ₹150–₹400 | Carry-in snacks plus a meal in Thodupuzha |
| Optional guided trek (share) | ₹300+ per head | ₹1,500 for five persons split; ₹250 per extra person |
| Rough total | ₹300–₹1,300 | Day trip, excluding stay and long-distance travel |
Fees, permits and rules
No special state permit (such as an inner-line permit) applies to Thommankuthu — it is an ordinary Forest Department eco-tourism site with an entry ticket, not a restricted zone. DTPC Idukki lists entry at ₹10 for adults and ₹5 for children, open all days from 8 am to 6 pm (as of October 2026 — reconfirm).
The guided trek is different: it requires pre-booking with the Forest Department, caps the group at nine, and runs only when weather allows. Because this is a reserve forest, follow the Forest Department’s instructions on where you may go, carry out all waste, and avoid plastic litter. Confirm any photography, drone or group-size rules with the range office before you travel.
Practical tips and safety
Safety is the single most important part of a Thommankuthu visit. Onmanorama’s 2018 field report says the site has witnessed several deaths and that visitors are advised to observe the rules strictly, and that the sudden surge of water that feeds the falls makes it dangerous in the rains. This matches the broader pattern in Idukki, where Onmanorama’s monsoon-safety coverage warns that rising water in the district’s rivers leads to drownings and accidents.
- Do not bathe when water is high or rising, especially in the monsoon; flows can surge with little warning. Stay off slippery upper rocks.
- Check weather first: watch India Meteorological Department (IMD) alerts for Idukki and skip the trip during heavy-rain or landslide warnings.
- Connectivity and cash: mobile network and UPI can be patchy in the forest belt; carry some cash and do essential calls/bookings from Thodupuzha.
- Medical help: the nearest hospitals are in Thodupuzha; there is no clinic at the falls, so carry a basic first-aid kit.
- Footwear and timing: wear shoes with grip, start early, and leave before the canopy darkens near closing.
- Solo and women travellers: the lower area sees regular footfall by day; for the upper trail and trek, go in a group and prefer the Forest Department guided option.
- Pack by season: rain jacket and quick-dry clothes in the monsoon; sun protection and extra water in summer.

How many steps does Thommankuthu have?
Thommankuthu is a seven-step cascade: Kerala Tourism calls it a “seven-step thundering cascade,” and DTPC Idukki says the water descends in seven distinct steps, each with its own pool. It is a series of linked falls rather than one sheer drop, which is why a short forest walk connects the steps.
Is the Thommankuthu trek open to everyone, and how do I book?
The organised Nakkayam–Thommankuthu trek is a 5 km Forest Department walk that must be pre-booked and is capped at nine people, per Kerala Tourism. It costs ₹1,500 for five persons plus ₹250 per extra person. Book through the Divisional Forest Office, Kothamangalam (+91 485-2822317); availability depends on weather.
What is the best time to visit Thommankuthu Waterfalls?
The monsoon (roughly June to September) gives the fullest flow, but it is also the most dangerous time for bathing and climbing. For a comfortable, safer visit choose the post-monsoon months, about October to January, when the falls still run strongly and the rocks are easier underfoot. Avoid visiting during heavy-rain warnings.
Is Thommankuthu safe to swim in?
Thommankuthu can be dangerous, and swimming is risky when water is high. Onmanorama reports the site has seen several deaths, with sudden water surges in the rains. Bathe only in calm, shallow pools when levels are low, never during or after heavy rain, follow posted rules, and keep children close at all times.
Last updated and sources
Thommankuthu suits anyone who wants a short, stepped forest cascade near Thodupuzha rather than a single big drop — families, day-trippers and walkers who will respect the water. Go in the post-monsoon months for the best mix of flow and safety.
