Anchuruli Tunnel Idukki Travel Guide

Anchuruli Tunnel in Idukki is a unique water tunnel and viewpoint hidden in the hills of Kerala. It is part of the Idukki dam catchment, where a 5.5 km long circular tunnel brings water from Erattayar Dam and releases it into the Idukki reservoir. When the water is flowing, it looks like a huge natural waterfall coming out of a cave.

The word Anchuruli means “five vessels”, referring to five small hills that look like inverted pots when reservoir levels are lower. This quiet place has slowly become a favourite among nature lovers, road trippers and photographers visiting Idukki, Thekkady and Vagamon.

Top Things To See In Anchuruli Tunnel Idukki

1. Anchuruli Tunnel Mouth and Waterfall Viewpoint

This is the main Anchuruli tourist place. From the parking area you walk down a short mud path through trees and reach the rocky banks of the Idukki reservoir. Here you see the huge circular tunnel mouth. In rainy season water thunders out like a powerful waterfall. In drier months, the flow is gentle and you can see more of the tunnel structure from outside.

• Distance from Kattappana: About 7 – 10 km by road
• Walk from parking: Around 5 – 10 minutes on an uneven path
• Ideal time at spot: 45 – 90 minutes
• Good for: Photos, videos, just sitting and watching the water

Hidden tip: Step back a little from the crowd and use zoom on your phone for photos. You get dramatic frames of the tunnel and waterfall without standing on slippery rocks near the water.

2. Idukki Reservoir and “Five Vessels” Hills

The wide Idukki reservoir itself is a beautiful attraction. When the water level is lower you can see five small hills that look like inverted vessels. This sight is the origin of the name Anchuruli. On clear days, the deep blue water and surrounding green hills are perfect for landscape photography.

• Best time: Post monsoon and winter months when the sky is clear
• Activities: Landscape photography, quiet sitting, short walks
• Duration: 30 – 45 minutes

Hidden tip: If the view looks hazy, wait for a light drizzle or shower. Once the rain stops the air becomes clear and distant hills look sharper in photos.

3. Small Hilltop Viewpoints Around Anchuruli

Above the reservoir, there are small hill slopes and grasslands that give a bird eye view of the water and tunnel area. Some of these viewpoints are close to the road, and some need a short walk. These spots are less crowded and very good for sunrise and sunset.

• Distance: 1 – 3 km stretch around Anchuruli on the hill roads
• Type: Roadside viewpoints and small trails
• Good for: Couples, photographers, older kids who can walk safely

Hidden tip: Ask a local tea shop owner for the nearest “nice viewpoint” for that day. Locals usually know small clearings and bends that give better views than the obvious tourist corner.

4. Lakeside Feel and Anchuruli Thuruthu Area

Even though there is no regular boating, the sides of the reservoir near the viewpoint give a peaceful lakeside feel. When the water is not very rough you can sit on safe high ground, enjoy the cool breeze, watch birds and feel like you are on a quiet backwater shore.

• Activities: Calm sitting, bird watching, nature observation
• Best time: Early morning or late evening
• Facilities: Only basic snacks and tea up near the parking

Hidden tip: Carry a small mat and sit a little away from the crowd on higher flat ground. You will enjoy the sound of water and wind much more than standing in a noisy group near the edge.

5. Movie Shooting Spots Around Anchuruli Tunnel

Anchuruli became famous after the Malayalam movie “Iyobinte Pusthakam” and some other films shot key scenes here. Fans will recognise the tunnel mouth, sloping rocks and reservoir view from those movies. Walking around the safe parts of this area gives you the feel of being inside those movie frames.

• Highlight: Same real tunnel face and rough landscape seen in films
• Photo spots: Flat rock slabs before the steeper wet rocks begin

Hidden tip: For a cinematic look, shoot short clips in slow motion from a safe distance while someone walks along the safe rocky path with the tunnel in the background.

Adventure Activities And Things To Do In Anchuruli Tunnel Idukki

Anchuruli is not a formal adventure park, but you can still enjoy light adventure and outdoor activities in a safe and responsible way. Most activities are based on walking, photography and nature appreciation rather than high thrill sports.

Fun Activity Spots For Kids In And Around Anchuruli

Anchuruli is not a typical children park, but kids can still enjoy the place if parents are careful.

• Short walk from parking to a safe viewpoint away from steep edges
• Throwing small stones into shallow puddles far away from the main water channel
• Watching birds, butterflies and clouds over the hills
• Simple picnic under shade on higher ground

For more child friendly attractions you can combine Anchuruli with:

• Thekkady: Boat ride in Periyar lake, elephant interactions, spice gardens
• Vagamon: Meadows, pine forest, small play zones
• Vaigai Dam side: Parks and light fountains (if you are looping via Tamil Nadu)

Hidden tip: For families with small kids, keep Anchuruli as a short scenic stop (1 – 1.5 hours) and make Thekkady or Vagamon the main highlight of the day.

Best Time To Visit Anchuruli Tunnel Idukki

Monsoon Season (June – September)

Water flow is strongest and the tunnel looks like a giant waterfall. Surrounding hills are lush and green.

• Pros: Most dramatic waterfall views, very green scenery
• Cons: Rocks are extremely slippery, water can rise suddenly, paths get muddy
• Who should go: Experienced travellers who are ready to stay far from the water and view everything from safe high points

Post Monsoon And Winter (October – February)

This is the best time to visit Anchuruli Tunnel for most tourists. Weather is cooler, water flow is still good, and the trail is easier.

• Pros: Pleasant climate, good visibility, safer paths compared to peak monsoon
• Cons: Weekends and holidays can get crowded

Summer (March – Early June)

Water flow reduces and sometimes you can see deeper into the tunnel from outside. Days can be warm.

• Pros: Easier walking, less mud, clearer sky for photos
• Cons: Waterfall may be thin, mid day heat can be tiring

Hidden tip: For a balance of safety, good water flow and comfortable climate, plan your trip to Anchuruli between October and February, and visit in the morning or late afternoon rather than mid day.

Anchuruli Tunnel Safety Tips

Anchuruli is beautiful but can be risky if people go too close to the water or tunnel. There have been accidents in the past. Follow these safety points very strictly.

• Never enter the tunnel. Water can be released from the dam without warning.

• Wear good shoes with grip. Avoid heels and slippery sandals.
• Hold children firmly near any sloping rock or edge.
• Do not visit after dark. There are no proper lights or railings and the area is close to forest.
• Watch for broken glass and litter on the rocks. Better to wear closed shoes.
• Follow sign boards and local warnings. If locals shout a warning, listen immediately.

Hidden tip: Before reaching the edge, set a “family safety line”. For example, decide that nobody crosses a particular tree or rock. This prevents people pushing closer for selfies.

Anchuruli Tunnel Traveller Reviews

🌞 The Good

⭐ ⭐ ⭐ ⭐ ⭐ “Hidden gem near Kattappana.” I loved that Anchuruli still feels like a quiet, offbeat place and not a crowded tourist spot. The short walk from the parking area opens to a huge tunnel, calm reservoir and misty hills, and for a moment it felt like we had stepped into a movie scene. Perfect for a slow morning with a flask of tea and a camera.

⭐ ⭐ ⭐ ⭐ ⭐ “Perfect photo spot for nature lovers.” If you enjoy photography and scenic places, this spot is heaven. In monsoon the water shoots out of the tunnel like a giant waterfall, and in winter you get clear views of the hills and reservoir. We spent more than an hour just trying different angles and long exposure shots – totally worth the detour.

⭐ ⭐ ⭐ ⭐ ⭐ “Calm picnic point, not commercial.” We visited as a family and really liked that there are no big shops or noisy loudspeakers here. Just a couple of tea stalls, some rocks to sit on and a cool breeze from the water. The kids enjoyed the mini walk and we enjoyed the silence and views. It felt like a simple, honest nature stop.

⭐ ⭐ ⭐ ⭐ ⭐ “Great add-on to an Idukki road trip.” We combined Anchuruli with Calvary Mount and Ayyappancoil hanging bridge in one day. Anchuruli was the most unique because of the tunnel and the five little hills in the reservoir. As a one-hour break between long drives it was perfect – stretch your legs, click some pictures and move on.

⭐ ⭐ ⭐ ⭐ ⭐ “Different face in every season.” I have seen Anchuruli twice now – once during the rains and once in summer. The first time it was all roaring water and mist; the second time the flow was smaller and we could see deep into the tunnel from outside. It is amazing how the same place can look completely different yet equally beautiful.

⭐ ⭐ ⭐ ⭐ ⭐ “Peaceful escape close to town.” We were staying in Kattappana and wanted a nearby evening spot. Anchuruli was just a short drive away, but the moment we reached it felt far from town life. Sitting quietly on the higher rocks, watching the sun go down over the reservoir, was one of the most relaxing parts of our Idukki trip.

❄️ The Not So Good

⭐ ⭐ ⭐  “Safety can be an issue if you are careless.” The place is naturally rocky and slippery, and there are only limited railings. We saw some people trying to walk inside the tunnel and going right up to the edge, which looked very risky. With proper caution Anchuruli is wonderful, but families with small children and elderly people must be extra careful.

⭐ ⭐  “Very basic facilities, so plan ahead.” Apart from a couple of stalls selling tea and snacks there is almost nothing here. No proper restaurant, limited toilets and a small parking space. It was fine for us because we came prepared, but travellers expecting a fully developed tourist centre may feel disappointed.

⭐ ⭐ “Can get crowded and messy on holidays.” On weekends the narrow path and rocks fill up quickly, and sadly not everyone respects the place. We noticed plastic bottles and chips packets thrown around, and some noisy groups spoiling the peaceful vibe. Visiting early in the morning or on a weekday is definitely better.

⭐ ⭐ ⭐  “Long drive for a short stop if it’s your only plan.” If you come all the way only for Anchuruli, you might feel the actual time at the spot is short – mostly views and photos for an hour or so. For us it made sense only because we clubbed it with other Idukki attractions; as a stand-alone destination it may feel a bit limited.

Final Travel Tips For Anchuruli Tunnel Idukki

• Keep Anchuruli as a 2 – 3 hour stop, not the only activity of the day.
• Combine it with Calvary Mount, Ayyappancoil bridge or Idukki dams for a full day itinerary.
• Wear shoes with good grip and avoid going near slippery wet rocks.
• Never enter the tunnel, even if you see other people doing it.
• Carry water, snacks, basic medicines and your own trash bag.
• Plan to exit the area before dark.

If you are looking for a raw, less crowded place with strong natural beauty, Anchuruli Tunnel Idukki is a great stop to include in your Kerala hill vacation. Visit safely, respect the water and the hills, and the place will reward you with unforgettable views.
