Kerala’s dams are more than structures built to store water and generate power. Across the state, reservoirs sit between forest-covered mountains, tea plantations, wildlife habitats, and quiet valleys, creating some of the most scenic landscapes to discover on a road trip.
From the dramatic mountains surrounding Idukki Dam to the island-dotted reservoir of Banasura Sagar, each destination offers a different experience. Some are ideal for boating and family outings, while others are better suited to wildlife, photography, or simply enjoying the landscape.
If you’re looking to explore Kerala beyond its famous beaches, backwaters, and hill stations, these seven scenic dams are worth adding to your itinerary.
1. Idukki Dam – Where Engineering Meets the Mountains
Few dam landscapes in Kerala are as dramatic as Idukki Dam. Set between the Kuravan and Kurathi hills, the imposing arch structure rises above a vast reservoir surrounded by the rugged mountains of Idukki.
The dam forms part of the Idukki Hydroelectric Project, making it an important part of Kerala’s power infrastructure. For travellers, however, it is the combination of engineering and mountain scenery that makes the destination memorable.
The wider area offers several ways to experience the landscape. Idukki Wildlife Sanctuary surrounds parts of the reservoir and adds a wildlife dimension to the journey, while nearby Calvary Mount offers expansive views across the reservoir and surrounding hills.
Rather than visiting Idukki Dam as an isolated attraction, consider making it part of a wider Idukki itinerary that includes the region’s forests, viewpoints, and high-range landscapes.
Best for: Mountain scenery, photography, engineering enthusiasts, and Idukki sightseeing.
2. Banasura Sagar Dam – A Reservoir Beneath the Wayanad Hills
In Wayanad, the landscape around Banasura Sagar Dam feels completely different from the rocky surroundings of Idukki.
The reservoir stretches beneath the dramatic Banasura Hills, with green mountains rising around the water and small islands appearing across the reservoir. The combination of water and mountain scenery makes it one of Kerala’s most striking dam landscapes.
Banasura Sagar is also one of India’s best-known earthen dams, although the exact ranking used to describe it varies between sources. Rather than relying on an uncertain superlative, the dam’s setting is reason enough to include it on a Wayanad itinerary.
Visitors can enjoy boating and explore the surrounding landscape, while trekking opportunities in the Banasura Hills provide a different perspective of the Western Ghats.
The dam works particularly well as part of a wider Wayanad trip, with Kalpetta, Padinjarathara, and other Western Ghats destinations accessible from the surrounding region.
Best for: Boating, photography, trekking, and Wayanad road trips.
3. Mattupetty Dam – A Scenic Stop in Munnar's High Ranges
Few dam destinations fit so naturally into a hill-station itinerary as Mattupetty Dam.
Located near Munnar, the reservoir is surrounded by rolling hills, tea plantations, forests, and the characteristic high-range landscape of Idukki. The calm waters of Mattupetty Lake provide a striking contrast to the green mountains around it.
Boating is one of the popular experiences here, while the surrounding area offers plenty of opportunities to stop and enjoy the scenery.
Mattupetty can easily be combined with other popular Munnar attractions. Echo Point, Kundala, and Top Station are part of the wider sightseeing circuit, allowing travellers to turn a visit to the dam into a full-day mountain excursion.
The surrounding forests also make this an interesting area for nature lovers, with opportunities to spot wildlife depending on local conditions.
Best for: Munnar sightseeing, boating, families, and mountain photography.
4. Malampuzha Dam – Where a Reservoir Meets Art and Recreation
Just outside Palakkad, Malampuzha Dam offers a different kind of experience. Here, the reservoir forms part of a larger recreational destination combining gardens, art, leisure attractions, and views towards the surrounding hills.
The Malampuzha Garden has traditionally been one of the area’s major attractions. Visitors can also explore the Rock Garden, created using discarded materials, and the famous Malampuzha Yakshi sculpture by artist Kanayi Kunhiraman.
The destination is particularly suitable for families because there is more to see than the dam itself. The surrounding attractions make it possible to spend several hours exploring rather than simply stopping for a photograph.
Travellers visiting Palakkad can also combine Malampuzha with Palakkad Fort and other attractions around the district.
Best for: Families, recreation, art, and Palakkad sightseeing.
Good to know: Visitor facilities and attraction access can change, so check current local information before travelling.
5. Neyyar Dam – Where the Reservoir Meets the Forest
Further south, Neyyar Dam offers a peaceful combination of water, mountains, and forest.
Located in Thiruvananthapuram district, the dam and reservoir are closely associated with the surrounding Neyyar Wildlife Sanctuary. Forest-covered hills give the destination a distinctly different atmosphere from the more developed recreational dam sites.
The wider Neyyar area provides opportunities for boating and nature experiences, while the sanctuary offers opportunities to explore the region’s wildlife and forest environment.
For travellers interested in combining a scenic water body with the natural landscapes of southern Kerala, Neyyar makes a worthwhile addition to an itinerary through the eastern parts of Thiruvananthapuram district.
Best for: Wildlife, nature, peaceful outings, and exploring southern Kerala.
6. Thenmala Dam – Where the Reservoir Becomes an Eco-Tourism Experience
At Thenmala in Kollam district, the dam is part of something much bigger.
The forests and hills of the Western Ghats surround the Thenmala Dam and its reservoir. The area forms part of Thenmala Eco-Tourism, which brings together nature, leisure, and adventure experiences.
Visitors can enjoy the reservoir landscape and explore attractions within the wider eco-tourism destination. The surrounding forests and hills make Thenmala particularly appealing to travellers who want to combine a scenic drive with outdoor activities.
The region also provides access to attractions such as Palaruvi Waterfalls, making it possible to build a full-day or weekend itinerary around Thenmala.
For travellers interested in nature-focused tourism, Thenmala offers more than a dam viewpoint—the reservoir becomes part of a larger experience built around the surrounding landscape.
Best for: Eco-tourism, nature, adventure activities, and weekend trips.
7. Bhoothathankettu – A Dam Surrounded by Forest and Folklore
Some Kerala destinations are memorable because of their scenery. Bhoothathankettu is memorable for both its landscape and its legend.
Located near Kothamangalam in Ernakulam district, Bhoothathankettu is associated with a local story about supernatural beings attempting to block the Periyar River. The legend gives the destination a character that goes beyond its physical landscape.
Today, the area is surrounded by forests, rocky terrain, and the waters of the Periyar. Boating and nature experiences are among the activities associated with the destination.
One of its biggest advantages for travellers is its proximity to Thattekkad Bird Sanctuary, also known as the Salim Ali Bird Sanctuary. Combining the two makes particularly good sense for birdwatchers and nature lovers looking for a short escape from Kochi.
Best for: Birdwatching, nature, folklore, boating, and weekend trips from Kochi.
Other Dams Worth Exploring in Kerala
These seven are only a starting point for travellers interested in Kerala’s reservoirs and mountain landscapes. Depending on your route, you can also explore:
- Kakkayam Dam – surrounded by forests and mountain scenery in Kozhikode district.
- Pazhassi Dam – a scenic reservoir destination in Kannur.
- Peruvannamuzhi Dam – known for its reservoir and surrounding natural landscape.
- Malankara Dam – near Thodupuzha, with recreational opportunities around the reservoir.

- Kulamavu Dam – another important part of the Idukki reservoir system.
- Aruvikkara Dam – a popular destination near Thiruvananthapuram.
- Vazhani Dam – a reservoir destination surrounded by the greenery of Thrissur district.
You don’t need to visit all of them. Choosing one or two that naturally fit your route can turn an ordinary road trip into a much more interesting journey.
Best Time to Visit Kerala's Scenic Dams
The ideal time depends on the experience you’re looking for.
October to March generally offers comfortable conditions for sightseeing, road trips, and outdoor activities across many parts of Kerala.
The monsoon season, roughly from June to September, gives the Western Ghats a completely different appearance. Forests become intensely green, streams fill, and waterfalls around the reservoirs can become much more dramatic.
However, heavy rainfall can affect road conditions, boating, trekking, and access to certain attractions. Check the local weather and visitor information before travelling during periods of heavy rain.
Tips for Visiting Kerala's Dams
A little planning can make these destinations much easier to enjoy.
- Check current opening hours and access conditions before travelling.
- Don’t assume boating or other activities operate every day.
- Follow instructions from the Kerala Forest Department when visiting protected areas.
- Stay away from restricted dam infrastructure and water-control areas.
- Carry drinking water and essentials, especially for remote destinations.
- Avoid leaving plastic or other waste behind.
- Start early if you’re combining a dam with several nearby attractions.
- During the monsoon, check road and weather conditions before setting out.
A Different Way to Discover Kerala
Kerala’s dams reveal a side of the state that is easy to overlook when a trip focuses only on beaches, backwaters, and famous hill stations.
At Idukki, engineering and mountain scenery come together. Banasura Sagar brings the Wayanad hills and a vast reservoir into one striking landscape, while Mattupetty places visitors in the middle of Munnar’s tea country. Malampuzha combines a reservoir with gardens and art, Neyyar brings water and wildlife together, and Thenmala turns a dam landscape into an eco-tourism experience. At Bhoothathankettu, meanwhile, forests, the Periyar River, and local folklore create a destination with its own distinctive character.
That variety is what makes Kerala’s dams worth exploring. They aren’t simply places to stop, take a photograph, and leave. They are gateways to the state’s mountains, forests, rivers, wildlife, culture, and engineering heritage—and sometimes, the road to the dam becomes just as memorable as the destination itself.
