This is the signature Alleppey cruise and the one most people have in mind when they book. You leave the Nehru Trophy Finishing Point, work out through the Punnamada channels, and come onto the open water of Vembanad — the largest lake in Kerala and the longest in India.
The shape of the route
You board at noon and the boat moves out almost immediately, with lunch served as you go. The first half hour is canal: houses on both banks, moored country boats, the jetty traffic thinning behind you.
Then the banks fall away and you are on open water. Vembanad runs roughly 96 kilometres from Alappuzha up towards Kochi, and although you will only see a fraction of it, the effect is immediate — the far shore becomes a low green line, the sky opens up, and there is usually a breeze that the canals do not get.
The afternoon is spent crossing and skirting that open water, often with a turn into the Kuttanad channels before the boat finds its mooring for the night.
What you see
- Fishing — stake nets strung across the shallows, small canoes working the margins, and the big cantilevered Chinese fishing nets on the Kochi side of the lake
- Other houseboats, which is part of the character of this route rather than a flaw; the lake is busy in a way the back canals are not
- Village shoreline — churches, temples, landings, coconut palms leaning out over the water
- Birds over open water: terns, kingfishers, the occasional osprey, and large flocks of cormorants
- The boat-race stretch on Punnamada, which is the water you depart from
The sunset
This is the route’s real argument. The boat anchors at 5:00 PM — Kerala requires houseboats to stop cruising then — and on this route it will usually moor with open water to the west.
Sunset over Vembanad, from a boat that has just gone quiet, is the photograph people come home with. The canal routes are more interesting during the day; this one is better at the end of it.
Which boats suit it
All of them. Open water imposes no size constraint, which is why the larger five, six and eight-bedroom boats spend most of their time on this route — they can cross the lake freely where they would struggle in the narrow channels.
If you are on a big boat, this is the route you will see most of.
When to come
November to February gives the clearest skies and the most reliable sunsets, and the lake is at its most photogenic. It is also the busiest.
June to September, the monsoon, puts dramatic weather over a lot of water — good for photographers, less good if you want a guaranteed golden hour.
March to May is hot, and the open stretch is exposed. The upper deck is unusable in the early afternoon without shade, which is the one time of year to pay for a boat with daytime air conditioning.
If the lake is not your thing
Some guests find open water less engaging than they expected — it is beautiful but there is less happening than in a village channel. If you want proximity and detail rather than scale, ask for more time in Kuttanad. If you want birds, the Pathiramanal loop goes to the island in the middle of this lake.

Common questions
Is the Punnamada–Vembanad route good for a first houseboat trip?+
It is the one we would put a first-timer on. It gives you the open water people picture when they picture Kerala, the best sunset of any route, and enough variety in an afternoon that nobody gets restless. Most cruises on it also dip into the village canals before mooring.
How big is Vembanad Lake?+
It is the longest lake in India and the largest in Kerala, running roughly 96 kilometres from Alappuzha up towards Kochi. You will see a fraction of it in an afternoon — enough that the far bank is a low green line rather than a shore.
Can the lake get rough?+
On a windy afternoon the open stretch can get choppy, in the way a large lake does. It is not uncomfortable on a boat this size and the captain will hug the shore if conditions warrant. Anyone prone to motion sickness will find the canal routes calmer.
Will I see the Nehru Trophy Boat Race course?+
Yes — you board at the finishing point, so the final stretch of the course is the water you leave from. During the race itself, traditionally the second Saturday of August, the lake is closed to tourist traffic and boats work around it.
