About Kanwar Lake (Kabartal) and quick facts
Kanwar Lake (Kabartal) is a freshwater oxbow lake in Begusarai district, Bihar, and the state’s first wetland on the Ramsar List of Wetlands of International Importance. According to the Ramsar Sites Information Service, the site (number 2436) was designated on 21 July 2020 and has an official listed area of 2,620 hectares.
The lake is a residual oxbow, a cut-off river meander, linked to the Burhi Gandak river in the Indo-Gangetic floodplain. Bihar Tourism describes it as drawing water from the confluence of the Gandak, Baya and Kareh rivers. It is widely described as Asia’s largest freshwater oxbow lake, a claim you will see on the Bihar Tourism and district pages.
Do not confuse this Kanwar Lake with the Kanwar or Kanwarbhog areas elsewhere in India; the Bihar site is specifically Kabar Taal, near Manjhaul in Begusarai. In national conservation records the surrounding area is also known as the Kanwar Jheel bird sanctuary.

Best time to visit Kanwar Lake
The best time to visit Kanwar Lake is the cool, dry winter from roughly November to March, when migratory waterbirds are present and the weather is comfortable for being out on the water. The official Bihar Tourism page lists September to April as the visiting window for the site.
Summer (April to June) in the Gangetic plains is hot and birdlife is thin. The monsoon (June to September) raises water levels across the floodplain, and the Ramsar record notes the wetland floods during the monsoon. Roads and field tracks around the lake can be difficult then.
| Season | Months | What to expect |
|---|---|---|
| Winter | November–March | Best period; migratory birds, cool mornings, calm water. Carry warm layers. |
| Spring/early summer | April | Warming up; birds thinning out; still within the official window. |
| Summer | May–June | Hot and dry; low water; least rewarding for birding. |
| Monsoon | July–September | High water, flooding across the floodplain; access harder. |
How to reach Kanwar Lake from Patna and Begusarai
The practical way to reach Kanwar Lake is to get to Begusarai by train or road, then travel the last roughly 22 km north-west to the lake near Manjhaul by taxi or bus. The lake is not a ticketed gated park, so local transport and a guide matter more than any entry gate.
By air: The nearest airport is Lok Nayak Jayaprakash Airport in Patna. The Begusarai district administration states the district is about 124 km from Patna, reachable by bus and car. From the airport, hire a taxi or take a train onward to Begusarai.
By rail: Begusarai is the nearest major railway hub. The district administration lists direct trains to and from Patna including the Koshi Express, an Intercity Express and the Rajya Rani Express; reconfirm current train names and numbers on IRCTC or NTES before booking.
By road: Begusarai is connected by state and national highways and by regular buses from other Bihar cities. From Begusarai town, private taxis and local buses run towards Manjhaul; use a map app for the final stretch to the lakeshore.
| From | Distance | Typical mode |
|---|---|---|
| Begusarai town | About 22 km | Taxi or local bus to Manjhaul |
| Patna (city/airport) | About 124 km (district figure) | Train to Begusarai, then road |
| Patna by rail to Begusarai | Direct trains available | Koshi/Intercity/Rajya Rani (reconfirm) |
Birdlife and things to do
The main reason to come to Kanwar Lake is winter birdwatching along the Central Asian Flyway. The Ramsar record notes the wetland supports about 58 migratory waterbird species as a wintering and stopover site, with 221 bird species recorded in total across the wider area.
The ornithologist Salim Ali recorded around 106 resident bird species and about 60 migratory species here, figures still widely cited for the sanctuary. You can expect ducks, geese, waders and other waterbirds over the open water and marsh edges; a local guide will help you find and name them.
Beyond birding, the lake is explored by boat, and a boatman can take you across the open water and reed beds. The lake sits in a working rural landscape, so you will see fishing and farming around its margins; treat residents and their livelihoods with respect rather than as sights.
| Activity | Notes | Time needed |
|---|---|---|
| Winter birdwatching | Best at dawn; bring binoculars and a local guide | 2–4 hours |
| Boat ride on the lake | Hire a local boatman; agree the price first | 1–2 hours |
| Jaimangla Garh visit | Island shrine area near the lake (Chandi Sthan) | 1–2 hours |
| Photography | Phones and cameras allowed per Bihar Tourism | Flexible |
Suggested itinerary
A focused one-day trip works well if you are based in Patna or Begusarai; add a night in Begusarai if you want an unhurried dawn on the water.
- Day 1 (half or full day): Reach the lake near Manjhaul by mid-morning from Begusarai. Take a boat ride, spend time birdwatching at the quieter margins, and visit the Jaimangla Garh shrine area nearby. Return to Begusarai by evening.
- Optional overnight: Stay in Begusarai town. Start before sunrise the next day for the best light and bird activity, then continue your onward journey.
If you are building a wider Bihar trip, this pairs naturally with a broader itinerary from our Bihar travel guide, and with the Buddhist circuit covered in our Bodh Gaya guide.
Where to stay
There is no documented tourist lodge at the lake itself, so most visitors stay in Begusarai town, about 22 km away, and make a day trip. Begusarai has budget and mid-range hotels; options and tariffs change, so book ahead in winter and confirm current rates directly.
The ranges below are indicative planning estimates, not quoted tariffs, and should be reconfirmed with the property at the time of booking.
| Type | Where | Indicative per night |
|---|---|---|
| Budget | Begusarai town guesthouses/hotels | ₹800–₹1,500 (estimate, reconfirm) |
| Mid-range | Begusarai town hotels | ₹1,500–₹3,000 (estimate, reconfirm) |
| Higher-end | Limited; check Patna for more choice | ₹3,000+ (estimate, reconfirm) |
For a wider choice of hotels and better connectivity you can also base yourself in Patna and make a longer day trip, though that means more road and rail time.
Food to try
Food around Kanwar Lake is simple, home-style Bihari cooking; eat in Begusarai town where there are more options. Carry your own water and snacks for the lakeside, as facilities there are basic.
- Litti-chokha (roasted wheat-and-gram-flour balls served with mashed spiced vegetables) — Bihar’s signature dish.
- Sattu (roasted gram flour) drinks and stuffed parathas — a cooling, filling staple.
- Dal-bhat-tarkari (lentils, rice and vegetable curry) — the everyday meal.
- Khaja and thekua (crisp, sweet flour-based snacks) — local sweets you will see in markets.
Budget breakdown
A trip to Kanwar Lake can be inexpensive because the lake has no documented entry fee and most costs are transport, a boat and one night’s stay. The figures below are indicative planning estimates for one person on a short trip and should be reconfirmed before you travel.

Permits and rules
No special permit such as an Inner Line Permit applies to Kanwar Lake, and no entry ticket for the wetland is documented on the official pages reviewed. As a Ramsar site and notified bird sanctuary, though, it is a protected area, so ordinary wildlife and wetland conduct rules apply.
Bihar Tourism states that mobile phones and cameras are allowed, and asks visitors to respect wildlife and not feed the birds. Do not disturb nesting or resting flocks, avoid loud noise, and carry your litter out. If you plan drone photography, confirm permissions locally and follow national DGCA drone rules, as protected areas can be restricted.
Practical tips
- Guide and boat: Arrange a local guide and boatman in advance through your hotel in Begusarai; agree prices before you set off.
- Cash: Carry enough cash, as UPI and card acceptance near the lake is unreliable; draw money in Begusarai town.
- Timing: Start at dawn for the best bird activity and light; the midday lake is quiet.
- Health: The nearest hospitals are in Begusarai town; carry basic medicines, sunscreen and drinking water.
- Solo women travellers: Begusarai is a small town; travel in daylight, use pre-arranged transport, and keep someone informed of your plans.
- Packing: Winter mornings are cold near water, so bring warm layers; add binoculars, a hat and insect repellent year-round.
