Dao Co Thanh Mien: A Traveler's Guide to Hai Phong's Egret Island

Dao Co Thanh Mien sits in the middle of a lake in Thanh Mien district — a flat, quiet corner of Hai Phong province that most travelers skip entirely. That's a shame, because this tiny island holds one of the largest wild bird colonies in northern Vietnam (베트남 / 越南 / ベトナム), with tens of thousands of egrets, storks, and cormorants nesting in a dense canopy of banyan and bamboo. It's not a zoo and it's not a park. It's a functioning ecological site that happens to welcome visitors.

What it is

The island covers roughly 1.5 hectares in the center of An Duong lake, surrounded by rice paddies and fish ponds. Locals have protected the bird colony here since the 1970s, and the site was formally recognized as a nature reserve. At peak season, somewhere between 15,000 and 20,000 birds roost on the island — storks, grey herons, pond herons, cattle egrets, and several species of cormorant.

The whole setup is low-key. A narrow footbridge connects the shore to the island, and a basic observation tower gives you a view over the treetops where the birds nest. There's no ticket booth with scanners, no audio guide, no gift shop. A caretaker family manages the site and collects a small entrance fee.

Why travelers go

Bird photography is the main draw. The sheer density of nesting birds on such a small island makes it easy to observe behavior you'd struggle to see elsewhere — feeding, mating displays, chicks calling from nests — all from 20 or 30 meters away. Even without a long lens, the spectacle of thousands of white egrets lifting off the canopy at dawn is worth the trip.

Beyond the birds, the area around Thanh Mien gives you a window into the Red River Delta's agricultural landscape. No tourist infrastructure, no souvenir stalls. Just fish ponds, rice fields, village temples, and the rhythms of a farming district that hasn't been reshaped by tourism.

Best time to visit

The colony is active year-round, but the best months are May through September. This is breeding season — the island is at maximum capacity, chicks are in the nests, and the noise and movement are constant. Early morning (before 7 AM) and late afternoon (after 4 PM) are the prime windows. That's when the birds leave and return in large flocks, creating those dramatic silhouette shots against the sky.

Avoid midday in summer — it's hot, the birds are mostly settled in the canopy, and the humidity around the lake is punishing. October through March is quieter; many migratory species have moved on, though resident egrets remain.

How to get there

From Hanoi, Thanh Mien district is about 90 km southeast — roughly two hours by car or motorbike via National Highway 5 and then cutting south through Hai Duong city.

• By motorbike: The most practical option for independent travelers. From Hanoi (하노이 / 河内 / ハノイ), take QL5 toward Hai Duong, then turn south on DT392 toward Thanh Mien town. The island is about 3 km east of the town center, signposted (look for "Dao Co"). Total ride: around 2–2.5 hours.
• By bus + xe om: Catch a bus from Hanoi's Gia Lam or My Dinh station to Hai Duong city (50,000–70,000 VND, about 1.5 hours), then hire a local xe om or taxi for the remaining 25 km south to the island (expect 150,000–200,000 VND one way).
• By car: Book a private car from Hanoi for a day trip. A round-trip hire typically runs 1,200,000–1,500,000 VND depending on your negotiation skills and whether you use a Grab rental or a local driver.

The entrance fee to the island is modest — around 20,000–30,000 VND per person.

What to do

1. Climb the observation tower at dawn

Get there before 6 AM if you can. The wooden observation tower on the island puts you just above canopy level. As the sun comes up, the storks and egrets begin leaving in waves — sometimes hundreds at a time. Bring binoculars or a telephoto lens.

2. Walk the island's perimeter path

A shaded trail loops around the island under the banyan trees. It's short — maybe 30 minutes at a slow pace — but it gets you close to nesting clusters. The caretaker can point out different species and nesting zones. Keep your voice down; the birds are tolerant of visitors but will relocate if you're loud.

3. Explore the surrounding fish ponds

The ponds ringing the lake are where many of the egrets feed. Walking or cycling the raised dikes between ponds at golden hour is peaceful and gives good photo opportunities of birds hunting in shallow water.

4. Visit Chi Le village

About 2 km from the island, Chi Le is a traditional weaving village. It's not tourist-oriented, but if you show up on a weekday morning, you'll see looms in action in front courtyards. A good excuse to stretch the visit beyond just the birds.

5. Cycle the rice paddies

If you're visiting May through July, the paddies are vivid green. Borrow or rent a bicycle from your guesthouse and ride the narrow paths between fields. The Red River Delta is pancake-flat, so it's easy riding.

Where to eat nearby

Thanh Mien town has a handful of "com binh dan" (rice-and-dish) stalls along the main road. The local specialty worth trying is "banh cuon" — thin steamed rice rolls filled with minced pork and mushroom, served with fried shallots and dipping sauce. Thanh Mien's version uses a particularly thin, almost translucent wrapper. A plate runs 25,000–35,000 VND.

For something heartier, look for "bun ca" — rice noodle soup with fried fish chunks, a common breakfast across Hai Duong and Hai Phong. Expect to pay around 30,000–40,000 VND.

If you're heading back through Hai Duong city, stop at one of the "banh dau xanh" shops — mung bean cakes are the city's signature sweet, and they make decent gifts.

Where to stay

Thanh Mien doesn't have much in the way of accommodation. Your options:

• Nha nghi (guesthouses) in Thanh Mien town: Basic but clean. Expect 200,000–350,000 VND per night. Air conditioning and hot water are standard; breakfast usually isn't.
• Hotels in Hai Duong city (25 km north): More variety, including mid-range hotels in the 400,000–700,000 VND range with proper amenities.
• Day trip from Hanoi: Most travelers treat this as a day trip, which is realistic if you leave early.

Practical tips

• Bring insect repellent. The lake and fish ponds mean mosquitoes, especially at dawn and dusk — exactly when you want to be there.
• Wear muted colors. Bright clothing can spook the birds at close range. Earth tones or dark greens help you blend in.
• Ask the caretaker before flying a drone. Drones stress nesting birds, and depending on the season, they may be prohibited. Don't assume it's fine.
• Carry cash. There are no ATMs near the island. The nearest reliable ones are in Thanh Mien town or Hai Duong city.
• Pack water and sunscreen. There's no shop on the island itself.

Common mistakes to avoid

• Arriving at noon and wondering where all the birds are. The colony looks half-empty in the middle of the day. Time your visit for early morning or late afternoon.
• Skipping the surrounding area. The island visit itself takes 1–2 hours. If you've driven 2 hours from Hanoi, build in time to explore the paddies and villages nearby — that's where the texture of the trip is.
• Expecting a polished eco-tourism experience. This isn't Tram Chim or a national park with boardwalks and bilingual signs. It's a community-managed site. The charm is in its roughness, but manage your expectations on facilities.

Practical notes

Dao Co Thanh Mien pairs well with a longer loop through the Red River Delta — combine it with a stop in Ninh Binh (닌빈 / 宁平 / ニンビン) or a day exploring Hai Phong's seafood scene. It's the kind of place that rewards patience and early alarms, not bucket-list rushing.
