Hai Phong is the city many Cat Ba buses drive straight through, and skipping it costs you at least one good meal. Vietnam's big northern port has a compact French-era center, a food culture the city is proud of and boats to Lan Ha Bay from its own pier. It is not a sightseeing heavyweight like Hanoi or Hue. Give it one night, eat well, walk the old center in the morning, then take the catamaran to Cat Ba or the road to Do Son.
How we built this guide: on 19 October 2026 we checked Vietnam Railways' timetable and fares for 5 November 2026, bus listings on Vexere and ferry listings on Baolau, hotel prices on Booking.com for 5 November, Grab's Cat Bi airport page, Numbeo's price survey, city and national press reports from 2017 to 2026 on the merger, the post office, food, the flamboyant festival and Do Son, a Vietnam Airlines magazine feature, a VinWonders visitor guide and Wikipedia's entries and climate table. We did not visit Hai Phong for this update.
Is Hai Phong worth a night, or only a transit stop?
It is worth one night for most people heading to Cat Ba, and a second only if you want Do Son or a slower food crawl. The city works best as a base between Hanoi and the bay, with an evening of street food and a morning in the old center.
| Plan | What you get | Who it suits |
|---|---|---|
| Pass straight through on a Hanoi to Cat Ba bus | The fastest way to the island; no time in the city | Travelers short on days |
| One night in the center | Opera House, post office and museum on foot, banh da cua, the 06:00 catamaran to Cat Ba | Food lovers, rail travelers |
| Two nights | Adds a half day at Do Son beach or a longer food crawl | Slow travelers, festival visitors |
If the bay is your only goal, our Hanoi to Cat Ba guide shows the through tickets that skip the city entirely.
What changed when Hai Phong merged with Hai Duong?
The city got much bigger on paper, but the part visitors use is the same. National Assembly Resolution 202/2025/QH15 of 12 June 2025 merged Hai Duong province into Hai Phong, per Wikipedia. Vietnam's tourism authority puts the new city at 3,194.72 km² with 4,664,124 people (vietnam.travel), while a June 2026 city report gives about 3,184.5 km² and more than 4.6 million (Hai Phong News).
Vietnam Briefing counts 114 commune-level units: 67 wards, 45 communes and 2 special zones. Cat Ba sits in one of those, the Cat Hai special zone. In practice, expect both old district names (Ngo Quyen, Le Chan, Hong Bang) and new ward names on hotel listings and maps. The train from Hanoi now also stops at Hai Duong station inside the enlarged city, though the old port center is still 45 km further down the line.
What is there to see in the French-era center?
A cluster of colonial buildings within an easy walk, led by the Opera House. Distances below are from the Opera House, per VinWonders, except the post office, which stands beside the Hoang Van Thu bridge.
| Building | Built | Distance from the Opera House | Why go |
|---|---|---|---|
| Opera House (Municipal Theater) | 1904 to 1912 | Start here | The city's landmark on its main square |
| Hai Phong Cathedral | Not stated in our sources | About 450 m | Gothic church with a 28 m bell tower |
| Hai Phong railway station | 1902 | About 750 m | Yellow colonial facade, trains to Hanoi |
| Hai Phong Museum | Not stated in our sources | About 750 m | The city museum, one of the old center's landmark buildings |
| Central post office | 1905 | About 1.3 km, beside Hoang Van Thu bridge | Classic French arches and a clock gable |
The Opera House
The Opera House is a French neoclassical theater built from 1904 to 1912 on what is now Opera Square, on land cleared from an old market, according to Wikipedia. It is also a revolutionary site: the Viet Minh held their first public meeting in the city there on 23 August 1945, and in November 1946, 39 Viet Minh soldiers and opera staff held the building against French troops for three days and nights. VinWonders says it was recognized as a national relic in 2015 and has a 400-seat hall over two floors.
You can go inside for performances, but our sources give no regular opening hours for casual visits. VinWonders lists house rules: respectful dress, no food, and no photography or recording without the management's consent.
The post office and the riverside
The central post office is the most photogenic of the group. Bao Hai Phong reported in October 2025 that the French built it in 1905, that it sits between Nguyen Tri Phuong and Hoang Van Thu streets beside the new Hoang Van Thu bridge, and that floor tiles replaced in a 2019 renovation were made to match the originals. With the Opera House, the museum and the State Bank building, it forms the core of the old city's architecture. VinWonders adds that the bridge has an LED light display at night.
Tip: Walk the center early in the morning, before the heat and the traffic, then end at the post office and cross toward the river.
What should you eat in Hai Phong?
Start with banh da cua, the dish the city is proudest of. Viet Nam News called it the city's pride, as pho is to Hanoians, and described wide reddish-brown rice noodles, crab, a pork-bone broth and optional toppings such as pork balls, fish cake and pork wrapped in la lot leaves, sold from dawn to midnight.
| Dish | What it is | Where our sources point you |
|---|---|---|
| Banh da cua | Crab noodle soup with wide red-brown rice noodles | Ba Cu on Cau Dat street (Heritage); 48 Lach Tray, 15:00 to 23:00 (VnExpress) |
| Nem cua be (nem vuong) | Square crab spring rolls with shrimp, pork, mushrooms and glass noodles, eaten hot | Cat Bi and Co Dao markets (Heritage) |
| Banh mi pate | Small, dense bread rolls with pate, chi chuong chili sauce and pickles | Near the Cot Den market crossroads, 19:00 to 03:00 (VnExpress) |
| Nom sua do | Red jellyfish salad with a sour sauce called bong | Early summer to late June only (Heritage) |
| Banh da xao gion | Rice noodles fried crisp on a cast-iron pan with beef and greens | 1 Le Chan street, 18:00 to 02:00 (VnExpress) |
The VnExpress shop details date from December 2023 and the Heritage feature from July 2023, so check that a stall is still open before you cross town for it. Street meals are cheap: Numbeo's survey puts a meal at an inexpensive restaurant at about 40,000 VND. For the rest of the country, see what to eat in Vietnam.
When do the flamboyant trees bloom?
In May, when the city turns red. Viet Nam News calls Hai Phong the city of the red flamboyant and names the streets around the Opera House, including Hoang Van Thu, Dinh Tien Hoang, Quang Trung, Tran Phu and Lach Tray, plus Tam Bac Lake, as the places people go to see the flowers. Local elders say the French brought the tree from Madagascar about a century ago. The Pham Van Dong road toward Do Son holds the Vietnamese record for flamboyant trees, with nearly 4,000.
The Red Flamboyant Festival marks the season and the city's liberation anniversary on 13 May. It was first held in 2012, and a March 2026 plan put this year's edition at 9 to 15 May (Bao Hai Phong). A report on 7 May said it would open on 8 May and run to the end of the month, with 20 city-level events and 40 local activities (Bao Dong Thap). Book rooms early for that fortnight.
Is Do Son beach worth the trip?
Yes for a half day by the sea or the buffalo festival, no if you expect clear water. Do Son is about 21 km south of central Hai Phong, 30 to 40 minutes by taxi or ride-hailing car, per Local Vietnam. Sun Paradise Land, Sun Group's own site, describes three beach zones:
- Zone I: closest to town, with mid-range hotels and restaurants, and the busiest.
- Zone II: a wide beach with upmarket resorts, and quieter.
- Zone III: by the casuarina forest, wilder and best for picnics.
The same guide warns that silt from the Lach Tray and Van Uc river mouths makes the sea slightly murky, and it suggests Bao Dai's French-style villa on a hill and the small island of Hon Dau, with its century-old working lighthouse. It quotes 250,000 to 300,000 VND for a taxi from Hai Phong.
The buffalo fighting festival
Do Son's famous festival peaks on the 9th day of the 8th lunar month, with ceremonies across that month and qualifying rounds earlier in summer, per Local Vietnam. In 2026 the final was set for 7:30 on 19 September at the Do Son ward central stadium, Bao Hai Phong reported. Entry rules change from year to year, so check the current arrangements, arrive early and stay behind the barriers.
How do you get to Cat Ba and Lan Ha Bay from Hai Phong?
Take the catamaran from Ben Binh pier in the city center. On Baolau for 24 October 2026, boats left at 06:00, 07:40, 09:00, 12:10, 14:10 and 15:50, taking 1 hour 30 minutes to Mot Thang Tu street in Cat Ba town for 170,000 VND. The road alternative crosses the Tan Vu to Lach Huyen sea bridge to Cat Hai island and the Dong Bai ferry; our Hanoi to Cat Ba guide explains both, and the Cat Ba and Lan Ha Bay guide covers the island, fees and boat trips.
Watch out: storms close the crossings. When Storm Narra approached in August 2026, the Dong Bai to Cai Vieng ferry was suspended and tourist boats stopped, DTiNews reported. From June to October, keep a spare day.
If you want limestone karsts without the island, Ha Long Bay and the quieter Bai Tu Long Bay are across the provincial line in Quang Ninh.
How do you get to Hai Phong, and around it?
From Hanoi, take the train for a central arrival or a bus for frequency; from the south, fly to Cat Bi. Vietnam Railways' timetable for 5 November 2026 shows four trains taking 2 hours 25 minutes to 2 hours 45 minutes, with soft seats from 124,000 VND, and Vexere lists 24 bus companies on the route. Our Hanoi to Hai Phong guide has the timetables, pickup points and car prices.
Cat Bi International Airport became international in May 2016, when a new terminal and a 3,050 m runway opened, and handled about 2.7 million passengers in 2023, per Wikipedia. Vietnam Briefing reports work on a second terminal. A Grab car to the center covers about 6 km in about 20 minutes for 80,000 to 120,000 VND, according to Grab; our airport transfer report compares the city buses. In town, ride-hailing covers most hops; see Grab and taxis in Vietnam.
Where should you stay?
Stay in the old center near the Opera House unless you came for the beach. On Booking.com for the night of 5 November 2026, 53 of 252 listed properties in Hai Phong were within 1 km of the center.
| Base | Best for | Trade-offs |
|---|---|---|
| Old center, near the Opera House | Walking the colonial buildings, food, the station and Ben Binh pier | City traffic and noise |
| Near the railway station | Early or late trains | Fewer restaurants than the main square |
| Do Son | Beach time and the buffalo festival | 30 to 40 minutes from the center |
| Cat Ba town | Lan Ha Bay boats | A boat ride away; storms can cut you off |
How much does Hai Phong cost?
Day-to-day costs are modest, as the table shows. Prices were checked on 19 October 2026, and we convert at 26,080 VND to US$1, Vietcombank's selling rate that day.
| Item | VND | About US$ | Source |

Booking.com's nine five-star listings that night ran from Wink Hai Phong Centre at 1,050,000 VND to the Pullman Hai Phong Grand Hotel at 2,700,000 VND, with the Mercure at 1,572,500 VND. Numbeo notes that its Hai Phong figures come from only 16 contributors, so treat them as a rough guide. For a whole trip, see what a Vietnam trip costs.
When is the best time to visit Hai Phong?
October, November and spring are the easy months; May brings the flowers and the heat; summer brings storms. The climate table on Wikipedia, citing the Vietnam Institute for Building Science and Technology, shows the pattern at Phu Lien.
| Months | Rain a month | Average high | What to expect |
|---|---|---|---|
| December to March | 23 to 49 mm | 19.8 to 22.2°C | Cool and gray, lows around 14 to 18°C |

Limitations
Hotel and transport prices are listings seen on 19 October 2026 for single dates, and they move with weekends, holidays and the May festival. Restaurant tips come from 2017 and 2023 features, so some stalls may have moved or closed. We found no regular public opening hours for the Opera House, so plan to see it from the square or at a performance. Building dates for the cathedral and the museum were not in the sources we read. Area and population figures for the merged city differ slightly between official sources. The Do Son festival date follows the lunar calendar and moves every year, and storms can stop every boat to Cat Ba from June to October at short notice. Climate figures are long-term averages.
