Hong Kong to Mainland China: Every Border Crossing Explained (2026)

A HK$65 shuttle bus crosses a 55-kilometer sea bridge. A 14-minute train ride drops you from Kowloon into Shenzhen. And at 2 AM, exactly one land border between Hong Kong and the mainland is still open. Pick the wrong crossing and you lose an afternoon. Pick the right one and you barely notice you changed jurisdictions.

There are nine operational land and rail crossings between Hong Kong and mainland China as of 2026-07, plus ferries. They do not work the same way: Huanggang never closes, Shenzhen Bay clears both borders in one building, and Lo Wu feeds straight into the Shenzhen metro. This guide goes through each crossing in turn, with its hours, its fares, and the specific thing that catches people out.

One border, two immigration systems

This is the part that trips people up. Hong Kong and the mainland run separate immigration systems. Hong Kong is part of China, yet the trip from Kowloon to Shenzhen counts as an international crossing.

• Hong Kong to the mainland: you clear Hong Kong exit immigration, then mainland entry immigration. You need a Chinese visa unless you qualify for a transit waiver.
• Mainland to Hong Kong: you clear mainland exit immigration, then Hong Kong entry. You need valid Hong Kong entry rights.

Hong Kong grants visa-free visits to many nationalities. US passport holders may visit for up to 90 days, per the Hong Kong Immigration Department’s visa-policy table; other passports carry different allowances, so confirm your own figure on that page before you build a trip around it. The mainland still requires a visa, obtained before you travel. Your China visa does not cover Hong Kong, and your Hong Kong visa-free entry does not cover the mainland. The two do not talk to each other.

One warning worth repeating. A China visa is only good for the number of entries printed on it, and once all entries are used up, the visa is no longer valid. A single-entry visa is spent the moment you exit to Hong Kong. Cross to Hong Kong and try to return, and you are turned away unless you hold a double-entry or multiple-entry visa. Read the entries field on your visa before you build a hop-across itinerary, and ask the issuing Chinese embassy or consulate if anything on it looks ambiguous.

Side-by-side: which crossing does what

Start with the table. The details for each crossing follow below.

Hours shift during public holidays, and several crossings extend overnight for Lunar New Year and National Day. Verify current hours at the HK Immigration Department control points page and the Shenzhen government checkpoints page as of 2026-07 before you go.

The land crossings, ranked by usefulness

1. Lo Wu / Luohu (罗湖): the original crossing

Lo Wu is the original crossing and still the busiest on foot. The MTR East Rail Line terminates right at immigration. You get off the train, follow the signs, and you are in the queue. On the mainland side you walk out into Luohu, one of Shenzhen’s oldest districts.

• Hours: 6:30 AM to midnight daily
• Getting there: MTR East Rail Line to the Lo Wu terminus
• Mainland port: Luohu Port
• Good for: first-timers, budget travelers, anyone staying in Luohu
• Avoid: Monday 7 to 9 AM (commuters heading into Hong Kong), Friday 5 to 8 PM (the weekend rush out of Shenzhen)

The walk from the MTR gate to the mainland immigration hall takes 10 to 15 minutes. It is covered, air-conditioned, and well signed. On a calm day the whole crossing takes 20 minutes. On a Friday evening it can pass an hour.

The big advantage is the connection. Luohu Port feeds straight into Shenzhen metro Line 1, so central Shenzhen is one train away.

2. Lok Ma Chau and Huanggang (落马洲 / 皇岗), open all night

Two crossings share this stretch of border, and the naming confuses everyone.

Lok Ma Chau Spur Line (MTR). Same idea as Lo Wu. Take the East Rail Line to Lok Ma Chau station. The pedestrian crossing runs 6:30 AM to 10:30 PM, and a bridge connects to Shenzhen metro Line 4 and Line 10 at Fumin station.

Huanggang Port (bus and car). This is the one land crossing that stays open all night. It sits about a kilometer from the MTR station, so you reach it by bus or taxi. Frequent cross-border minibuses (locals call them the “yellow buses”) run 24 hours. If you need to cross after midnight, this is your only land option.

• MTR crossing hours: 6:30 AM to 10:30 PM
• Huanggang Port hours: 24 hours
• Good for: late arrivals, anyone who needs flexibility
• Tip: the Huanggang bus terminal on the Hong Kong side runs direct buses to Shenzhen destinations, including the airport. Cheaper than a taxi, and it runs all night.

3. Shenzhen Bay Port (深圳湾口岸), both borders in one building

Opened in 2007, Shenzhen Bay is the most modern land crossing. It is the only one with co-located vehicle clearance, meaning you clear both Hong Kong and mainland formalities in the same building. You stop once.

• Hours: 6:30 AM to midnight daily
• Getting there: cross-border buses from Tsim Sha Tsui, Mong Kok, or the airport; taxi; private car
• Good for: drivers, airport transfers, western Shenzhen (Nanshan, Qianhai)

The immigration halls feel the roomiest of any crossing, and in traveler reports its queues read as more orderly than Lo Wu or Lok Ma Chau. On the mainland side you land in Nanshan, Shenzhen’s tech district, with quick access to the Shenzhen Bay Super Headquarters Base and the shopping around Houhai.

For drivers this is the pick. The co-located setup saves a second stop.

4. Heung Yuen Wai / Liantang (香园围 / 莲塘), new in 2023

Cargo trucks have run through this crossing since August 2020, and it opened to passengers on 6 February 2023, when Hong Kong and the mainland fully resumed normal travel. By traveler accounts it has since become a popular way into Shenzhen’s east.

• Hours: 7:00 AM to 10:00 PM daily
• Getting there: Citybus B7 from Sheung Shui on the Hong Kong side; a car park with booking on site
• Mainland port: Liantang Port
• Metro: Line 8 to Liantang Checkpoint Station on the Shenzhen side
• Good for: Yantian, Dameisha, the beaches and hills of east Shenzhen

The 7 AM to 10 PM window is shorter than the other big crossings, and there has been public pressure to extend it. As of 2026-07 the hours have not changed. Check operating hours at the HK Immigration Department control points page and access routes at the HK Transport Department page, both as of 2026-07.

5. Hong Kong-Zhuhai-Macao Bridge (HZMB): the long way west

The HZMB is a 55-kilometer bridge-and-tunnel system that links Hong Kong to Zhuhai and Macao. It opened in 2018 and added a whole new western route. The crossing itself never closes.

• Hours: 24 hours
• Getting there: the shuttle bus (“Golden Bus”), private cars with permits, cross-boundary coaches
• Mainland port: Zhuhai Port (toward Gongbei)
• Good for: Zhuhai, Macao, western Guangdong

The shuttle runs around the clock, with buses about every 5 minutes at peak and every 15 to 30 minutes overnight. The daytime fare is HK$65 (06:00 to 23:59) and HK$70 from midnight to 5:59 AM. Children under 12 or under 1.2 meters pay HK$33 by day, and under-3s who do not take a seat ride free. Octopus works at the ticket gates. The ride between the Hong Kong and Zhuhai ports takes roughly 40 minutes, plus immigration at both ends. Confirm fares and frequency at the official HZMB shuttle site as of 2026-07.

If Macao is the goal, take the shuttle to the Zhuhai port and cross into Macao through the adjacent gate. Macao runs its own immigration, so you clear mainland exit and Macao entry separately. That Zhuhai–Macao hop is also the closing leg of the Greater Bay Area visa-free loop, a seven-day circuit that chains Hong Kong, Shenzhen, Guangzhou, and Macau together on one 240-hour transit window.

6. Man Kam To (文锦渡), mostly for cargo

Man Kam To is a freight crossing first. A passenger service exists, but it is thin.

• Hours: 7:00 AM to 10:00 PM (HK Immigration control points)
• Getting there: cross-border bus or private car
• Good for: almost nobody, unless you are already nearby

Skip it unless you have a specific reason.

7. Sha Tau Kok (沙头角), cargo only for now

Sha Tau Kok sits in the far northeast of the New Territories, near Shenzhen’s Yantian District. Passenger clearance here is suspended until further notice per the Hong Kong Immigration Department; cargo clearance resumed in February 2023, when the two sides restored freight flows.

• Status: passenger clearance suspended; cargo only
• Getting there: private car or limited bus service
• Good for: border-area residents or anyone with freight business around Yantian

The Hong Kong side of Sha Tau Kok village sits inside a closed area that needs a permit. Not a crossing for ordinary tourists.

The ferries

Not land crossings, but worth a look. High-speed ferries run from Hong Kong to Shenzhen Shekou, Shenzhen Fuyong (next to the airport), Zhuhai, Guangzhou, and Macao.

• Hours: roughly 7:00 AM to 9:00 PM, varies by route
• Good for: a direct run to Shenzhen airport (Fuyong), Shekou, or Zhuhai
• Crossing time: 30 minutes to about an hour, depending on destination

Ferries skip the land queues entirely and drop you at your destination without the metro transfer. The cost runs higher than the bridge shuttle. TurboJET and Cotai Water Jet cover the Macao routes and publish fares on their timetable pages; the Shekou service covers Shenzhen. Fares vary by route, cabin class, and sailing time, so price your own trip on the operator’s page before you book. Sailings can be canceled in bad weather or typhoons.

The Express Rail Link (West Kowloon)

This is the high-speed rail link from Hong Kong West Kowloon Station into the mainland network. It opened in 2018, paused during the pandemic, and has fully resumed.

• Hours: about 6:30 AM to 10:30 PM
• Getting there: MTR to West Kowloon Station, then the high-speed train
• Reach: Shenzhen North in about 14 minutes; Guangzhou South in about 47 minutes; onward services to Changsha, Wuhan, Shanghai, and Beijing
• Immigration: co-located at West Kowloon, so you clear both Hong Kong and mainland checks before you board

The co-located clearance is the selling point. Once you are on the train, there are no more border stops. You surface at Shenzhen North with direct access to metro Line 4 and Line 5, and to high-speed connections across the country. Check live fares and times on the MTR High Speed Rail planner as of 2026-07.

If you are going anywhere beyond Shenzhen, this is the fastest door-to-door option from central Kowloon.

For eligible passports, this crossing is now a visa-free door too. West Kowloon joined the 240-hour transit ports on November 5, 2025, so you can ride the train into Shenzhen without a Chinese visa as long as you hold a confirmed onward ticket to a third country or region. If you’re not sure whether your passport and routing qualify you to cross visa-free, our dedicated guide walks through the documents and the desks you’ll face.

How long does each crossing take?

The numbers below are editorial estimates, not official figures. No authority publishes typical queue times, so each row combines published operator travel times with our assumed mid-length immigration queue on a quiet Wednesday midday, starting from Tsim Sha Tsui. Treat them as planning ranges, not predictions.

| Crossing | Immigration | Door-to-door from TST (estimate) | |---|---|---| | Lo Wu | 20–30 min | 45–60 min | | Lok Ma Chau (MTR) | 25–35 min | 50–70 min | | Shenzhen Bay (bus) | 15–25 min | 50–65 min | | HZMB shuttle | 20–30 min | 90–120 min | | Ferry to Shekou | 10–15 min | 50–70 min | | Express Rail | 15–20 min | 40–50 min |

In peak hours, double or triple everything. Lo Wu on a Monday morning can hit 90 minutes for immigration alone.

The Shenzhen metro advantage

Every major land crossing connects to the Shenzhen metro, which is clean, cheap, air-conditioned, and extensive. Once you are through mainland immigration, most of the city is within 30 to 45 minutes by train.

• Lo Wu: Line 1 (Luohu station)
• Lok Ma Chau (Spur Line): Line 4 or Line 10 (Fumin station)
• Shenzhen Bay: Line 2 (Sea World area), then a short bus or taxi hop
• Heung Yuen Wai / Liantang: Line 8 (Liantang Checkpoint station)
• West Kowloon / Shenzhen North: Line 4 or Line 5 (Shenzhen North station)

Payment methods on the Shenzhen Metro keep shifting. The Shenzhen Tong stored-value card works across the metro and most buses, per the Shenzhen city government’s transport guide. Travelers also report paying with Alipay or WeChat Pay at machines or gates, though coverage for foreign-linked accounts is inconsistent. Ticket machines are phasing out cash while staffed counters still take it. Set up a payment method before you arrive, carry some cash as backup, and do not count on a single option working.

Timing and the small stuff that matters

The border is a game of timing. Here is when to move and when to wait.

Avoid these windows:

• Monday 7:30 to 9:30 AM: Shenzhen residents crossing into Hong Kong for work
• Friday 5:00 to 8:00 PM: Hong Kong residents heading to Shenzhen for the weekend
• Saturday 10:00 AM to 2:00 PM: shoppers and day-trippers
• Chinese public holidays (Golden Week, Lunar New Year): every crossing gets crushed. Avoid if you can.

Best windows:

• Tuesday to Thursday, 10:00 AM to 3:00 PM
• Saturday or Sunday before 9:00 AM
• After 9:00 PM on the 24-hour Huanggang crossing

The small stuff:

• Carry a pen. You may need to fill out a paper arrival card on the mainland side.
• Get your visa documents and QR codes ready before you reach the counter, not while you stand in line.
• Sort connectivity ahead of time. A Hong Kong SIM will not work on the mainland side without roaming. You may find carrier kiosks or vending near the bigger ports, but their presence changes, so do not rely on buying a SIM at the border. Install an eSIM or a roaming plan before you travel.
• The currency changes. Hong Kong uses HKD; the mainland uses RMB. Money changers at the border give poor rates. ATMs on either side are better.

FAQ

The bottom line

Sort your visa first, because the single-entry trap catches more travelers than any queue. Then pick the crossing by destination, not by what looks closest on a map. Lo Wu or the Express Rail Link for central Shenzhen and points beyond. Shenzhen Bay or the HZMB for the west. Heung Yuen Wai for the east. Huanggang when it is 2 AM and you just need to get across. Give yourself 30 spare minutes whatever you choose, because the border has a habit of using whatever time you hand it.
