Hong Kong's public transportation system is recognized as one of the most efficient in the world, with MTR subway on-time rates reaching 99.9%, covering Hong Kong Island, Kowloon, the New Territories, and the airport. This guide covers Octopus card purchase and top-up, MTR nine-line fares, Airport Express discounts, bus, minibus, and tram fares, and the red/green/ blue taxi distinctions, allowing first-time visitors to Hong Kong, foreign residents, and business travelers to quickly master the full picture of Hong Kong transportation.
Hong Kong Transportation Overview: Why Hong Kong's Public Transportation is the World's Most Efficient?
Hong Kong's public transportation carries over 12 million passengers daily, with a public transportation modal share of 89%, ranking among the highest globally. MTR currently operates 9 urban lines and 1 Airport Express line, totaling over 230 km in length, with on-time rates maintained above 99.9% for consecutive years, and train intervals of just 2 minutes during peak hours. The bus network covers over 700 routes, together with minibuses, trams, and taxis, forming an extremely dense transportation network.
The efficiency of Hong Kong's public transportation comes from a well-planned integrated system—the Octopus card supports MTR, buses, trams, ferries, and almost all modes of transportation, allowing one card to travel without needing to buy separate tickets. All three major areas—Hong Kong Island, Kowloon, and the New Territories—are connected by well-developed railway lines, and the Airport Express provides direct access to the city center in just 35 minutes. Travelers only need to familiarize themselves with the Octopus card and MTR lines to efficiently navigate the entire territory.
Octopus Card: Hong Kong's Essential Transportation Payment Tool
The Octopus is Hong Kong's most popular electronic payment card, usable on MTR, buses, trams, ferries, minibuses, and taxis, as well as at convenience stores, supermarkets, and vending machines. Travelers can purchase an Octopus at any MTR customer service center—adult cards require a HKD50 deposit (refundable), with each top-up starting from HKD100 and a maximum stored value of HKD1000.
When purchasing an Octopus, travelers can choose between a rental version (HKD50 deposit, refunded upon return with the balance and deposit) or a sold version (price HKD39, non-refundable). Octopus cards are also available at Airport Express stations, Maa control area customer service centers, and some convenience stores. Top-ups can be made at MTR self-service machines, customer service centers, or convenience stores. Octopus cards are valid for 3 years and can be renewed free of charge upon expiration.
Before departing Hong Kong, travelers can return the card at any MTR customer service center—the full balance and deposit will be refunded (rental version only). If the Octopus is damaged or the balance exceeds HKD500, refund processing takes 7 working days. If an Octopus is lost, it can be reported immediately and a new card applied for, but the balance cannot be transferred—travelers should take special note of this.
MTR Subway Guide: 9 Lines Covering the Entire Territory
MTR currently operates 9 urban lines: Island Line, Tsuen Wan Line, Kwun Tong Line, Tseung Kwan O Line, Tung Chung Line, East Rail Line, West Rail Line, Tuen Ma Line, and South Island Line, connecting Hong Kong Island, Kowloon, and the New Territories. Fares are calculated by distance, ranging from HKD4.3 to HKD50, and adult Octopus users receive approximately 5% fare discount per trip.
For example, Mong Kok to Central via the Tsuen Wan Line takes about 15 minutes, with Octopus fare at HKD11.1. Commonly used routes for travelers include: Island Line connecting Central, Causeway Bay, North Point; Tsuen Wan Line connecting Mong Kok, Sham Shui Po, Tsuen Wan; East Rail Line connecting Lo Wu Station (cross-border to Shenzhen) and Lok Ma Chau Station. A single trip from Lo Wu Station to Hung Hom Station costs HKD57.5 on Octopus, a popular route for cross-border travelers.
Travelers can purchase the MTR Day Pass (adult HKD65 for unlimited rides), applicable to all MTR lines (except Airport Express, Lo Wu Station, and Racecourse Station), available at any MTR station and valid for unlimited rides on the day of activation. For monthly passes, the Tourist Day Pass is priced at HKD65; the Tourist Monthly Pass provides 30 days of unlimited rides, suitable for business travelers who need to move between districts frequently.
Airport Express: Hong Kong International Airport ←→ City Center Fastest Option
The Airport Express connects Hong Kong International Airport with the city center, with stations at AsiaWorld-Expo, Airport, Tsing Yi, Kowloon, and Hong Kong (Central), taking only 35 minutes from the Airport to Hong Kong Station (Central). Standard single fare is HKD115, Octopus fare is HKD105 (valid until March 2026), round-trip fare is HKD205 for standard and HKD185 for Octopus.

Travelers can purchase the Airport Express Travel Pass at Airport Express stations, which includes a single or round-trip Airport Express journey plus 3 days of unlimited MTR rides, priced from HKD350 to HKD450 for adults, depending on single or round-trip. This package is suitable for travelers staying in Hong Kong for 3 or more days who need to ride MTR frequently—better value than buying tickets separately.
Bus/Minibus/Tram: The Culture of Hong Kong's Ground Transportation
Hong Kong's bus network is operated by KMB, NWFB, Citybus, and Long Win Bus, covering areas not served by MTR. Bus fares start from HKD4.2, with zone-based fares being more complex—travelers can simply tap their Octopus card when boarding, noting the fare displayed on the screen.
Minibuses are divided into red minibuses (operating non-fixed routes, with fares quoted by the driver) and green minibuses (fixed routes and fares, set by the Transport Department). Red minibuses mainly operate in the New Territories and some areas of Hong Kong Island, with no fixed schedule—passengers can flag them down along the route; green minibuses have fixed stops, with fares ranging from HKD4.2 to HKD30.
The Ding Ding tram is the world's only remaining double-decker tram system, running along the north side of Hong Kong Island from Kennedy Town to Shau Kei Wan, and from Happy Valley to Shek Tong Tsui. Adult single fare is only HKD2.3, with children and seniors at half price. Travelers can board at any tram stop, tapping their Octopus or inserting coins at the rear gate—the driver does not provide change. The most characteristic route is the eastward Island Line (from Kennedy Town to Shau Kei Wan), offering views of Hong Kong Island's north-side cityscape—the best way to experience old Hong Kong culture.
Taxis: Hong Kong's Red/Green/Blue Taxi Zone Regulations
Hong Kong taxis come in three colors: red taxis (urban taxis) can operate in most areas of Hong Kong, starting meter fare is HKD29, then HKD1.9 per 200 meters after the first 2 km, and HKD2.9 per minute while waiting; green taxis (New Territories taxis) mainly operate in the northern New Territories and parts of Lantau, starting meter fare is HKD24.5; blue taxis (Lantau taxis) are restricted to Lantau Island and the Chek Lap Kok airport area, starting meter fare is HKD22.
Travelers should note taxi surcharges: tunnel fees (Cross-Harbour Tunnel HKD25, Eastern Harbour Tunnel HKD30, Western Harbour Tunnel HKD50), luggage fees (HKD6 per item), and animal or pet surcharges (HKD5 per animal). Between midnight and 6 AM, all taxis add a 30% surcharge. Travelers heading to the airport should take red taxis or pre-book airport taxi services.
Travelers can use Uber or the HKTaxi app to book taxis—HKTaxi supports direct booking of red taxis, while Uber offers multiple vehicle model options. Most Hong Kong taxi drivers have limited English ability, so travelers are advised to prepare the destination address in Chinese or a screenshot of the location. Taxi fare from Lo Wu border crossing to the city center is approximately HKD300-400—travelers may find cross-border buses or the East Rail Line more cost-effective.
