Southeast Asia Cruises: River or Sea?
People often picture just one type of Southeast Asia cruise, but in reality 2 completely different products coexist. One is a river cruise sailing along the Mekong, and the other is an ocean cruise visiting several countries from a major port such as Singapore. The ships, cabin layouts, pace of travel, and fare levels are all quite different, so it is easy to feel lost during booking unless you first decide what you want.
As of September 30, 2026, CruiseMap lists 759 Southeast Asia cruise departures, 19 ships, and 7 cruise lines. Many are small ships sailing rivers, while the rest are large ocean-going cruise ships. This article compares the 2 categories by departure port, featured routes, and fare levels, and explains which type suits different travelers.
Why Should You Consider Them Separately?
Mekong River cruises sail on a river, so their ships are small and passenger capacity is limited. Ocean cruises sail on seas such as the South China Sea or Andaman Sea, so they use larger ships and distances between ports are much longer. These differences directly shape the travel experience. On a river, you pass villages and temples and see local life up close; at sea, it is more like a resort trip where you travel while enjoying the ship’s facilities.
Mekong River Cruises: Indochina from the River
Mekong River cruises account for the largest share of Southeast Asia cruises. According to CruiseMap, Pandaw has 297 sailings, and small cruise lines specializing in river routes make up a substantial portion of the total. The main departure ports are Ho Chi Minh City (157 sailings), Ben Tre (105), Siem Reap (95), and Phnom Penh (34). The main cruising area is the Mekong and its tributaries connecting southern Vietnam and Cambodia.
Featured Ships and Their Characteristics
RV Tonle Pandaw, operated by Pandaw, has the most sailings among Pandaw ships, with 104, and a median lowest fare of $1,422 per person (USD per person; checked on 2026-09-30). RV Mekong Pandaw has 39 sailings and a median lowest fare of $4,742 per person, while RV Bassac Pandaw is at the same fare of $4,742. RV Angkor Pandaw has 32 sailings and a fare of $5,718, and RV Laos Pandaw has 27 sailings and a fare of $5,816. Fares vary considerably even within the same cruise line, depending on the ship and route.
Emerald Harmony, operated by Emerald Cruises, is listed with 288 sailings, but products that add a land itinerary on the same departure date are recorded separately, making a direct comparison of sailing counts with Pandaw ships difficult. Its median lowest fare per person is $4,798. The same cruise line's Emerald Xara is an ocean-going yacht, not a river ship; it has 36 sailings and a median lowest fare per person of $9,859. River and ocean cruises are different kinds of products, so their fares are difficult to compare on the same basis.
Starting with a Short Itinerary
If you are new to Mekong River cruises, one option is to begin with a short itinerary. Saigon to Phnom Penh is a 2-night itinerary. RV Tonle Pandaw departs from Ben Tre, passes Chau Doc, crosses the Cambodian border by ship, and arrives in Phnom Penh. It has 102 departures on the same route and a lowest fare per person starting at $1,175. Crossing a national border by ship is a unique attraction of a river cruise that is hard to experience by land.
If You Want a Longer Trip The appeal of the Mekong and Siem Reap is an itinerary worth considering. It is 7 nights, and Emerald Harmony departs Ho Chi Minh City, calls at Ben Tre, Sa Dec, Gieng Island, and Tan Chau, then travels via Phnom Penh and Rokar Kong before arriving in Siem Reap. It has 41 departures and a lowest fare per person starting at $3,216. Pandaw’s Classic Mekong itinerary is also 7 nights, but it departs Ho Chi Minh City and has different port calls, including Tonle Sap, Oudong, and Pham Chikang. It has 17 departures and fares start at $4,311 per person.
Ocean Cruises from Singapore: Connecting Countries by Sea
Ocean cruises offer a completely different approach from river cruises. Singapore is a key gateway for ocean cruises in Southeast Asia, with 45 departures listed there by CruiseMap. Although there are fewer departures than for river cruises, large cruise lines use this port as a hub for routes around several Southeast Asian countries.
Cruise Lines and Ships
In the ocean cruise category, Regent Seven Seas Cruises has the most sailings, with 84, followed by The Ritz-Carlton Yacht Collection with 25, Norwegian Cruise Line with 14, Atlas Ocean Voyages with 11, and MSC Cruises with 4.
The featured ship Seven Seas Explorer has 35 sailings and a median lowest fare per person of $16,049, a fare level even higher than the top-tier river cruise ships. This reflects its all-suite accommodation, dining, and product structure designed for longer sailing distances. Ocean cruises generally call at major cities or ports in different countries every few days. Spending much more time on board than on river cruises also contributes to the difference in fares.
Who Should Choose an Ocean Cruise?
Travelers who want to make full use of onboard facilities such as pools, theaters, and multiple restaurants, or prefer to visit a different country’s port every 1 or 2 days, may be better suited to an ocean cruise. By contrast, if you want to see villages and temples up close along a narrow river, a river cruise better matches that goal.
Fares and Nights: Southeast Asia Cruises in Numbers
Across all 759 Southeast Asia cruise departures, the most common length is 7 nights and the median is also 7 nights. Half of all cruises are between 7 and 10 nights, making an itinerary around a week a standard option. Among the 719 sailings with fare data, the lowest fare per person is $1,422 at the 10th percentile and $5,217 at the median, with a median rate of $677 per night.
Keep in mind that this is the lowest starting fare per person. Prices rise for higher cabin categories or peak-season departures. Airfare, onboard gratuities, and port excursions are also generally not included. Since inclusions and extras vary by cruise line and fare type, be sure to check before booking.
When Departures Are Concentrated
Southeast Asia cruises tend to have more departures during the dry season. CruiseMap data shows January 2028: 76 sailings as the busiest month, followed by March 2028: 63 sailings, February 2028: 58 sailings, November 2027: 51 sailings, October 2027: 50 sailings in that order. Since there are more options during these periods, keep in mind that competition for cabins on popular cruises may also increase.
Compare Featured Itineraries at a Glance
Mekong River cruises offer different options depending on the number of nights and route. The table below lists 3 featured itineraries registered on CruiseMap.
| Itinerary | Nights | Ship | Main ports of call | Lowest fare per person (USD) |
|---|---|---|---|---|
| Saigon to Phnom Penh | 2 nights | RV Tonle Pandaw | Bến Tre → Châu Đốc → Cambodian border → Phnom Penh | From $1,175 |
| The appeal of the Mekong and Siem Reap | 7 nights | Emerald Harmony | Ho Chi Minh City → Ben Tre → Sa Dec → Gieng Island → Tan Chau → Phnom Penh → Rokar Kong → Siem Reap | From $3,216 |
| Classic Mekong | 7 nights | RV Mekong Pandaw | Ho Chi Minh City → Ben Tre → Chau Doc → Phnom Penh → Tonle Sap → Oudong → Pham Chikang → Siem Reap | From $4,311 |
If you only want the short experience of crossing a border, a 2-night itinerary is suitable; if you want to explore more of Indochina in depth, choose a 7-night itinerary. Even with the same 7-night duration, ships and ports of call vary, so check the route table carefully to see which villages are included.
What to Check Before Choosing
Cabins and Accessibility
River cruise ships have fewer cabins and fewer decks than large ocean cruise ships. Note that balconies and river views work differently from the oceanview concept on ocean cruises. Large ocean cruises offer a wider range of cabin categories, including balconies, suites, and inside cabins, and fare differences are correspondingly larger.
Check Inclusions
Inclusions vary greatly among Southeast Asia cruise lines. Some river cruise products include port excursions in the fare, while others charge separately. Cancellation and refund terms and payment schedules also vary by cruise line and fare type, so be sure to check the terms before booking.
Choose According to Your Travel Goals
If you want to see local life up close along the river, consider river cruises from Pandaw or Emerald Cruises. If you want to visit several countries and enjoy onboard facilities, consider ocean cruise lines such as Regent Seven Seas Cruises or Norwegian Cruise Line.
Frequently Asked Questions
Where should I start: a Mekong River cruise or a Singapore cruise?
If you are new to cruising and want to try a short itinerary, you can start with a short river cruise such as the 2-night Saigon–Phnom Penh route. Conversely, if you want onboard amenities and visits to several countries, an ocean cruise departing from Singapore is a good fit.
What is a standard itinerary length for a Southeast Asia cruise?
According to CruiseMap, the most common length is 7 nights, and half of all cruises are between 7 and 10 nights. If this is your first cruise, around 7 nights is a reasonable benchmark.
Does the lowest fare per person include airfare?
Generally, no. The price shown is the lowest fare per person, and airfare, onboard gratuities, and port excursions are often extra. Exact inclusions vary by cruise line and fare type, so check during booking.
How large are Mekong River cruise ships?
They are much smaller than large ocean-going cruise ships. They need a shallow draft to navigate the river and have limited cabin capacity. Even a ship such as RV Tonle Pandaw, which operates 104 sailings, is considered small compared with an ocean cruise ship.
When are there the most departure options?
According to CruiseMap data, January 2028 has the most, with 76 sailings, followed by March and February 2028. These months coincide with the dry season, so there are many options, but competition for cabins on popular cruises can also increase.
