Cities in the ocean are cities built on islands or reclaimed land, surrounded by sea on every side: Malé in the Maldives, the island city-state of Singapore, Hong Kong Island, Zanzibar's Stone Town and Valletta on Malta. They are worth visiting for the same reason they are hard to build: every street, harbour and skyline is shaped by limited land and open water. This guide covers five ocean cities, what makes each one unusual, how to reach it and how long to stay.
The list focuses on cities themselves. For resort islands, see our Maldives honeymoon guide and Mauritius in the Indian Ocean; for a lagoon city on stilts, see the best attractions in Venice.

Which cities are surrounded by ocean?
Strictly, any city on a small island qualifies, but five stand out for travellers because the sea defines daily life: you arrive by boat or across a bridge, land is scarce, and the waterfront is the city centre. They also cover very different regions and budgets, from Southeast Asian megacities to a small Mediterranean capital.
It helps to separate three kinds of place that often get mixed up. An island city covers most or all of an island, so water surrounds it on every side; Malé and Singapore are the clearest examples. A peninsula city is joined to land on one side but feels like an island, as in Valletta. And some coastal cities began as islands and were joined together by land reclamation. Mumbai is the best-known case: it grew on a group of seven islands that were linked by causeways and reclaimed land, beginning with the Hornby Vellard dam in the 1780s and continuing through the 19th century, so today it reads as a peninsula city.
Other places travellers sometimes add to the list include Venice, which stands on islands in a lagoon away from the open sea, and Lagos Island in Nigeria, the historic core of a much larger mainland metropolis. They are covered elsewhere or fall outside this guide's focus, which is on cities where the sea is the boundary of the whole city, and where getting in usually means a boat, a causeway or a flight.
Five ocean cities worth the trip
Malé, Maldives
Almost the whole of its island is taken up by Malé, which is why it ranks among the most densely populated cities in the world. Tall, narrow apartment blocks fill every plot, scooters crowd the lanes, and the harbour fronts are lined with ferries and supply boats heading out to the atolls.
Most visitors only pass through on the way to a resort, but half a day in Malé is worthwhile: the fish market at dawn, the waterfront and the old mosques give a sense of Maldivian life that resorts do not. Next door, Hulhumalé is an artificial island that has been reclaimed from the lagoon since 1997 to ease crowding in the capital, and it now houses tens of thousands of people. The airport island sits between the two, linked by a bridge.
Half a day to a full day is enough. Guesthouses in Hulhumalé, near the airport, make the easiest base, and you get around on foot, by taxi or on local ferries for a real look at Maldivian city life.
Singapore
Country, city and island at once, Singapore is separated from Malaysia by a narrow strait crossed by causeway and bridge. Land reclamation has pushed its shoreline out over decades; the Marina Bay area, now the city's showpiece waterfront, stands largely on reclaimed land.
It is the easiest ocean city on this list to visit: one of the world's busiest airports, excellent public transport and clear signage in English. Spend the days on hawker centres, the old shophouse districts and the gardens, and take a ferry or the cable car out to the smaller islands to see how much of the country is sea.
Two to four days suits most first-time visitors to Asia and anyone who travels to eat. Stay around Marina Bay, Chinatown or Bugis and use the MRT and buses.
Hong Kong Island
Hong Kong Island rises steeply from Victoria Harbour, so the city stacks upward: towers climb the slopes, and outdoor escalators and the Peak Tram carry people uphill. Across the water, Kowloon faces it on the mainland side, and the Star Ferry crossing between the two is one of the cheapest great views in Asia.
Beyond the financial district, the south side of the island has beaches and fishing-village harbours such as Aberdeen, and more than 200 outlying islands lie offshore. For shopping, our guide to the markets of Hong Kong covers the street markets in detail.
Plan three to four days, based in Central, Wan Chai or Tsim Sha Tsui across the harbour. The MTR, the trams and the Star Ferry cover everything, and the payoff is the skyline and the pace of the city.
Stone Town, Zanzibar, Tanzania
On Unguja island, Stone Town is the old quarter of Zanzibar City. UNESCO inscribed it as a World Heritage Site in 2000 as an outstanding example of a Swahili coastal trading town, which flourished in the 19th century as the capital of the Zanzibar Sultanate and a centre of the spice trade.
The town is a maze of narrow lanes, carved wooden doors, mosques and coral-stone houses. Evenings at the Forodhani waterfront bring food stalls and sunset dhow trips. Its history includes the East African slave trade, and the memorial at the former slave market site is an important, sobering visit. Most travellers combine Stone Town with the beaches on the island's north and east coasts.
Two days covers the town, with nights in one of the restored townhouse hotels. Fly to Zanzibar or take the ferry from Dar es Salaam. History and architecture are the draw, and spice tours run from here.
Valletta, Malta
The Knights of St John built Valletta in the 16th century on a narrow peninsula between two deep harbours, and UNESCO listed the whole city as a World Heritage Site in 1980. The city is a tiny capital by EU standards, so the entire grid of honey-coloured streets can be walked in a day.
The views over the Grand Harbour to the Three Cities are the highlight, especially from the Upper Barrakka Gardens. Malta is an island nation, so Valletta works as a base for ferries to Gozo and for swimming spots along the rocky coast.
A day or two is right for anyone interested in architecture and Mediterranean history. Sleep in Valletta itself or in Sliema across the harbour, and get around on foot and by harbour ferry.
Ocean cities compared
Five ocean cities, side by side
| City | Ocean or sea | Main hub | Days | Character |
|---|---|---|---|---|
| Malé | Indian Ocean | Velana International (airport island) | 0.5 to 1 | Dense local capital |
| Singapore | Strait of Singapore | Changi | 2 to 4 | Modern city-state |
| Hong Kong Island | South China Sea | Hong Kong International | 3 to 4 | Vertical skyline city |
| Stone Town | Indian Ocean | Zanzibar airport | 2 | Swahili heritage port |
| Valletta | Mediterranean | Malta International | 1 to 2 | Fortified historic capital |
The table shows a clear split. Singapore and Hong Kong Island are full cities that justify several days on their own and work as long-haul stopovers, with fast public transport from the airport and plenty of hotels at every price. Malé, Stone Town and Valletta are compact and walkable, and most travellers combine them with something else: resort islands in the Maldives, the beaches of Zanzibar's north and east coasts, or Gozo and Malta's coast.
Budget follows the same pattern. Singapore and Hong Kong hotels are expensive per square metre, and Malé's guesthouse rooms are simple but far cheaper than resort stays on the atolls. Stone Town and Valletta both offer small heritage hotels in restored buildings, often with steep stairs and no lift, so check access before booking if mobility is a concern. For two ocean cities on one trip, Singapore and Malé are linked by direct flights, and Valletta pairs naturally with a Mediterranean itinerary through Italy.
How to plan a trip to an ocean city
- Use the hub. Singapore and Hong Kong are major airline hubs, so they pair well as stopovers on long-haul trips. Compare routes on our flight search.
- Watch the weather. Tropical ocean cities have monsoon or typhoon seasons. Check the season for your dates before you book.
- Plan for ferries. Ferry timetables shift with weather and season, especially in the Maldives and Zanzibar. Leave buffer time before flights.
- Book central. Land is scarce, so hotels are small and central areas fill early. Book ahead for holidays.
- Dress codes. Malé and Stone Town are conservative Muslim cities. Cover shoulders and knees in town.
- Check entry rules. Visa rules depend on your passport. Use each country's official portal or our visa page before you travel.
Seasons differ sharply between the five. Singapore is hot and humid all year, with the wettest months usually from November to January. Hong Kong's typhoon season runs from roughly May to November, and a high typhoon signal can halt ferries, flights and the Star Ferry for a day; October to December is generally the most comfortable period. In Zanzibar, the long rains fall from about March to May, and the dry months from June to October suit beach add-ons. The Maldives runs on a different rhythm: the drier north-east monsoon lasts from about December to April, and the wetter south-west monsoon from May to October. Valletta is pleasant in spring and autumn, crowded and hot in July and August, and quiet but mild in winter, when some ferry and boat-trip timetables are reduced.
Ramadan also changes daily life in Malé and Stone Town: many cafés close in daylight hours and evening food markets come alive after sunset, so check the dates if you plan to visit either city that month.
