The figures come from the stock held on each site, not from an operator’s advertising.
Algarve, Portugal
101 offers · from €11.45 · median €42 · 71,632 reviews
The marina sits about fifteen boat minutes from Benagil Cave — no other large harbour on this coast is closer. It also has the highest density of operators in the Algarve, which keeps transfers short and prices under competition.

Western Algarve (Barlavento), Portugal
119 offers · from €6 · median €48.80 · 65,552 reviews
Ten boat minutes out from the marina stand the pinnacles and grottoes of Ponta da Piedade — and there is no two-minute rule here as at Benagil, the small boats really do go inside. This is also where the largest kayak offering of the three Algarve destinations sits.

Central Algarve, Portugal
134 offers · from €14 · median €45 · 98,734 reviews
More boats leave here per day than anywhere else on this coast, and if the morning departure is cancelled there is an afternoon one — elsewhere there is one tomorrow. It also has the largest offering on land of the Algarve destinations, water parks included.

Madeira, Portugal
361 offers · from €9 · median €60 · 134,016 reviews
An island rather than a stretch of coast: levada walks, jeep tours into the central mountains, and whale and dolphin trips. Dolphins live off Madeira all year and several whale species pass through — the odds are good, but nothing is guaranteed.

Canary Islands, Spain
307 offers · from €6 · median €66.40 · 222,902 reviews
The only island with a 3,000-metre peak: Teide rises above a coast where whales and dolphins stay all year.

Canary Islands, Spain
247 offers · from €10 · median €69 · 73,568 reviews
An island like a small continent: dunes in the south, pine forest in the middle, a real city in the north.

Canary Islands, Spain

A volcanic landscape that looks like another planet — and you may drive a buggy right through it on the road.

Canary Islands, Spain
183 offers · from €12.50 · median €70 · 56,125 reviews
The longest beaches of the archipelago and the most reliable wind — off the northern tip lies the uninhabited island of Lobos.

Eastern Algarve, Portugal

A town behind a lagoon: the beach sits on an island, and the only way there is the ferry.

Algarve, Portugal
63 offers · from €6 · median €50 · 17,472 reviews
A built marina rather than a grown harbour: the longest Benagil runs on this coast start here.

Western Algarve, Portugal

The end of Europe: at Cabo de São Vicente the Algarve as you know it stops and the Atlantic coast begins.

Red Sea, Egypt
224 offers · from €7.57 · median €35.80 · 123,976 reviews
A reef starts a few boat minutes off the coast — which is why nearly everything here happens on the water.

Upper Egypt, Egypt
85 offers · from €10.32 · median €68.77 · 14,826 reviews
The largest open-air museum in the world: temples on the east bank, royal tombs on the west, the Nile in between.

A medina you explore on foot, and a stone desert that begins an hour away.

Western Cape, South Africa

A city that starts in the evening — and the closest gateway to the Grand Canyon.

Andaman Sea, Thailand
563 offers · from €9.40 · median €60.13 · 152,662 reviews
The departure port for the islands of the Andaman Sea: Phi Phi, Coral, Racha, the Khai islands. Phi Phi day trips start at just over €31, and what separates them is the route, not the price.

Northern Portugal, Portugal
429 offers · from €5 · median €54.60 · 258,677 reviews
Port wine and the Douro valley in one place. The lodges stand across the river in Vila Nova de Gaia, and two of them fit comfortably into an afternoon. The valley you reach by van, by boat, by train — or on your own for just over €12 on the line to Pinhão.

Lazio, Italy
632 offers · from €3.20 · median €53.55 · 938,861 reviews
Colosseum, Forum, Vatican — the three names almost everyone comes for. The sheer number of listings is the problem here: what separates two guided tours sits in the small print, not the title. The arena floor, for one, costs €6 above the base ticket, for twenty minutes.

Singapore, Southeast Asia
306 offers · from €2.73 · median €57.07 · 52,445 reviews
A city that looks best after dark: light shows at Gardens by the Bay, observation decks, trips on the river. Changi to Marina Bay is about fifty minutes on the train and the last trains go around midnight — that arithmetic decides the evening more than any choice of attraction.

New South Wales, Australia
351 offers · from €1.24 · median €86.54 · 83,620 reviews
The harbour is the centre of it: cruises from Circular Quay run from half an hour to three, €22 to €74 — and the public ferry crosses the same water for an Opal day cap of A$9.65. Alongside that, the Opera House costs an hour and the Blue Mountains cost a day.

Lisbon Region, Portugal
615 offers · from €1.50 · median €50 · 347,660 reviews
The Tagus is what people book here first: 122 boat offers from €15, and nearly all of them leave from the same six hundred metres of waterfront. The difference is not the water — it is duration, purpose and who is allowed on board.

Kansai, Japan
706 offers · from €1.12 · median €58.83 · 113,829 reviews
Culture is the substance here, not the backdrop: ninety tea ceremony offers alone, from €2.79 to over €100, and the ratings do not follow the price. The bamboo path in Arashiyama costs nothing and takes twelve minutes; everything beside it is a separate ticket with its own calendar.

Mascarenes, Mauritius
347 offers · from €10 · median €90 · 41,173 reviews
What you may do on the water here sits in regulations, not in an operator’s small print: dolphin trips may only be sold from 6am to noon, and three swimmers may be in the water at a time — the crew’s life-saver among them. Blue Bay is a 353-hectare marine park with its own zones, where boats are held to three knots.
