The coast appears bare and mineral: ochre mountains falling toward the Red Sea, a light coastal strip, a few cranes. Duba—or Dhiba—is the first Saudi port that ships from the Suez Canal meet, and one of the kingdom's newest entry gates for cruise passengers. Here, there is no old city to wander on disembarkation: the port-call happens as a day of expedition inland, where north-western Arabia reveals landscapes few travellers have yet seen.

A Small Red Sea City

Duba has about 22,000 residents, an active commercial port and a ferry linking Saudi Arabia to Egypt. The city itself lives by fishing and transit: its corniche, its fish market and its mosques compose a daily, unadorned setting; the Red Sea here hides coral reefs that have remained remarkably intact, and swimming or snorkelling sorties figure sometimes in the programme depending on the cruise line, where visitors remain a novelty. It is precisely this that strikes: the kingdom's tourism opening is recent, and curiosity plays in both directions. A smile and a few words of English often suffice to spark conversation over a cardamom coffee.

Tabuk, the Capital of the North

Most excursions head to Tabuk, about 180 kilometres by road. The provincial capital preserves a 16th-century fort, a historic stop for pilgrim caravans en route to Medina and Mecca, as well as a restored station of the legendary Hejaz Railway, whose locomotives echo the epic—and Lawrence of Arabia's passage through the region. The journey itself has the air of an expedition: plains of basalt, clear dunes and jagged massifs stream past the windows.

Wadi Disah, the Canyon of Palms

The longest days lead by all-terrain vehicle to Wadi Disah, one of Arabia's finest canyons. Between walls of sandstone sculpted by erosion, a spring feeds a ribbon of palms and reeds—an unexpected linear oasis amid stone. You walk there in the shadow of the cliffs, you share tea, dates and Bedouin hospitality on the carpets of an encampment. The excursion takes several hours of driving; it addresses travellers who want to see Arabia of raw landscapes, not that of shopping centres.

NEOM, the Future Under Construction

Duba also sits at the gates of NEOM, the futuristic region the kingdom is raising from the desert by the Red Sea. The site, colossal, remains largely closed to the public, but its presence explains the new roads and activity spreading along the coast; travellers for now content themselves with glimpsing its construction sites as the ship navigates. The port-call thus offers a rare snapshot: a country in full metamorphosis, observed from one of its quietest margins.

What to Know Before Disembarking

• Disembarkation happens at a commercial port; organised excursions constitute the simplest way to venture out.
• Allow for long distances: Tabuk about 2 hours by road, Wadi Disah further.
• Clothing covering shoulders and knees recommended; water and a hat are essential.
• The currency is the riyal; cards work well in town, less in the desert.

As evening comes, when the ship returns to sea facing mountains ablaze with sunset, the port-call leaves the feeling of having opened a door the world is only now beginning to push. Few itineraries still offer that: a shore whose travel guides are being written at this very moment. The canyons of north-western Saudi Arabia, meanwhile, have not finished speaking.
