The Origins of the Benagil & Marinha Tour: A Personal Story from 2012

This is a subtitle for your new post

How a family holiday shaped our most popular tour.

This itinerary isn't a product of market research; it’s a personal memory.

It started in the summer of 2012, during a family holiday in Carvoeiro. Watching my daughter Inês, then 12 years old, happily exploring the tunnels and natural windows of Boneca and Algar Seco , I realized how magical these hidden spots were compared to the crowded centers.

I also made a point of taking my family to Praia da Marinha , a beach of unmatched beauty that they hadn't seen yet. While Carvoeiro was bustling with people, Marinha offered a breathtaking escape where we could truly relax. It became our sanctuary.

The pieces were there—the beauty of the cliffs, the joy of exploration—but the puzzle finally came together in my mind two years later when an American journalist asked me to guide a couple specifically to the Benagil Sea Cave .

That was the moment everything clicked. I realized that by connecting the stunning Seven Hanging Valleys trail, the peace of Marinha, the rock formations in Carvoeiro, and the boat access to Benagil, I could create the perfect day in the Algarve.

Why We Refuse to Rush

Today, many companies offer a 'Lisbon to Algarve' tour. But at Duca, we keep it original .

I personally designed this day based on what I wanted for my own family:

Time to explore the tunnels at Boneca.
Time to breathe the sea air at Marinha.
A boat to explore several oceanic caves, including Benagil
Flexibility in the afternoon to visit Lagos or Albufeira , or simply enjoy a scenic coastal drive.

We refuse to rush because we believe this journey should be savored, not raced. This is the Duca difference: being the original, and keeping it original.

Sintra: The Origin of the Name

Part I

I was born and raised in Sintra. I have walked its forests, climbed its hills, and guided hundreds of visitors through its palaces and hidden paths. And yet, one question keeps coming back — from curious travellers, from students, from people who simply stop and look up at the mountain and ask: where does the name Sintra actually come from?

It is a fair question. And the honest answer is: nobody knows for certain. But the journey through the possibilities is, in itself, a beautiful piece of Portuguese history.

A Name Older Than Portugal Itself

Sintra is older than the country that surrounds it. Long before Portugal existed as a nation, long before the Moors built their castle on the ridge, long before the Romans marched through the Iberian Peninsula — there were people here. Celtic people, living in the shadow of this granite mountain, looking up at the same sky we look at today.

There is a theory, passed down through generations rather than proven in academic papers, that the Celts named this place after Cynthia — one of the names given to the moon goddess in ancient mythology. The mountain, they say, was a place of lunar worship. A sacred place. A place where the boundary between the earth and something greater felt thinner than usual.

I have always found this theory compelling — not because of the evidence, which is fragile, but because of the feeling. Anyone who has stood on the Sintra hills at night, with the Atlantic mist rolling in and the stars appearing one by one above the pines, will understand why someone might dedicate this place to the moon.

The Romans and the Mount of the Moon

When the Romans arrived, they did something remarkable — they kept the lunar association. They called this place Mons Lunae. The Mount of the Moon.

This is significant. The Romans were not a people known for sentimentality. They renamed places, imposed their language, and built roads over everything that came before. But here, they looked at this mountain and chose to honour what they found — a place already associated with the moon, already considered sacred.

Mons Lunae appears in Roman texts and cartography. It is one of the earliest documented references to this place we now call Sintra. And it tells us something important: that whatever the Celts felt here, the Romans felt it too.

The Moorish Chapter

The Moors arrived in the 8th century and occupied the Sintra region for over four hundred years. Their influence on Portugal — in architecture, in agriculture, in language — is profound and often underestimated.

The Arabic word most often linked to the name Sintra is Xentra or Zintira. Scholars debate its exact meaning, but many connect it once again to the moon. Others suggest it refers to the rocky, rugged nature of the terrain.

What is undeniable is that the Moors recognised the strategic and spiritual importance of this mountain. They built a castle on its highest ridge — the same castle you can visit today. They looked at this place and decided it was worth defending, worth naming, worth keeping.

When the Christian reconquest came in the 12th century, the name evolved — from Arabic through medieval Portuguese — into the Sintra we pronounce today.

What the Name Carries

Celtic reverence. Roman documentation. Moorish occupation. Christian reconquest. Each civilisation passed through this mountain and left something behind — in the stones, in the gardens, in the name itself.

When I guide visitors through Sintra, I often stop at a viewpoint before we enter any palace or garden. I ask them to look at the mountain — not at the colourful towers of Pena Palace, not at the walls of the Moorish Castle, but at the mountain itself. The granite. The mist. The trees that have been growing here for centuries.

This is what Sintra is, before it is anything else. A place that has been considered sacred, special, and worth naming by every people who ever lived beneath it.

Whatever the true origin of the name — and perhaps we will never know for certain — it has carried something across the centuries that no etymology can fully explain.

Some places simply matter. Sintra is one of them.
