How to Spend a Day in Cartagena's Roman Forum and Port Quarter

I walked past the Roman Forum twice before I found it. It was a grey October morning, I had a coffee in one hand and a map I'd printed in the other, and I was looking for something grand. Marble columns, perhaps, with a sign. What I eventually found was a quiet hillside of low stone walls and mosaic floors, tucked behind ordinary apartment blocks, with a woman sweeping leaves off a Roman street. I've been back four times since.

Cartagena is about 40 minutes from our corner of the Mar Menor, and in autumn it's one of the easiest days out you can plan. The heat has gone, the cruise crowds thin out, and the stone is warm enough in the afternoon sun to sit against. Here's how I'd spend the day, based on a good deal of trial and error.

Start at the Roman Theatre, Not the Forum

Park underground near the port (the car parks off Plaza de España are easy to find and I've never had trouble getting a space in October). Then walk up towards the Roman Theatre museum. It's a proper bit of theatre in itself. You go in through the Palacio Pascual de Riquelme, then follow a long tunnel of escalators and passages that tip you out, quite suddenly, at the top of the stone seating.

I sat there for a good twenty minutes the first time. The theatre was built in the late first century BC, and for centuries it was buried under houses and a bullring-era jumble of streets. Standing in the stalls with the cathedral ruins above you and the harbour glinting behind the stage, you get a sense of how much of the town sat under your feet all that time.

Book your ticket ahead if you can, or at least arrive before 10.30. Mornings are the quiet window, and the light on the stone is lovely before midday.

A Word on Shoes

Wear proper soles. Cartagena's old streets are polished marble and cobble, and after a bit of autumn drizzle they turn into an ice rink. I learned that one the hard way outside a tapas bar.

The Forum District and the Hill Behind It

From the theatre it's a short walk uphill to the Barrio del Foro Romano, which is the place I'd walked past. Don't expect a single big square. It's a whole neighbourhood excavated in pieces: the Casa de la Fortuna with its painted walls, the Decumanus (the main Roman street, with the cart ruts still visible), the baths, and the Augusteum, a sanctuary for the cult of the emperor.

What I love is the scale. You're not behind a rope staring at a distant ruin. You walk the actual street where somebody once haggled over fish. The guide at the entrance told me the best time to come is just after the school groups leave, around noon, and she was right. I had the whole Decumanus to myself for ten minutes, apart from a cat who clearly felt the place was his.

After that, I'd go up the hill if your legs are willing. The Castillo de la Concepción sits on top, and in October the views over the harbour and the grey naval ships are as clear as they get. There's a panoramic lift from near the town hall that saves you the climb. I took the stairs the first time and regretted it by the halfway bench.

Lunch, Coffee and the Port Quarter

By one o'clock you'll be hungry, and Cartagena doesn't disappoint. The streets running back from the waterfront have plenty of small places doing a menú del día for about €13 to €15. I usually go for something with local rice or a plate of grilled fish, and finish with a café asiático. If you haven't met one, it's a Cartagena speciality: espresso with condensed milk, a splash of brandy and Licor 43, a little cinnamon and a twist of lemon peel. It's sweet, warming and just right for a cool afternoon. Treat it as dessert and you won't be disappointed.

Eat a bit later than you think you should. Locals sit down around 2 pm, and the places that look empty at 1.15 are full by 2.15.

Walking It Off by the Water

After lunch, wander down to the Paseo Alfonso XII along the harbour. There's the Peral submarine, an astonishing early prototype from the 1880s, parked beside the Naval Museum. The marina is full of yachts and the occasional naval vessel sliding past. In the late afternoon the sun drops behind the hills and the water turns a soft pink, and everyone, from teenagers to grandparents, seems to be out for a stroll.

If you've energy left, the pedestrian Calle Mayor is lovely for window-shopping and for looking up at the modernist facades. Some of the buildings are very ornate, others are just a bit worn, and both are worth a look.

Making a Proper Day of It

Here's roughly how mine goes now. I leave Los Alcázares by about 8.45, reach the theatre for opening, do the Forum by late morning, eat at two, and have a slow harbour walk afterwards. I'm usually back on the Mar Menor shore for sunset, which feels like a bonus.

If you're still planning where to stay, our area guide to Los Alcázares and the Mar Menor explains how easily Cartagena, Murcia and the coast fit into one base. Many of the holiday rentals near Roda Golf are an easy drive from the motorway, which makes a day like this simple. And if you're also here for the fairways, you can fit a morning round in before heading to the city, as the golf courses around Roda usually have good early tee times in autumn.

For more days out like this one, browse our sightseeing guides around the Costa Cálida. And if you only take one tip from me, make it this: go slowly in Cartagena. The best moments aren't on the ticket. They're the woman with the broom, the cat on the Roman street, and the last warm minutes of sun on the harbour wall.
