1. Tour the Roman Theater and Museum

The Roman Theater of Cartagena is the crown jewel of the city’s archaeological heritage and one of the most striking ancient sites in all of Spain. Built in the 1st century BC and rediscovered only in 1988, it has since been beautifully restored and now serves as both a historical monument and a museum experience. Visitors enter through the museum, where artifacts and audiovisual exhibits tell the story of Roman Cartagena, before stepping out into the open-air grandeur of the semi-circular theater. With a capacity of 6,000 spectators, it’s a breathtaking reminder of the city’s classical importance.

You don’t need to be a history buff to be blown away by the size and preservation of this space. The combination of educational content and physical ruins makes for a deeply immersive experience. It’s centrally located and easy to access, making it a must for any first-time visitor. Come early or late in the day for fewer crowds and better light for photography.

2. Walk the walls of the Concepción Castle

Perched atop a hill and surrounded by lush greenery, Castillo de la Concepción offers one of the best panoramic views of Cartagena’s harbor and old town. The castle, originally built on Roman foundations and later converted into a medieval fortress, now houses a small museum that explains the city’s military past. Visitors can explore the towers, battlements, and walkways while taking in the coastal breeze and watching ships enter the port below. It’s one of the most scenic and educational walks in the city.

Accessed via a short hike or a glass elevator from the city center, the journey is just as enjoyable as the destination. It’s a great place to pause, reflect, and snap incredible photos of the coastline and cityscape. For families, couples, or solo travelers, the castle combines nature, history, and relaxation all in one. Bring water and comfortable shoes for this half-day outing.

3. Stroll the palm-lined Calle Mayor

Calle Mayor is the heartbeat of Cartagena’s historic center and one of the most elegant promenades in southern Spain. Lined with Art Nouveau buildings, boutique shops, and al fresco cafés, the street is a dream for architecture lovers and casual wanderers alike. You can admire the ornate facades of the Gran Hotel and Casino de Cartagena, sip a café con leche, or browse local ceramics and fashion. The entire atmosphere feels like a blend of Spanish sophistication and coastal charm.

Day or night, Calle Mayor is always lively without being overwhelming. Street musicians, public art, and seasonal decorations keep things interesting all year. It’s also a great launching point for side streets that lead to smaller plazas and galleries. Don’t rush this walk—it’s meant to be savored slowly, with frequent stops for snacks and snapshots.

4. Dive into maritime history at the Naval Museum

Given its strategic coastal location, Cartagena has long been a naval powerhouse—and the Museo Naval de Cartagena brings that legacy to life. Located inside a historic naval building, the museum showcases models of ships, weapons, uniforms, and documents tracing Spain’s maritime evolution. One of the highlights is the original Isaac Peral submarine, one of the earliest electric subs ever built. Kids and adults alike will enjoy the interactive displays and life-sized vessels.

The museum is free or low-cost to enter and offers plenty of bilingual signage. It’s an excellent rainy-day activity or mid-afternoon stop. For those interested in technology, history, or military strategy, this museum offers an up-close look at the innovations that made Cartagena a naval legend. Plan for at least an hour to explore all its rooms and exhibits.

5. Explore nature and history on a hike at Cala Cortina

Just a 10-minute drive from the city center, Cala Cortina is a beautiful urban beach tucked between rocky cliffs and hidden military bunkers. The area offers not just swimming and sunbathing but also hiking trails with views of the Mediterranean and remnants of Cartagena’s coastal defenses. You can combine beach time with a light historical hike, spotting abandoned fortifications and learning how this coast was once protected. It’s a unique blend of natural beauty and living history.

Locals love it for a quick escape, and it’s rarely packed outside of summer weekends. There’s a seaside restaurant nearby where you can try fresh seafood after your hike. If you’re looking for something active that also feeds your curiosity, Cala Cortina delivers. Don’t forget to bring sunscreen and your camera—the views are incredible.

6. Visit the Civil War Shelters and learn about Spain’s 20th-century history

Beneath the city lies one of its most moving and educational sites—the Refugios de la Guerra Civil. These preserved air raid shelters offer a glimpse into how civilians survived the bombings during the Spanish Civil War. The museum uses immersive audiovisuals, personal testimonies, and original structures to convey the emotional intensity of that era. It’s a powerful and sobering reminder of the human cost of conflict.

The visit is guided through tunnels built into the hillside beneath Concepción Castle. You’ll walk where thousands once sought refuge and gain a deeper understanding of Cartagena’s resilience. It’s recommended for adults and teens with an interest in modern history. For a complete picture of the city’s past, this stop is essential.

7. Attend the Carthaginians and Romans Festival

Every September, Cartagena transforms into a living history stage with the Carthaginians and Romans Festival, one of the most exciting and immersive reenactments in Spain. Locals dress in full regalia to relive the epic battles, rituals, and daily life from the Second Punic War. Expect parades, gladiator shows, military camps, and cultural exhibitions that span over 10 days. It’s a thrilling way to learn history while celebrating the community’s roots.

Whether you watch the grand battle at the Roman Theater or join in the street festivities, this event is unforgettable. Families, solo travelers, and culture enthusiasts all find something to enjoy. Make sure to check dates in advance and book accommodations early—it’s Cartagena’s biggest annual event. Bring a camera, your curiosity, and a sense of fun.

8. Discover modern art at the Muram Museum

For a fresh contrast to the city’s ancient sites, visit the Muram Museum (Museo Regional de Arte Moderno). Located inside the Palacio Aguirre, a stunning modernist mansion, this gallery showcases contemporary Spanish art from the 19th century to today. Rotating exhibitions include painting, sculpture, photography, and multimedia installations from regional and national artists. The architecture alone is worth a visit—mosaics, stained glass, and curved staircases welcome you into an artistic wonderland.

This is a calm and inspiring way to spend an hour or two, especially if you enjoy quieter, thought-provoking experiences. Admission is often free or affordable, and the museum is centrally located near Calle Mayor. It’s ideal for creatives or anyone looking to explore Cartagena’s more modern cultural identity.

9. Take a boat tour of the port and military harbor

One of the best ways to appreciate Cartagena’s strategic geography is from the water. Harbor boat tours depart daily and take you past ancient walls, forts, shipyards, and lighthouses, with narration explaining how the city has defended itself for centuries. You’ll cruise around the bay while learning about the city’s evolution as a naval power. It’s relaxing, scenic, and informative all in one.

Tours typically last about 45 minutes to an hour, and sunset cruises offer especially beautiful views. Bring a hat and sunglasses for daytime trips, and enjoy the breeze as you glide past centuries of maritime history. For a new perspective—literally and figuratively—a boat tour is well worth your time.

10. Relax at El Batel Auditorium and cultural waterfront

End your trip with a visit to the modern El Batel Auditorium, a sleek waterfront venue that hosts concerts, plays, and exhibitions. The surrounding promenade is a favorite for evening strolls, with its breezy design, seaside sculptures, and outdoor cafés offering views of the harbor. Whether or not you catch a show, it’s a great place to wind down and reflect on your journey through the city. As the sun sets, the area comes alive with soft lights and a relaxed atmosphere.
