Eco-Friendly Hotels in Cartagena — Your 2026 Guide to Sustainable Stays

Why Cartagena for Sustainable Travel

Cartagena's compact historic centre is one of the most walkable cities in the Americas. The Walled City (Ciudad Amurallada) is roughly 1.5 by 1 kilometre — everything inside is accessible on foot. Getsemaní, the adjacent neighbourhood, is another 15-minute walk. This walkability eliminates the need for taxis for most sightseeing. The city's bus system and boat taxis to Islas del Rosario provide car-free alternatives for longer journeys.

The Rosario Islands — a protected national park 90 minutes by boat — offer world-class snorkelling, coral reefs, and mangrove forests. Local conservation organisations run sustainable tourism programmes that limit daily visitor numbers and fund reef restoration. Back in the city, Cartagena's food scene sources seafood from sustainable fisheries along the Caribbean coast. The Bazurto Market is a sensory explosion where catch-of-the-day arrives at dawn from nearby fishing villages.

Hotels within the Walled City are overwhelmingly housed in restored colonial buildings. Many have adopted rainwater harvesting, solar water heating, and locally crafted furnishings. The thick stone walls and high ceilings characteristic of Cartagena's colonial architecture create natural cooling — reducing the energy needed for air conditioning.

Walled City (Ciudad Amurallada)

Historic Cartagena within the 16th-century walls is a UNESCO World Heritage site with boutique hotels in converted mansions. Stay in Santa Catalina or Santo Domingo neighbourhoods for cobblestone streets, plaza-front cafes, and five-minute walks to the Torre del Reloj and San Felipe Castle.

Getsemaní — The Creative Quarter

Once considered the wrong side of the wall, Getsemaní is now Cartagena's most vibrant neighbourhood. Plaza de la Trinidad is the social hub — street food, live music, and local art. Guesthouses here are generally more affordable than inside the walled city, and the neighbourhood's energy is authentically Cartagenan.
