Scuba Diving & Snorkelling

Enclosed within a protective wall reaching up to 20 m in width, the Ciudad Amurallada (or "Walled City") is Cartagena's old beating heart. Packed with well-preserved colonial buildings, it's a pleasure to stroll through; its streets of colourful low-rise merchant homes marked by iconic balconies are now mostly walked by either tourists or students who attend classes at the University of Cartagena during the day and linger for meals and nightlife after school is out. Cafes in Plaza Aduana and Plaza Santo Domingo teem with patrons, forging an incredibly jovial atmosphere; the districts of San Diego and El Centro are two not to be missed. There is plenty of food and shopping to be had, with a mixed bag of world-class restaurants and street food hawkers and the incredibly photogenic palenqueras — women dressed in vibrantly coloured clothing selling fruit in the streets — images of whom have become emblematic of Colombia as a travel destination.

Visible from almost everywhere in Cartagena, the Convent of Santa Cruz de la Popa all the way up the a 150-meter hill known as Mt. Popa. The hill got its name for resembling a poop deck of a ship. After four centuries of varied history, the convent itself is now open as a religious museum. From the top Mt. Popa you’ll get the best panoramic views of Cartagena and its beaches. The fastest and least stressful way up the hill is with a taxi (be sure to haggle on the price). An important tip : if you take a taxi or a car service to this location, pay them a few pesos to wait for you to drive you back. The taxis on top are all already "reserved" and Uber drivers are not eager to drive all the way to the top to pick you up.

Museo del Oro Zenú is Cartagena's response to the famous gold museum in Bogotá. Here you'll learn about the culture of the Zenú people through the artefacts of their tribe: over 600 gold, silver and ceramic pieces are on display. Other highlights include displays on body painting and textiles, and an exhibit focusing on the engineering prowess of the Zenú — learn how they built a vast network of canals over 2,500 years ago.

Just an hour's boat trip away from Cartagena lie the magnificent Rosario Islands, which belong to Colombia's only underwater natural park (the Rosario and San Bernardo Corals National Natural Park). Abundant marine wildlife (including over 50 species of corals) and some of Colombia's best beaches draw in many in search of relaxation and active pursuits such as snorkelling and diving. Isla Grande is best for kayaking through unique mangrove forests and seeing the phosphorescent plankton light up the waters of a brackish lake at night, while Playa Blanca is Cartagena's most spectacular white-sand beach (also reachable by land). It should be said that the company you choose to tour with has the potential to make or break the experience. Low cost tours can mean multiple intermediate stops en route to your destination, as well as unpleasant surprises such as no transfer back to your hotel. Try and choose a trusted company with consistently good reviews, or opt for a private tour. Mind that seas may be rough at certain times of the year, particularly in December and January, when tours on smaller boats may even become dangerous.
