Barú
The Spanish cut a canal here in the late sixteenth century to link Cartagena's bay to the Magdalena River, and in doing so accidentally made an island. That act of colonial engineering is why you're now crossing water to reach Barú — a narrow strip of land, rarely more than a kilometre wide and about twenty-five kilometres long, where the sand runs white and faintly pink and the water is clear enough to read the seabed through it.
Three small towns — Araca, Santa Ana, and Barú itself — account for most of the island's population. The rest is beach, mangrove channel, and the kind of quiet that a place earns by being slightly inconvenient to reach.
💛 What travellers fall for
People who come back tend to do two things differently: they stay the night so they can catch the bioluminescent plankton on an evening outing, and they head to Cholón early — before the reggaeton boats arrive in force — to claim a spot in the shallows while the water is still glassy.

The canal the Spanish dug in the late 1500s to connect Cartagena's bay to the Magdalena River did more than improve trade logistics — it severed Barú from the mainland entirely, turning a peninsula into an island. During the colonial period the island sat at the margins: a few fishing communities, some limestone kilns, and a trade in contraband that moved beyond the reach of Spanish authority.
The town of Barú itself was a palenque — a settlement of escaped enslaved people from Cartagena. In 1708, a naval engagement known as Wager's Action took place off the island's shores, resulting in the sinking of the treasure galleon San José, which still rests on the seabed nearby. A bridge connecting the island to the mainland opened in 2014, ending centuries of enforced isolation.
