Mamonal
Mamonal is not a place you come to for the view. It sits on the eastern shore of Cartagena Bay as a working industrial zone — thermal power stations, dry docks, fuel terminals, the kind of infrastructure that keeps a port city alive but rarely gets credited for it. Before any of this, the Cospique people lived along this same stretch of coastline, and the ground underneath the refineries has its own long history.
What draws a specific kind of visitor here is COTECMAR, the Colombian naval shipyard, where a 186,000-square-meter complex of eleven docks produced the ARC 24 de Julio — a 93-meter ocean patrol vessel built entirely by Colombian engineers, commissioned in 2026.
💛 What travellers fall for
People who come back to this corner of Cartagena Bay tend to be engineers, maritime journalists, or logistics professionals. They'll tell you to sort your access credentials well in advance, that the C001 bus along Vía Mamonal runs early — first departure at 4:33 AM — and that you should base yourself in Cartagena proper rather than trying to stay in Mamonal itself.

Before Mamonal became synonymous with industry, the Cospique people inhabited this stretch of Cartagena Bay's exterior coast. The zone's modern identity is industrial and relatively recent — built around port activity, energy generation, and naval construction rather than colonial architecture or civic ceremony.
The port at Mamonal handled coal shipments until early 2013, when those operations ceased indefinitely. The more consequential chapter has been the growth of COTECMAR, the naval shipyard whose 186,000-square-meter facility became the site of a genuine engineering milestone: the design and construction of the ARC 24 de Julio, a 93-meter patrol vessel built by Colombian hands, a project that generated over 3,300 direct and indirect jobs in the process.

When to go
Cartagena Bay sits in a tropical zone with a pronounced dry season from December through March — low humidity, reliable sun, and little rain. The shoulder months of April and May see the first rains returning, but prices in the wider area drop noticeably.
