Mexico's Caribbean coast is quietly upgrading its maritime backbone. The Integral Port Administration of Quintana Roo (Apiqroo) has finalised two addenda to its federal concession that expand the land and water it manages by 45.64% — the first change to the title in over a decade.

The details matter for anyone who travels by sea in the state. The Fifth Addendum, formalised in 2023, brought maritime and port zones in Cozumel, Isla Mujeres, Playa del Carmen and the southern municipality of Othón P. Blanco under Apiqroo's remit — including Cozumel's north, central and south zones, Marina Cozumel, water areas at Chetumal, La Aguada and Mahahual, and the busy Playa del Carmen passenger route that ferries visitors to Cozumel.

The Sixth Addendum, published in the Official Gazette on November 10, 2026, is even more specific: it added just over 601,700 square metres to Isla Mujeres, taking the island's authorised port area from roughly 13,000 to nearly 614,700 square metres, split between water and a smaller strip of land.

So what changes for travellers? On paper, quite a bit. Apiqroo says better-defined port boundaries will allow tighter control of docks, vessels and facilities — especially on Isla Mujeres, where fishing boats, ferries and tour operators all share the same waterfront. Expect improved surveillance and lighting in port areas, plus cleaner coordination with the Port Authority on vessel arrivals and departures.

There's also a paperwork bonus. Fishermen, tour operators and concession holders will now handle permits and contracts for these areas directly with Apiqroo in Quintana Roo, rather than making trips to Mexico City for federal sign-off. That should speed up the services visitors ultimately rely on: ferry terminals, dive boats, fishing charters and marina berths.

Apiqroo also frames the expansion as an environmental safeguard — clearer oversight means projects in these zones face stricter checks that they hold the right permits. And with better planning of port space, the agency is signalling future upgrades to docks, passenger services and commercial offerings.

For holidaymakers, none of this changes the beach. But it touches almost everything on the water: the ultramar ferry from Playa del Carmen to Cozumel, the catamarans and snorkel trips out of Isla Mujeres, the fishing cooperatives in Mahahual and the cruise-adjacent marinas around Cozumel. Smoother port administration usually means fewer bottlenecks at the dock and, over time, better-maintained terminals. If you're planning a Riviera Maya trip with island hopping or a charter in the mix, the ports you'll use are now on a firmer administrative footing than they've been since the 1990s — with room to grow.
