From March 4 to June 10, 2026, archaeologists worked through 12 sectors of former banana land at Palmar Sur. They recorded evidence of human occupation dating from AD 800 to 1500. They found no stone spheres, causeways or cobblestone pavements in the airport's impact area. They also did the most physical work the Southern Zone International Airport has seen in more than two decades of planning. Their final technical report is due at the National Archaeological Commission this month, October 2026.
Anyone shopping for property along Costa Ballena will hear about this airport. People mention it as the thing that will bring Uvita closer to the rest of the world. The project is real and the government is still pursuing it. But its main obstacle is no longer the archaeology, the land or the runway. The bigger problem is the demand forecast. Official passenger expectations for this airport have shrunk to a fraction of what the original plan assumed, so a buyer is better off pricing Uvita on the access that exists in 2026.
What exists at Palmar Sur as of October 2026
The proposed site sits on Fincas 8, 9, 10 and 11, former banana plantations owned by the Compañía Bananera de Costa Rica until 1984. Ownership later passed to the state, mainly through Inder and Infocoop. The idea goes back to the early 2000s. The first technical master plan was completed in 2008. Since then the airport has appeared in the development agendas of the Pacheco, Arias, Chinchilla, Chaves and now Fernández administrations without reaching construction.
Here is where each piece of the project stands on the public record:
| Milestone | Status | Most recent source |
|---|---|---|
| Archaeological evaluation of 131.5 hectares in Fincas 8–11 | Final report approved by the National Archaeological Commission, February 11, 2025 | Delfino, July 2025 |
| Archaeological rescue at 12 sites | Fieldwork completed March 4 to June 10, 2026; final report due October 2026 | Tico Times, July 5, 2026 |
| Updated master plan to replace the 2008 version | In progress at MOPT through the Civil Aviation General Directorate | Tico Times, June 22, 2026 |
| Environmental impact study | Earlier study on hold, without final approval | Tico Times, June 22, 2026 |
| Construction financing, final design, construction tender | Not found in any official source reviewed | — |
The archaeology was paid for in stages. The 2024 evaluation cost US$560,000, financed by COCESNA, the Central American air navigation services corporation, under technical and financial supervision from the Civil Aviation General Directorate. In January 2026, a DGAC and CETAC management report still listed funding for the rescue work as something the council had asked COCESNA for again. That fieldwork has now been completed. Tico Times summed up the situation in June: with the archaeology done, the project is "technically eligible to move forward, but only after a new master plan replaces the outdated 2008 version."
The forecast that shrank
That new master plan matters because it has to answer the question the 2008 plan answered very generously: how many people would actually fly here.
The 2008 master plan expected nearly one million passengers a year by 2030. Costa Rica's current National Airport Plan projects about 126,000 passengers by 2039 and about 242,000 by 2043. The newer forecast comes in at roughly one-eighth of the old one, nine years later. Even the 2043 figure is about a quarter of what planners once expected by 2030.
Spread across a year, 126,000 passengers works out to about 345 people a day. At 242,000, it is about 660 a day. For scale, Juan Santamaría International handled a record 28,714 international passengers on a single day, January 3, 2026, during a high season that saw 3,215,208 international-terminal passengers between November 2025 and April 5, 2026.
This is why the Federated College of Engineers and Architects, the CFIA, which supports the broader idea of a southern airport, says the new study has to reassess runway length, land needs, financing and, above all, realistic passenger demand. The CFIA lists profitability among the project's major unresolved problems. The 2023 technical studies called for a runway of about 2,600 meters. Whether a new master plan built on a demand curve of a few hundred passengers a day still justifies that runway is the question it now has to settle.
Supporters have real points too. Tourism across the southern Pacific keeps growing, and a third international gateway could take pressure off Juan Santamaría and Liberia. Those arguments now run into a forecast that the government's own planning documents have revised sharply downward.
Why the calendar keeps moving
A smaller forecast weakens the business case. Several other constraints keep the timeline loose.
In July 2025, MOPT minister Efraim Zeledón said a tender for environmental, geological and hydraulic studies would be ready that half-year, with the studies carried out in the first half of 2026 and the master plan defining the technical details after that. By late June 2026, reporting still described the master-plan update as unfinished. Our review of sources published since then turned up archaeology updates, but no master-plan tender, construction budget or construction date.
The site also comes with specific sensitivities, described in the June 2026 Tico Times report:
- More than 350 farming families live on Fincas 9 and 10, many of whom have worked that land since 1984. Organizations representing them have used legal challenges and public demonstrations against the project.
- The site lies less than one kilometer from the Térraba-Sierpe National Wetland, the largest wetland on Costa Rica's Pacific coast and a Ramsar site.
- It sits near the Finca 6 archaeological park, part of the pre-Columbian stone sphere sites designated a UNESCO World Heritage Site in 2014.
- The earlier environmental impact study drew criticism over data quality, methodology and community consultation, and remains without final approval.
The government's own list of priorities also shows where the airport stands. On August 21, 2026, Tico Times reported a national aviation package with three pieces: close to $30 million to modernize Tobías Bolaños in Pavas and move domestic flights there, ₡3,000 million to expand the private-aircraft apron at Liberia's Daniel Oduber Quirós International, and a planned expansion at Limón. Palmar Sur was not among them.
The access an Uvita buyer is actually pricing
Uvita's reachability today depends on Quepos and the coastal highway.
SANSA advertises daily direct flights from San José to Quepos, about 30 minutes in the air. Its destinations directory lists Quepos and does not list Palmar Sur. On the ground, route-planning estimates put Uvita about 63 kilometers and just over an hour from Quepos. They put Juan Santamaría International about 160 kilometers and roughly three hours and 40 minutes away by car.
That highway is getting tangible investment. On September 30, 2026, MOPT and CONAVI reported $34,943,127 across nine PROERI works on Route 34, the Costanera Sur, spanning Garabito, Parrita, Quepos and Osa. The works include bridge projects at Tárcoles, Parrita and Savegre and repair of the Coronado River bridge in Osa. For anyone who drives between Uvita and the capital, those bridges are the infrastructure story with dollar figures attached this year.
One change to watch on the flight side is the Pavas plan. If domestic departures move from Juan Santamaría to Tobías Bolaños, an international arrival connecting to a Quepos flight would need a ground transfer between two airports. The government has not published a date, and nothing changes for flights already booked this season. Demand on the international side keeps rising. Arrivals reached 2,001,660 through July 2026, up 6.4% over the same period in 2025, and United opens a Washington-Dulles route into Liberia on December 17.
Reading the airport line in a listing
A price that already counts on the airport assumes several milestones that have not happened. Each of these would show up on the public record:
- The National Archaeological Commission receiving the final rescue report, expected October 2026.
- A published updated master plan from MOPT and DGAC, with its revised demand forecast and runway length.
- Environmental approval through SETENA, which the earlier study never received.
- A financing source and a construction tender.
Until the second step appears, the airport works like an option with no expiry date and no confirmed exercise price. It can be weighed in a purchase decision, and buyers will weigh it differently. The value of a Uvita property can still be measured today through the Quepos flight, the drive time on Route 34 and the bridges MOPT is funding now.
Frequently Asked Questions
Has construction started on the Palmar Sur airport? No. As of the most recent reporting, the completed work is archaeological. The project still needs a new master plan and environmental approval.
Is there an official construction budget? No adopted construction budget or financing package turned up in the government sources reviewed. Figures circulating online come from advocacy groups and are not government budgets.
Can you fly to Palmar Sur today? SANSA's current destination list includes Quepos but not Palmar Sur, which makes Quepos the scheduled air link most often used for Uvita.
