Land and Farms for Sale in Osa, Costa Rica: Ojochal to Palmar Norte (2026)

Where should I buy land between Ojochal and Palmar Norte?

It depends on what you want the land for. For an ocean-view building lot close to Ojochal's restaurants and services, look first at Tres Ríos de Osa, Coronado and the hills of San Buenas. Chontales is an older pueblo that is now mostly dominated one large lot development that was developed by Ventanas del Pacífico. They built the roads and infrastructure and sold the lots, and other builders build there. For services, Ciudad Cortés is the seat of the canton, with the Municipalidad de Osa and the regional hospital. For farms, ranches and river land, look at the Río Térraba valley around Palmar Norte, Palmar Sur and Sierpe. For large acreage, look at Chacarita, at the south end. Wherever you look, check three things before you get serious: water (an ASADA letter or a registered well or spring), legal access (a public road or a registered easement) which affects what you can build and what you can use the land for, and, for low land, the CNE flood map information for that lot. Compare the price per hectare by town in the table below.

Land prices by town in 2026, per hectare

These are asking prices of the land listed for sale right now, from every agency. A price per hectare mixes small lots and large farms and occasionally lard land with a house, so read it as a rough guide, not an appraisal.

What does land cost per hectare in Osa canton?

One hectare is 10,000 square meters, about 2.47 acres. Farms are usually priced by the hectare, and building lots by the square meter, so a single number for the whole canton hides more than it shows. The table above splits it by town. Within a town, the price per hectare usually moves with a few things you can check: ocean view or not, frontage on a paved road, how much of the land is flat enough to use, legal water, and whether part of it is protected forest or river setback. A large farm usually costs less per hectare than a small lot in the same town, because you are buying land you will not build on. If you are comparing two farms, compare the usable hectares, not the total.

Ask for a property report

Pick a property from this page and leave your name, email and phone. I can send you a report with more information on it. Depending on what the public records show, it may include:

• Flood and landslide zones, protected areas and elevation, from the government maps
• The property outline on a map
• The size on the plano compared with the size in the listing
• Road access
• The government reference land values for the area
• Registry details: the plano's status and date, the land use it is registered for, and any liens or annotations on the title

Based on public records, not a survey or a title review. Your attorney does the full due diligence.

Water availability: ASADA letters, wells and springs

Water is the first thing I check on land in Osa. In most towns here, drinking water comes from the local ASADA, the community water board, which works under AyA. For a building lot, we will ask for a letter of water availability from the ASADA. On farms outside an ASADA's network, water usually comes from a well or a spring, and those need to be registered or permitted through the Dirección de Agua (MINAE). A spring on the property is not the same as the right to use it, so we will ask for the paperwork, not only a look at the water (it is common for sellers to play games and treat the presence of water as the same as "legal water" which would be necessary to obtain a building permit).

Flood risk: the Térraba valley and the CNE flood map

Flood questions come up most for low land along the Río Térraba, around Palmar Norte, Palmar Sur and Ciudad Cortés. Hillside land has a different question, landslides. My answer for any lot is the same: part of the due diligence is to check the CNE flood map for that lot, and often times the uso de suelo document will also include any known risks like this, but it is important to ask if it will affect your building plans. The CNE is Costa Rica's national emergency commission and publishes the hazard maps by canton. Sometimes we can also ask neighbors where the water went in the last big storm (locals remember), but this is anecdotal and should be treated as such.

Building permits, SETENA and land use in Osa

The Municipalidad de Osa, in Ciudad Cortés, issues the uso de suelo (the land-use certificate) and the building permits for this whole stretch. Splitting a farm into lots, or a larger project, also may go through an environmental review with SETENA when the project needs it. Which projects need it is a question for your attorney. Cutting trees and building near rivers and springs are limited by the Ley Forestal 7575, and protected areas are managed by SINAC. Near the Sierpe mangroves, check with SINAC (MINAE) and the Municipalidad for that lot.

Roads and access

The Costanera Sur, the paved coast highway, runs through every town on this page, and at Palmar Norte it meets the Interamericana (the Pan-American Highway). Off the highway, access is where farms differ most. Legal access means a public road or a registered easement (servidumbre) on the plano, not a path a neighbor lets you use. In Chontales, Ventanas del Pacífico built the roads in its lot development and they are public or in some cases private (condo). Farm roads off the highway are almost always gravel, and some need 4x4 in the rainy season (or all year for that matter).

Internet and services

Ciudad Cortés has the Municipalidad de Osa and the regional hospital. Palmar Norte is the working town at the highway junction. Fiber internet is available in the bigger towns, including Ciudad Cortés and Palmar Norte, and sometimes out in the country. On farms, most people use Starlink or a similar satellite service or just use their cellphones.

Why investors are looking at this stretch

Land between Ojochal and Chacarita is mostly farms and large parcels, most of them owned by Costa Rican families. Compare the price per hectare by town in the table above. What people watch here:

• The Costanera Sur, the paved coast highway, runs through every town on this page.
• Ciudad Cortés is the seat of the canton, with the Municipalidad de Osa and the regional hospital.
• Palmar Sur has a small domestic airport with a few regional flights a day at most (sometimes none).
• The government is studying the area for tourism, including a southern international airport near Palmar Sur and Sierpe. Studies and a master plan are in progress (AmeliaRueda.com, July 2025). It has been discussed for decades, financing is not settled and it has opposition (The Tico Times, March 2026). It is a real possibility, not something to time a purchase around.

Land that is not online yet

Many local landowners sell directly, person to person, through an informal network of locals and a faded Se Vende sign hanging precariously off a barbed-wire fence. These properties exist in a fragmented, informal market, and I can help you access it. My local team finds titled land before it is listed anywhere formally. I share the general area, the size, the main features and the asking price up front. I share the exact location and the details once I have a better idea of what you are looking for, and after we have talked through how this market works.

Off-market land works a little differently. The owner is not working with a listing agency in a formal way: the land is offered through an informal local market that foreigners usually cannot reach. We get you in the door. The commission is typically paid by you, the buyer, instead of the seller. In return, these properties are typically priced closer to what local owners would ask of each other, which will often make up for the extra commission on your part. I walk you through how it works, guide you, and share market insight that few others have.

The towns between Ojochal and Chacarita

• Tres Ríos de Osa and Coronado de Osa: hillside building lots with ocean and river views, close to Ojochal. Not Tres Ríos in Cartago, and not Coronado in San José.
• San Buenas: larger parcels and development land next to Tres Ríos, and the Osa Golf Course (formerly San Buenas Golf Resort), a 9-hole course in the town of San Buenas with easy paved access from the highway.
• Punta Mala: a small community along the Costanera Sur with farm land and building sites for modest homes.
• Ventanas: Playa Ventanas (the beach) and the Cinco Ventanas Road are two separate places, not far from one another.
• Chontales: an existing modest pueblo that is now mostly dominated by one large lot development, where Ventanas del Pacífico built the roads and infrastructure and sold the lots.  There are also other plots there, but mostly revolves around a handful of smaller barrios developed by VdP.
• Ciudad Cortés (often spelled Cortez): the seat of the canton, with the Municipalidad de Osa and the regional hospital.
• Palmar Norte, Palmar Sur and Sierpe: the Río Térraba valley, with farms, ranches and river land.
• Chacarita: large farms and jungle parcels at the south end of the area.

Osa canton is not the Osa Peninsula

When people say "Osa" they often mean the Osa Peninsula and Corcovado. This page covers the mainland side of the canton of Osa, along the coast highway between Ojochal and Chacarita. For Ojochal itself, see Ojochal real estate, or Ojochal Costa Rica real estate for a local guide.

Farms, development land and building lots

A building lot is a parcel ready for one home, ideally with a water letter and road access already in place. A farm or finca is larger, often pasture, fruit or forest. Development land is a bigger parcel bought to be split or built out over time. Splitting land into lots needs approval from the Municipalidad de Osa, and each new lot needs its own plano, so your attorney and surveyor handle that process. See all farms for sale and development land on the South Pacific.

How I check land before you get serious

Before you get serious, I pull the plano and the property records so you know in more detail what you're looking at. Your attorney does the full title review as part of the due diligence process, but I can do an initial look with the information at hand, or with the information you provide. I also look at:

• Water: a letter from the local ASADA, or a registered well or spring. Often we will take the seller's word for it during the initial listing, but they must provide documents during the due diligence process
• Access: a public road, or a registered easement (servidumbre). Important to know how you plan to use the property as road access can heavily impact the potential use for a property.
• Land use: the uso de suelo from the Municipalidad de Osa in Ciudad Cortés.
• Flood and landslide risk: the CNE hazard map for that lot.
