San Isidro
Real Estate in San Isidro, Costa Rica.
The turn-off at Cuatro Cruces, where drivers leave the Interamericana for Miramar, sits inside San Isidro, and a new interchange is being built on exactly that spot. From there the district runs north through cane fields and cattle pasture toward the hills of Montes de Oro, the inland canton of Puntarenas province in Costa Rica. Most homes line the road up to Miramar, in the village of San Isidro and the hamlets around it. The property for sale in San Isidro is mostly three-bedroom family houses, building lots in a few small subdivisions and larger pasture or plantation parcels away from the highway. It suits people who work in Puntarenas, Esparza or at the El Palmar mill and want a house with a yard a short drive from the job.

About San Isidro:
San Isidro is the third district of Montes de Oro, about 58 square kilometres wedged between Miramar, the canton seat, to the north, the central canton of Puntarenas to the south and west, and Esparza to the east. Rivers draw most of those lines: the Río Seco on the Miramar side, the San Miguel toward Puntarenas and the Guatuso toward Esparza. The Interamericana Norte cuts across the southwest corner, and at Cuatro Cruces Route 144 branches off north, through the village of San Isidro and on to Miramar about seven kilometres away. The Puntarenas–Miramar buses run that road, Puntarenas city is around half an hour’s drive, and San José about an hour and a half.
That corner is about to look very different. The widening of Route 1 to four lanes between Barranca and Limonal includes a grade-separated interchange at Cuatro Cruces, new bridges over the rivers in this stretch and kilometres of side roads, on a two-year contract that started in January 2026. The highway already carries a large share of the country’s exports to the port at Caldera, so heavy traffic is nothing new here. The change is in how land beside the road is reached, and that matters to anyone weighing a lot or a business with frontage on Route 1.
Cane and cattle set the rhythm. The El Palmar sugar mill, opened in the late 1950s a kilometre south of Cuatro Cruces, grinds cane from Montes de Oro, Puntarenas and Abangares and is one of the area’s big employers. Off the highway the land is mostly pasture for beef and dual-purpose herds, with large teak and melina plantations and small plots of maize and cane. The district was created in 1915 as El Tigre; residents objected to being named after a wild animal, the government renamed it Aguilar in 1918, and a second petition finally gave them San Isidro, after the farmers’ patron saint, whose day is 15 May. Older locals still get called tigreños.
The ground is low and hot near the Interamericana and rises toward the Cerro del Diablo, a little over 500 metres, by the Esparza boundary. This is the dry Pacific, and here water counts for more than the view: find out where a lot’s water comes from before you fall for it. Daily life runs along the main street, with the school, the sports ground, the chapel, the community hall, the health centre and the shops, while Santa Rosa, Ciruelas, La Isla, Aguabuena and Tiocinto spread out into the countryside. Aguabuena is named after hot springs that used to be a weekend outing for families from all over the canton. The housing is mostly built by and for local families, though a few larger hillside parcels carry houses with pools and a view of the sea.
Houses in San Isidro:
Most houses for sale are single-storey, three-bedroom family homes on lots of a couple of hundred square metres, on the main street or the side streets of the village. New builds turn up too, some sold semi-furnished. Further out, a few houses stand on parcels of several thousand square metres, sometimes with a pool and a view over the lowlands to the Gulf of Nicoya. Listings often say Miramar even when the house sits in San Isidro, so check the district on the cadastral plan before you compare it with homes in the canton seat. If you will not be driving every day, see how far the house is from the Miramar bus stop.
Land and Lots in San Isidro:
Land here comes in three sizes. There are building lots in small subdivisions such as Urbanización Los Olivos, residential parcels of around half a hectare near the village, and pasture or plantation land measured in hectares further from the highway. A lot on the Interamericana deserves a second look while the widening is under way, because the interchange and the side roads change how it connects to traffic. On farmland, ask what is planted: teak and melina are long-term crops, and a stand of timber affects both the price and what you can do with the ground. Several rivers cross the district, and the protected strip along their banks cannot be built on.
FAQ:
-
Is a property listed as Miramar really in San Isidro?
Often, yes. The canton seat is next door and many people use “Miramar” as the address for the whole canton. Both districts answer to the same municipality, but the cadastral plan shows exactly where the land lies, and that tells you whether it is near the village, a river or the highway.
-
How does the Route 1 widening affect land near Cuatro Cruces?
The works run inside the highway right-of-way, and the interchange and side roads can change how individual properties reach the road. Before buying anything with frontage on Route 1, ask MOPT whether the parcel is affected and where its entrance will be once the works are finished.
-
What should I check on title before buying a farm here?
Three local risks come up: a boundary that follows a river, a strip taken for the highway, and family land shared among heirs but never formally divided. Look the property up at the Registro Nacional (Registro Inmobiliario) for owner, liens and plan, walk the fences against that plan, and get a land-use certificate from the Municipalidad de Montes de Oro before you design anything.
-
Is water a concern in San Isidro?
It is a dry area with a long dry season, so water is the first thing to settle. For a lot, ask for a water availability letter from the local provider; for a farm, find out whether water comes from a well, a spring or a river concession, and whether that right is in the owner’s name.
-
How far is San Isidro from the beach?
Montes de Oro has no coastline, so the beach means a drive to Puntarenas, around half an hour. In return, parts of the district look out over the Gulf of Nicoya.
