Salitrillos

About Salitrillos:

Salitrillos covers 14.34 km² in the north of the canton of Aserrí. Desamparados wraps around it on the north and east, the districts of Aserrí and Tarbaca lie to the west, and San Gabriel lies to the south. Two national roads run through it: Route 209, the road from San José through Desamparados into Aserrí, and Route 304, which leaves San Miguel de Desamparados and heads towards Cartago. The canton seat is about 11 km from San José, and the San José – Aserrí – Salitrillos bus runs from the city centre through Aserrí and Cinco Esquinas to its own terminal in the district. Try the trip at rush hour before you commit to a house.

Most of the district is urban, with rural pockets on the higher ground. Santa Teresita and part of Cinco Esquinas are the main barrios, and the outlying communities include Lagunillas, Palo Blanco, Guinealillo, Cuesta Grande, Quebradas, Rincón and El Cerro, along with Jericó, Nazareth, Los Itabos, La Flor and Roca Fuerte. The CTP de Aserrí, the canton’s technical high school, is here, together with the Domingo Faustino Sarmiento, Santa Teresita and Sauréz primary schools and a CEN child-care centre. Shops, services and the municipal offices are in Aserrí town, a short ride away. Between them, the Aserrí and Salitrillos districts hold about seven in ten of the canton’s residents.

The district sits at a mean altitude of 1,323 metres, on the slopes that rise from the Desamparados side towards the hills of Aserrí. Water is the issue to understand before anything else. Supply comes from the Aserrí municipal aqueduct rather than the national water utility, and since April 2026 the canton has run sector-by-sector rationing with tanker trucks filling the gaps, while the municipality brought a new well into service in Lagunillas. Slopes and riverbanks matter too: the Río Cañas undercut the bank below Urbanización Santa Elena badly enough to leave several homes exposed until a retaining wall went in, and Barrio Santa Teresita got a protection wall of its own.

Salitrillos grew from 11,148 people in 2000 to 13,676 in 2011, and the 2022 estimate is slightly lower, so this is a settled district rather than a building site. The housing is mostly detached family homes on their own lots, a few urbanizaciones such as Santa Elena, and larger parcels toward the rural edges. Above Cinco Esquinas the road climbs to Las Mercedes, where a trail through coffee and farm plots leads to the Piedra de Aserrí, a rock outcrop more than 100 metres high whose iron cross can be seen from Cinco Esquinas. For anyone working in Desamparados or southern San José, it puts a house with a yard within a bus ride of the job.

Houses in Salitrillos:

Most houses for sale in Salitrillos are family homes built on their own lot, and some come with a second entrance or a yard large enough to add a small unit. Land sizes run from a few hundred square metres in the barrios to several thousand further out. Ask how the house gets its water and whether it has a storage tank before you look at anything else.

Land and Lots in Salitrillos:

Building plots with water and electricity at the road come up in the residential areas, from around 500 m² to well over 1,000 m², and larger parcels appear toward the rural edge of the district. On sloping land, find out where the lot sits relative to the nearest stream before you pay for a survey. Get a water availability letter from the municipal aqueduct first, because a building permit depends on it.

Rentals in Salitrillos:

The rental stock is mostly small houses and apartments let by local owners, some within walking distance of the last bus stop. This is neighbourhood housing, not condominium living with amenities. Ask the landlord how the street has fared under rationing and whether the place has a water tank.

FAQ:

• Is Salitrillos part of Aserrí or Desamparados?

  Aserrí. Desamparados borders it on two sides, and streets such as Calle Lajas are split between Salitrillos and San Miguel de Desamparados, so confirm on the cadastral plan which canton a property is in. That decides which municipality handles permits, land-use certificates and property tax.

• How do I get to San José without a car?

  The San José – Aserrí – Salitrillos bus runs from the city centre via Aserrí and Cinco Esquinas to its terminal in the district. By car, Route 209 links the district to Desamparados and San José, and Route 304 heads east toward Cartago.

• How reliable is the water supply?

  It has been the canton’s weak point. Aserrí runs its own municipal aqueduct, and in 2026 it rationed supply by sector and sent tanker trucks while a new well in Lagunillas came into service. Ask the aqueduct for a water availability letter for the exact property, and budget for a storage tank.

• What should I check before buying a lot on a slope or near the Río Cañas?

  Look at how the land falls toward the nearest watercourse: erosion along the Río Cañas below Santa Elena was serious enough to need an emergency retaining wall. Check the title and cadastral plan at the Registro Nacional, ask the Municipalidad de Aserrí for a land-use certificate, and confirm the protected strip along any river or stream, where you cannot build.

• What is there to do nearby?

  The walk to the Piedra de Aserrí starts above Cinco Esquinas, and the view from the top takes in the Central Valley and its volcanoes. Tarbaca, the next district west, is where the canton’s lookouts and restaurants are.
