Location

Los Chiles, Costa Rica

Los Chiles Airport is a small general aviation airstrip located in Los Chiles, a town in the Alajuela province of northern Costa Rica, near the border with Nicaragua. It serves primarily light aircraft and occasional charter or regional flights connecting the remote area to other parts of Costa Rica. The airport is classified under ICAO code MRLC and holds the IATA designator LSL. Due to its limited infrastructure and the small population of the surrounding region, it sees minimal scheduled commercial traffic and functions mainly as a domestic feeder facility. Los Chiles itself is a gateway community near the San Juan River and Caño Negro Wildlife Refuge, and the airport supports access to these ecotourism destinations for travelers who prefer air travel over the long road journey from San José.

City & Place Guide

Gateway to Nicaragua and wild Nicaraguan wetland adventures

Los Chiles is a small, laid-back border town in northern Costa Rica, situated on the Río Frío near the Nicaraguan frontier. It serves primarily as a transit point for travelers crossing into Nicaragua by boat, but its surrounding wetlands and wildlife make it a worthwhile destination in its own right.

The town sits at the edge of the Caño Negro Wildlife Refuge lowlands, one of Costa Rica's most important wetland ecosystems. Birdwatchers, wildlife enthusiasts, and anglers are drawn here for its exceptional biodiversity, including caimans, river turtles, roseate spoonbills, and Nicaraguan grackles. The pace is slow, the prices are low, and the experience is authentically local.

•Caño Negro Wildlife Refuge — legendary wetland for birding and wildlife boat tours
•Río Frío boat tours — spot caimans, monkeys, and exotic birds along forested riverbanks
•Los Chiles border crossing — scenic river-based crossing into San Carlos, Nicaragua
•Local waterfront — relaxed riverside area good for watching daily town life
•Fishing on Río Frío — tarpon and snook attract serious sport fishers year-round
•Laguna de Caño Negro — seasonal lake teeming with migratory birds and aquatic life

Getting around: Los Chiles is accessible by direct bus from Ciudad Quesada (San Carlos), which connects onward to San José. Within town, walking covers most needs, and taxis are available for trips to boat docks or nearby villages. There is no rail service, and rideshare apps like Uber do not operate reliably here. Boats on the Río Frío are the primary mode of transport for wildlife tours and the Nicaragua crossing.

Best time: The dry season from December to April offers the easiest access and best wildlife viewing, though the wet season floods expand the lagoons and attract more migratory birds.

Local food: Try freshwater fish dishes such as fried mojarra or guapote served with rice, beans, and fried plantains at simple local sodas along the riverfront.
