Los Chiles Airport — Los Chiles, Costa Rica

LSL is Los Chiles Airport, a small airstrip serving the town of Los Chiles in northern Costa Rica near the border with Nicaragua. The airport supports limited domestic and charter flights, largely tied to the region's agriculture and to travelers heading toward the Caño Negro Wildlife Refuge, a wetland area popular for birdwatching and eco-tourism. Los Chiles itself is a low-key border town, and LSL functions more as a rural access point than a scheduled commercial hub, with infrastructure reflecting its small population and remote setting along the San Juan River. Most travelers to this part of Costa Rica arrive by road, with LSL serving occasional charter or small-aircraft traffic instead of regular airline service.
