Los Chiles was originally settled by fishermen and others who worked on the nearby Río San Juan in Nicaragua. It was granted the title of "ciudad" (city) by a law of May 4, 1970. During the 1980s, it was a strategic location on an important supply route for the Contras fighting to overthrow the Sandinista government in Nicaragua, and during that time military men from the United States were a common (albeit illegal) sight on the streets on the town.

Los Chiles is a "border town," only four kilometers from Nicaragua. The vast majority of the population of the city was born in Nicaragua. The Río Frío, on the western edge of town, is a major thoroughfare used to access small villages and farms in the surrounding area. The town is also an agriculture and sportfishing center. A gas station is located here, the only one for 20 kilometers in any direction, and a civil guard checkpoint is on Highway 35 south of town. There is a bank and a few basic restaurants and cabinas for lodging.

• Caño Negro Wildlife Refuge: a watery lowland of lush sloughs and marshes, a seasonal lake, and abundant wildlife. Boats can be hired at Los Chiles for traveling the 23 kilometers down the Río Frío to Lake Caño Negro inside the reserve. The area is a birdwatcher's paradise. Tours to Caño Negro from La Fortuna and the Arenal Volcano area come by bus to Los Chiles, where visitors then board canopied boats for the trip down the Río Frío to the reserve. (29 kilometers southwest of Los Chiles via Highway 4 to El Parque, then west to San Emilio, and southwest on Highway 138 to Caño Negro) • Solentiname Islands: an archipelago in Lake Nicaragua. These islands are home to fishermen, farmers, and many painters and crafters. They are reached from Los Chiles by traveling up the Río Frío to the city of San Carlos in Nicaragua, from where boats journey into the lake to the islands.
