Retalhuleu, city, southwestern Guatemala. It is situated on the Pacific piedmont at an elevation of 784 feet (239 metres) above sea level. Retalhuleu is a commercial and manufacturing centre for a fertile agricultural hinterland. Coffee and sugarcane plantations are most prominent in the locality, but grains also are cultivated, and livestock and bees are raised. There is also lumbering and liquor distilling in the vicinity. The city’s customshouse serves its port, Champerico, 23 miles (37 km) to the southwest, which handles exports of coffee, timber, and sugar as well as serving as the base of Guatemala’s shrimp fleet. Retalhuleu is on the Pacific Coast Highway and is linked by highway to Quetzaltenango; the city is also accessible by air. About 9 miles (15 km) east of Retalhuleu is one of the oldest archaeological sites in Guatemala—Abaj Takalik—where excavations have uncovered temples, ceremonial platforms, and ceramics of the Olmec civilization.
