Yallahs is a coastal town in Saint Thomas, Jamaica, situated at 17.87°N latitude and 76.57°W longitude. It lies at sea level and had a population of approximately 7,653 residents as of 2010. The town’s name is believed to have originated from either Captain Yallahs, a privateer active around 1671, or the Spanish word “yalos,” meaning frost, inspired by the appearance of the high white cliffs in the area. Yallahs is a vibrant community, bustling with activity during the day and transforming into a lively hub at night, where pan-chicken stalls and small pubs fill the streets with the sounds of reggae music. One of its notable features is the twin salt ponds, which are believed to have formed during the 1692 earthquake when the land beneath them sank, creating pockets of seawater almost entirely enclosed by land. These ponds were once an important source of salt for the region.
The Yallahs River, stretching approximately 36.9 kilometers, plays a crucial role in supplying freshwater to Kingston and St. Andrew through the Yallahs Pipeline. The town is part of Saint Thomas Parish, known for its mountainous terrain, including the Port Royal Mountains and the Blue Mountains to the north. The parish has a population of around 94,410, with 88.2% Black, 7.6% Asian, 3.2% White, and 1% Other. Yallahs falls under the administration of the St. Thomas Parish Council, which is based in Morant Bay, the parish capital. The town is home to various Christian denominations and contributes to the mining industry through gravel extraction along the Yallahs River bank.
