Zacatillo Island is one of the largest and most scenic islands in the Gulf of Fonseca in eastern El Salvador. Belonging to the La Unión Department, it is of volcanic origin, which is evident in its hilly topography and dark-sand beaches. The island covers an area of approximately 4 square kilometers and is surrounded by calm, crystal-clear waters well-suited for snorkeling and swimming. Historically, the island has been an important base for fishing, and today it increasingly serves as a destination for low-impact tourism. The island's inhabitants traditionally rely on fishing and agriculture, with tourism becoming a growing source of income. The vegetation primarily consists of tropical dry forest and coconut palms lining the coast. From its elevations, Zacatillo provides spectacular views of neighboring islands as well as the coasts of Honduras and Nicaragua, which also border the gulf. The island is only accessible by boat from the city of La Unión, contributing to its quiet and secluded atmosphere.
