Before roads and railroads, Lake Izabal was the link between Alta Verapaz and the rest of the world. What is now known as "El Estor" was the landing and trading post for cargo and travelers to frontier towns such as Cobán. Commonly referred to as "the store" in English, the name evolved to its present form due to Spanish-speakers style of pronunciation and spelling.
Recent construction of roads has left El Estor a minor port visited mostly by locals and the adventurous traveler.
The population of El Estor consists largely of Kekchi speaking indigenous people.
