Coatzacoalcos, often called **"Coatza"** by locals, is a port city in the state of **Veracruz**, situated along the Gulf of Mexico. It has a strong industrial and commercial identity, primarily due to its role as a major hub for **oil, petrochemicals, and shipping**. The city is closely linked to the **Pemex (Petróleos Mexicanos)** industry, which drives much of its economy.

Historically, Coatzacoalcos is connected to the **Olmec civilization**, one of the earliest Mesoamerican cultures. The name "Coatzacoalcos" comes from **Nahuatl**, meaning *“place where the serpent hides”*, and is associated with the legend of **Quetzalcoatl**, the feathered serpent god who, according to myth, departed from this region.

Despite its industrial focus, Coatzacoalcos has **natural beauty**, including beaches, rivers, and mangroves. The **Malecón (boardwalk)** is a key attraction, offering ocean views and a lively atmosphere. While tourism is not as prominent as in other parts of Veracruz, the city is a gateway to **archaeological sites, ecotourism, and regional gastronomy**.

Spanish is the primary language, and while some people in the business sector may speak English, basic Spanish knowledge is useful for travelers. The city has a warm, **tropical climate**, with hot temperatures and occasional heavy rains, especially during the summer and hurricane season.
