Río Dulce is a prominent river in the Izabal department, connecting Lake Izabal with the Amatique Bay on the Caribbean Sea. Along its 43-kilometer course, it passes through the "El Golfete" ecosystem, a wider section of the river that serves as an important protected area for the endangered Caribbean manatee. The river's most spectacular part is the canyon near its mouth, where limestone walls up to 100 meters high, covered in dense vegetation, line the waterway. Historically, the river was of strategic importance for protection against pirate attacks, which led to the construction of the Castillo de San Felipe de Lara fortress in 1652 at the entrance to Lake Izabal. The region is now a major tourist destination, known for its sailing harbors, thermal springs, and rich birdlife. The convergence of freshwater and saltwater ecosystems creates a unique biological niche that includes both mangroves and tropical moist forests.
