El Yunque National ForestIm sorry for the loud mouthed kids someone had there in the background!! El Yunque National Forest, formerly known as the Luquillo National Forest, and the Caribbean National Forest, is a forest located in northeastern Puerto Rico. It is the only tropical rain forest in the United States National Forest System inventory. The forest is commonly known as El Yunque, which may be attributed to either a Spanish approximation of the aboriginal Taino word yu-ke which means "white lands", or the word anvil, which means yunque in Spanish. The second-tallest mountain within El Yunque is also named El Yunque. El Yunque National Rainforest is located on the slopes of the Sierra de Luquillo Mountains and it encompasses 28000 acres (43.753 mi² or 113.32 km²) of land, making it the largest block of public land in Puerto Rico. El Toro, the highest mountain peak in the forest rises 1065 meters (3537 ft) above sea level. Ample rainfall (over 200 inches a year in some areas) creates a jungle-like setting - lush foliage, crags, waterfalls and rivers are a prevalent scene. The forest has a number of trails from where the jungle-like territory's flora and fauna can be appreciated.
