Where is El Yunque National Forest located?

El Yunque National Forest is located in Puerto Rico, which is part of the Caribbean. This rainforest is the only tropical rainforest in the National Forest System of the United States and is known for its diverse ecosystems, rich biodiversity, and stunning natural beauty. It presents a unique combination of flora and fauna, including various species of trees, plants, and animals that thrive in its humid environment.

The forest is a popular destination for hiking, bird-watching, and experiencing the distinctive tropical landscape characterized by its lush greenery, waterfalls, and rugged terrain. It is also a crucial area for scientific research and conservation, showcasing the importance of protecting such ecosystems.

In comparison, the other locations listed, such as Cuba, Palm Island, and the Dominican Republic, lack the unique tropical rainforest designation and specific attributes of El Yunque, making Puerto Rico the clear and correct answer.
