El Yunque
One of the oldest protected areas in the Western Hemisphere, this pristine expanse looks much as it did when Christopher Columbus visited Puerto Rico 500 years ago. Start at the Portal Tropical Forest Center, and then follow a hiking trail to explore the natural splendors of this ecosystem, including an immense array of flora and fauna. If you are lucky, you may get a glimpse of the elusive blue, red and green Puerto Rican Parrot. The new Forest Adventure Tours program offers visitors to El Yunque the opportunity to hike along a trail with a guide.
