Make time to experience the flora and fauna of Puerto Rico’s 36 nature reserves and 19 state forests. Leaving the city behind, a trek in the interior jungles brings about a rejuvenating rainforest nature bath you didn’t know you needed. El Yunque National Forest is a rainforest close to San Juan and filled with rare trees and birds, not to mention the freshest air you will ever experience. Toro Negro State Forest is the highest cloud forest, revealing incredible vistas, hiking trails, waterfalls and natural pools.
Along the coasts, Puerto Rico boasts three of the world’s five bioluminescent bays — what are the chances? — which are filled with microscopic glow-in-the-dark algae. They are the stars of the nighttime tours that boat or paddle through them. Head to Mosquito Bay on the island of Vieques, Laguna Grande in Fajardo or La Parguera bio bay in Lajas.
