Panama city limits with the region of jungle cushion that serves to preserve the water reserves of the Canal. At only minutes from the center of the city visitors can find natural parks in which excursions are made in jungle regions so dense that the rays of the sun barely penetrates them. The abundant vegetation and biodiversity of these parks are a delight for those who like to walk jungle trails under the custody of expert guides. The Metropolitan Park, Gamboa, Summit Gardens, the Soberanía Park and the Chagres Park are some of these wonderful natural reserves that enlighten the capital city and maintain its atmosphere cleaner and purer.
