In the lower part of the park we find savannah snakes. Twelve of the country's most important rivers flow through Armando Bermudez and Jos del Carmen Ram rez National Parks. If you enjoy hiking, then you should consider climbing up Pico Duarte. Guides and mules can be hired at the village of La Ci naga, just outside the park's entrance. It is recommended that you go with a guide even though the track is fairly well marked.
Hikers usually hire a guide and a mule or two to carry their packs.
Although many have done it in less time, the walk to the top of the mountain and back usually takes three days from La Ci nega. Low temperatures prevail in this park, ranging between 12 C and 18 C. Freezes and frosts occur in areas like Valle del Tetero, with temperatures of 4 C and 5 C below zero. Just like the Armando Bermudez National Park, this national park has the largest number of water resources. The Yaque del Sur, San Juan and Mijo Rivers flow through the subtropical humid mountain forest in the southern Cordillera. This is the source of the principal rivers, which irrigate the San Juan Valley and provide the neighbouring communities with electric power.
