The Guajataca Forest is located in the northwestern region of the island near Arecibo, one of several national forests in the “karst” country. A hike along its 25 miles of trails is a memorable lesson in the flora and fauna of a humid subtropical ecosystem. Karsts are formed by the dissolving action of water on limestone and similar minerals. The process, occurring over many thousands of years, results in areas distinguished by sinkholes, vertical shafts, and disappearing streams. It is an uncommon phenomenon; among the most notable are those in Puerto Rico, the Dominican Republic and Slovenia. Hiking in Guajataca combines the joy of solitude (in contrast with El Yunque and other natural sites on the island, this forest has few visitors), with the excitement of seeing very unusual topography. Among the places to visit in the forest is Wind Cave, a fine example of how the dissolved limestone forms deposits in dramatic stalactites and stalagmites, columns and other formations, including some that look like needles and flowers. Be sure to hike to the observation tower where you can view the entire expanse of the forest, Guajataca Lake, and the karst countryside.
