Mona Island: The Galápagos of Puerto Rico -- Off Mayagüez, the unique island of Mona teems with giant iguanas, three species of endangered sea turtles, red-footed boobies, and countless other sea birds. It features a tabletop plateau with mangrove forests and cacti, giving way to dramatic 200-foot (60m) high limestone cliffs that rise above the water and encircle much of Mona.
A bean-shaped pristine island with no hotels, Mona is a destination for the hardy pilgrim who seeks the road less traveled. A pup tent, backpack, and hiking boots will do fine if you plan to forego the comforts of civilization and immerse yourself in nature. Snorkelers, spelunkers, biologists, and eco-tourists find much to fascinate them in Mona's wildlife, mangrove forests, coral reefs, and complex honeycomb, which is the largest marine-originated cave in the world. There are also miles of secluded white-sand beaches and palm trees.
Uninhabited today, Mona was for centuries the scene of considerable human activity. The pre-Columbian Taíno Indians were the first to establish themselves here. Later, pirates used it as a base for their raids, followed by guano miners, who removed the rich crop fertilizer from Mona's caves. Columbus landed in Mona during his 1494 voyage, and Ponce de León spent several days here en route to becoming governor of Puerto Rico in 1508. The notorious pirate Captain Kidd used Mona as a temporary hideout.
Mona can be reached by organized tour from Mayagüez. Camping is available at $4 per night. Everything needed, including water, must be brought in, and everything, including garbage, must be taken out. For more information, call the Puerto Rico Department of Natural Resources at tel. 787/721-5495.
