One of the fun historic towns in Puerto Rico is San German. Narrow brick roads give way to a setting filled with old-world Spanish-style homes. This little town is home to one of the oldest churches ever built in the Western Hemisphere. This sense of history is accommodated by the scenic landscape of San German, where inland mountain ranges give way to palm trees and turquoise-colored water at the beaches.
The Puerto Rican Island of Vieques is truly magical. Visitors can ferry over from the main island and swim in its famous bioluminescent bay (Mosquito Bay), where anything coming into contact with the water leaves behind a glowing tail. Mosquito Bay was certified by the "Guinness Book of World Records 2008" as the brightest bioluminescent bay in the world. The Island of Vieques also offers its visitors some of the best fishing spots in the Caribbean. Overcrowding is not a problem is this serene location and amateur fishers are urged to enjoy the surrounding "SEAclusion." Seven miles of beaches and reefs make for a wonderful backdrop.
Horseback-riding tours are a popular activity for couples in Puerto Rico. These tours usually begin at secluded beaches and follow the coast. This is an excellent way to spend time with a loved one and take in the natural beauty of the island. Scuba diving is also a popular activity for the adventurous. The coral reefs of Puerto Rico are home to many different species of crustaceans, puffer fish, and barracuda.
