My wife and I visited Puerto Rico in May. We found the most excellent tour guide. His name is Jorge, he does private tours, we met him in Old San Juan. He is very knowledgeable, funny, and very thoughtful...He sold us a tour to the Rainforest and it turned out to be our best day on the island..He gave us his card, and we learned from it that he has a web-site
www.puertorico-tours.com call this guy, you'll be glad you did...
