My wife and I recently took the El Yunque half-day trip. Tony was our guide. On the way to El Yunque, he gave us a history of the rainforest as well as a history of Puerto Rico. Tony made the trip interesting. He was very knowledgeable about the rainforest and willing to answer any questions that our group had. We actually got caught in the rain while hiking through the trail. While we waited for the rain to end, Tony took the time to give even more history of El Yunque. We continued the tour, all the while, Tony had a great sense of humor. He even knew the spot where the coqui frogs live and had an interesting "talk" with one! As the tour came to an end, Tony was going to take us to a great spot to eat but, unfortunately, we didn't have time. We had a wonderful time, the beautiful scenery and the knowledge of our guide made this trip worthwhile.
