We went by taxi to the Punta Calebra Nature Center associated with the Smithsonian. It is located at the entrance to the Panama Canal. For many years, it was in military use and had not been developed; it is now a refuge for marine life and dry forest. We saw large iguanas, osprey and frigates. We visited the aquarium. From the point, we could see ships waiting for their turn to enter the canal.
Nearby, we saw a panoramic view of the Panama City skyline and large yachts in the harbor.
