Balboa is a former US Canal Zone town sitting at the Pacific entrance to the Panama Canal, about 8 kilometres from central Panama City. It was built in the early 20th century to house the American administrators who ran the Canal and retains a distinct character — orderly bungalows, wide boulevards, and a tropical government-town feel quite unlike the rest of Panama. The Canal was handed back to Panama in 1999, and Balboa is now an administrative district.
The main reason to come is to see ships navigate the Miraflores Locks, a short distance away — this is one of the great engineering spectacles anywhere, with massive container ships lifted 16 metres in less than ten minutes. The Miraflores Locks visitor centre has good exhibits on the Canal's history and construction. Balboa itself has the Goethals Monument, a memorial to the American engineer who oversaw Canal construction, and a pleasant waterfront along the Amador Causeway, a former US military breakwater now lined with restaurants and bars. Cerro Ancón above the town is covered in forest and home to sloths and toucans — an unexpected patch of wildlife minutes from the city. For most travellers, Balboa is an easy half-day excursion from Panama City rather than a destination in itself.
