While the effects of the current global crisis on Panama's will eventually be felt, for now construction is everywhere.
The city is clean for Central American standards and, depending on the hour of day, relatively easy to traverse. The highlights to visit are of course the Panama Canal (Miraflores) but there is a lot more like Casco Antiguo, Amador (excellent outdoor dining) and Panama La Vieja, the first European settlement on the Pacific.
Did you know Scotland had a settlement in Panama? Didn't end very well though :-).
Fascinating place with fascinating history. Make sure you spend a few days in Panama City when you visit this beautiful country.
