Walking alone at night will probably earn you a couple of catcalls, but women traveling in Panama will not feel overwhelmed by a macho presence. The influx of foreigners in Panama has helped, too.

In Panama City, women dress up in spite of the heat (meaning no flip-flops and shorts), but skimpier wear is accepted in beach areas.
