International adventure awaits retirees with the time and budget to pursue it, but some cities are better hosts than others, according to a new report by personal finance website InsureMyTrip.

Civil strife, crime, long lines, inaccessible tourist sites, a lack of public transportation, and scarcity of medical facilities staffed with physicians who speak English are just some of the potential pitfalls that can turn the trip of a lifetime into a never-ending nightmare when the unexpected happens, according to the study.

To help seniors find suitable locations, InsureMyTrip, the Warwick, R.I.-based insurance platform, ranked 50 cities worldwide across the four categories of tourism, well-being, mobility, and demographics using eight metrics: quality of things to do; selection of senior tours; available of healthcare; peacefulness, which includes safety, crime, security, and conflict; ease of walking; public transportation; average population age; and population density.
