Nicaragua has always attracted an unconventional tourist, starting with the pirates and Californian gold prospectors who came here centuries ago. A new breed of visitor appeared after the Sandinista revolution -- thousands of internacionalistas intent on joining the great leap forward and helping the country's poor and impoverished (the less than committed were wittily referred to as Sandalistas). Those idealists have now morphed into ordinary people doing amazing things, and Nicaragua is now officially a hot spot for volunteering opportunities in Central America. Below is a list of the more established volunteer organizations offered in the country, but just scratch the surface, and you'll find many more. If you are serious about taking up a good cause, you need to commit considerable time (at least a month) and have basic Spanish skills to get the most from your experience.

Granada
