When it comes to shore excursions, travelers are often steered toward tourist-friendly entertainment rather than the reality that lies beyond souvenir shops. But this year, Crystal Cruises offers one volunteer excursion per cruise, providing a chance for travelers to give time to causes that benefit destinations on their itineraries.

Among the activities available for volunteers: assisting at a burn rehabilitation center in Lima, Peru; working on an urban farm in Cartagena, Colombia; building a park in Puerto Vallarta, Mexico; working with orphans in Rio de Janeiro; painting a school or community center in St. Martin; weeding out invasive species in Honolulu; or restoring the grounds at Fort Stevens State Park in Oregon. Crew members accompany travelers on the excursions, which are free and include transportation to and from the volunteer sites. Crystal runs cruises of seven days or longer, meaning that volunteers still have several ports in which to play rather than work.
