Marcel likes to highlight companies doing a superlative job in Latin America for upscale travelers. Sometimes you may not have heard of these companies because they’re “inbound” tour companies. You contact someone to book a Galapagos tour, for instance, and a company like Latin Trails is the one actually taking care of you on the ground the whole time. We hit up experienced tour planner Marcel Perkins, who is general manager of that company, for advice on traveling in South America.
