It's the adventure-travel industry's worst-kept secret: most big outfitters hire local tour operators and simply modify those companies' itineraries. They send an American lead guide along as a liaison, tack on a few days at a swanky lodge—and then mark the trip up a few thousand dollars. But if you can do without the upgrades, Detour Destinations, a four-year-old company run by former Mountain Travel Sobek guide Greg Findley, can save you cash. It vets reputable foreign outfitters—mostly in Central and South America—and then sells their trips to U.S. customers with only a slight markup. Detourdestinations.com.
