Travelers to Peru can either help or hurt the country’s long-term survival depending on how they plan their trip and how they behave. A good ecotourism reference in the United States is The International Ecotourism Society or TIES (tel. 202/347-9203, www.ecotourism.org ), which defines ecotourism as “responsible travel to natural areas that conserves the environment and improves the well-being of local people.” A handful of Peru’s jungle operators belong to this association. Find out whether your the lodge or agency you have chosen lives up to these basic principles set forth by TIES:
A huge concern in Peru’s main trekking areas, such as the Inca Trail  and the Cordillera Blanca , is environmental degradation as a result of sloppy camping. A wonderful resource for traveling lightly through wilderness is Leave No Trace (www.lnt.org ), which has pioneered a set of principles that are slowly being adopted by protected areas around the world. More information on these principles can be found on the LNT web page:
Great pains have been made throughout this travel guide to recommend only agencies and lodges that have a solid ethic of ecotourism. But the only way to truly evaluate a company’s environmental and cultural practices is by experiencing them firsthand. Your feedback is tremendously valuable to us as we consider which businesses to recommend in the future.
