An exhibit about Inka Road or Qhapaq ñan (literally the Royal road) opened in June 2015 at Smithsonian Museum of the American Indian, Washington DC. This exhibit offers a wide breath of cultural knowledge and carefully describes many aspects related to the monumental Inka engineering achievements. Knowledge about the engineering aspects of the Inka road were obtained by reversing engineering segments of the 4,800 km route. Three expeditions into the high cordillera of Perú supported this work. Using satellite equipment research teams successfully broad cast back to the Smithsonian from the cordillera and provide visitors in Washington a live experience of the road’s environment. The program replicated for the viewers an expedition walking the road and provide a deeper insight into many aspects of Inka engineering. This enriched experience provided knowledge for the exhibit and provide the bases for cultural tourism programs in the field. The expeditions were developed in a way that produced in its members and those at the Smithsonian an immersion cultural tourism experience. This paper present the features of a field experience approach for cultural tourism identified through analysis and discussion of these successful excursions and the exhibit in Washington. The approach replicates in some degree the research expedition and can serve as a model for cultural tourism programs of historical heritage infrastructure that are difficult to reach.
