Though tentative, TingKun speaks directly to me for the first time as he draws a rough map in my notebook so I can piece together where we've been. Borneo Adventure has brought visitors to Nanga Sumpa since 1987. Though I started with the trek to look for orangutans, most people come directly here for the promise of cultural immersion. The community shares the work and its bounty. The Nanga Sumpa families offer boat transportation and porters to assist treks like ours, as well as providing the hospitality, the crafts for sale, and the spices and other food culled from sustenance farm plots. The revenue from the tours and the sale of goods helps communities sustain their traditional culture. Visitors get the rare opportunity to enter that culture, even participate in it, deep in the forest where it evolved. But first they have to get there -- the easy way or the, er, scenic route.
