'Human Safaris' May Be Exploiting Isolated Tribes, Advocates Warn

Mashco-Prio Indians on a riverbank
Advocates are alarmed by dozens of encounters reported in recent years between isolated Mashco-Piro Indians and tourists.

Unscrupulous tour operators in the Amazon basin may be leading travelers alarmingly close to the territories of "uncontacted" people, according to tribal rights groups.

Advocates are particularly concerned about a spate of recent encounters with the Mashco-Piro people, a group that lives in voluntary isolation in Peru's densely forested Madre de Dios region, near the border with Brazil.
