It was not so long ago that these villages, cut off from civilization, never saw any Westerners except for missionaries. Expect an authentic experience at places like Huaorani Ecolodge — the children are adorable and instantly bond with your own kids, putting paint on their faces as a welcome and inviting all to dance in the large meetinghouse. You might also learn to make fire solely from twigs and stone, no matches. Note: You will likely see topless women in these villages, a customary part of their lifestyle. Best for ages 10 to 18.
