Mexico

In Mexico, Grylls must find his way out of Copper Canyon, and his only supplies are a water bottle, a flint and a knife. He demonstrates how to build a simple compass and climb sheer cliffs safely. For shelter, he uses ancient caves and makes fire with a traditional "fire saw." Grylls also demonstrates techniques for finding scorpions or grubs and fishing without a rod or line.
