Northern Thailand is known for its mountainous wilderness and unbeatable scenery. Here you can find Elephant Nature Park, a place where some of the few Asian elephants that are left roam free after years of hard labour in cities or forests. In the park the elephants have found a new life. In 'Return to the Wild' we will have a close look at the park, founded by Lek, Times Hero of Asia 2005. She and her staff of mahouts and volunteers tend to elephants that have suffered wounds or abuse by their owners.
