"It's the sport preferred by lonely psychopaths and aspiring sexual offenders. Hiking has a lot to offer. Spend days in the woods only speaking to random creatures. Go mad with your own thoughts repeating over and over inside your mind. Get mauled by a wild animal. Sit in darkness wondering what lurks in the distance ready to kill you. Fantasize about women. Hiking is a healthy sport for all to enjoy."
―GTA V website.
Hiking is a feature first introduced in Grand Theft Auto V. Many Pedestrians can be found hiking up some mountains, however, the player cannot go hiking like they can.
