Good morning, folks. Welcome to "The Elephant Walk" . Today we’re going to learn and enjoy the riding of an elephant. The first step in riding an elephant, of course, is to climb onto it. There are four ways. The first is the easiest for the passenger and the most uncomfortable for the elephant. With a command of "Baitho!", the elephant kneels. You climb up to the seat by stepping on the top of the front part of either leg, holding on to the ear, and pulling yourself up. The second way is more difficult. Upon the command of "Utha! Utha!", the elephant lifts either of its front legs and, holding onto the ear, you step onto the leg and are raised up as in a lift. The third is over the backside. The elephant lowers one of its back legs and you simply catch hold of the tail. The fourth, the expert’s way, is by the trunk. It looks so elegant and simple. As the trunk is lowered to the ground, you place your foot in the middle and then hold on to both ears. The result is that you are lifted up and over and onto the elephant’s back. Remember each elephant can ride only two passengers and the third one is from our trainers’ team, who will help you climb onto the elephant and through the entire journey to ensure your safety, and your pleasure.
