Physical requirements of a tour guide vary depending on the type of tour and destination, but generally speaking, tour guides must have a good level of physical fitness and stamina. This is because they may need to walk for extended periods of time, carry heavy luggage, and remain on their feet for long hours. Additionally, tour guides must have the ability to move quickly and efficiently in a variety of environments. They must also be able to lift and carry luggage and equipment, and be able to respond quickly and appropriately to emergency situations.
