Adventure travel is very popular today with people of all ages. In adventure travel, people do outdoor activities in faraway places. There are two types of adventure travel. Soft adventure travel includes mild physical activity, which is fairly safe. Fishing, hiking, bird watching, and trail riding are examples of soft adventure. Hard adventure travel includes more difficult physical activity. It is also more dangerous. You need to prepare and train your body for a hard adventure. Some examples of this kind of adventure travel are white-water rafting and mountain climbing.
    Why are people interested in adventure travel now? One reason is a new interest in nature and outdoors. More people who live in cities now often don’t want to spend their vacations visiting other cities, no matter how famous they are. People can usually visit cities and common tourist sites on their own. Adventure travel offers the opportunity for exciting, new experiences, all with the help of experienced guides.
    Communities all over the world are taking advantage of the new interest in adventure travel. Small towns that had nothing to offer tourists before are now promoting hiking tours, rock climbing, and canoe rides down rivers. There’s adventure waiting for everyone... somewhere.
