Adventure tourism involves physical activities, cultural exchange, or interaction with nature that provide excitement by pushing participants outside their comfort zone. It may involve some risk or physical/mental effort. Activities range from soft adventures like hiking and cycling to hard adventures like mountaineering and whitewater rafting. Soft adventures have lower physical demands and risks while hard adventures require greater fitness and technical skills. Soft adventures appeal to a wider audience as they can be done by first-timers on shorter tours with lower budgets and risks.
