Hiking is a leisure activity or outdoor recreational activity that involves walking or trekking on trails or paths in natural environments, typically in mountains, forests, or countryside areas. It is a form of physical exercise that promotes cardiovascular health and well-being, and can also provide opportunities for mental relaxation and stress reduction. Hiking can range from short, easy walks on flat terrain to long, strenuous treks over steep, rocky terrain. It can be done solo, with a partner, or in groups, and can include activities such as camping, backpacking, and nature observation. Hiking also provides opportunities for individuals to connect with nature and appreciate the natural beauty of the environment.
