This study investigates how the physical and scenic components of trekking in Vally of Flower National Park are affected by observed variations in rainfall, temperature, and land cover. The impact analysis is structured on a hazard-activity pairs method, which combines factors of environmental change (such as greater temperatures) with tourism activities (like trekking and sightseeing). The findings imply that warmer temperatures and less rain have decreased the chances of landslides, rock falls, and mountain sickness, and also enhanced the physical conditions for trekking. It is now possible to enjoy more flowers and greenery while witnessing fewer animals, waterfalls, and snow due to changes in land cover. In the short term, the melting snow may encourage “last chance tourism,” boosting travel, but over time, the disappearance of the snow and the destruction of the forest will probably lead to a decline in tourism. The research concludes that the most viable strategy for reducing losses is the efficient management of the attractions in the developing heathlands.
